    Transforming Research and Education in Australia with pervasive networking

    The deployment of the AARNet 3 backbone and the resultant leaps in capacity and access are transforming the ways in which researchers, educators, administrators and students, discover, inspire, manage and learn.

    The challenges are exciting as we enter a totally new era in communications across national, regional and international boundaries.

    In Australia, AARNet 3 provides a fundamental shift from a “managed service “ environment to a world where operating and developing infrastructure becomes second nature and the challenges of security, quality of service, mobility and authentication are all fundamental to the delivery of high quality real time services.

    The ultimate challenges will be to extend the range of services and applications available to Australian researchers and educators and to broaden the reach of our communities, so as to ensure maximum return on investment to our existing shareholders.


    Dennis Medlow

    Global Product Manager - Command Support Systems, Saab Systems

    Holding tertiary qualifications in Computer Systems and Engineering, Dennis Medlow has been active in the ICT industry for over 22 years - the latter 15 being in Defence related industries. Dennis has experience in a number of roles but specialised in networking and communications early on in his career, developing strategies to introduce one of the first local and wide area networks into Adelaide in 1985.

    Dennis' work over the years has involved introducing common software and networking environments, developing local computer networks, and managing the voice and data network design for the Jindalee Operational Radar network. He moved to Queensland to work with Saab on the original Army digital C2 system which posed a series of engineering challenges regarding how information could be effectively distributed over the battlespace using the somewhat limited radio resources at hand. His team was able to demonstrate the first use of X.400 messaging over a tactical radio network.

    Latterly, Dennis has been working on the successor to that system - the Battlefield Command Support System, and has been the C2 systems manager and later design manager for that project. Last year Dennis was appointed as the Global Product Manager for Command Support systems within the wider Saab organisation.

    Networking challenges in a hostile environment

    Today's military forces are increasingly reliant on the timely gathering and distribution of information across the battlespace. The concept of the 'digitised force' has moved from idea to realisation in a number of countries. Australia has been one of the world leaders in adapting information technology for the warfighter and Saab has been working with the Australian Defence Force for over 10 years in providing this capability.

    This presentation will examine some of the networking challenges for military systems in the hostile environment of the battlefield. This includes areas such as the need for comms in the digitised battlespace, remote and roming access, network identification and forming, challenges of narrowband radio links and use of commercial software in this environment.

    Higher Education National Certificate Authority - Enabling secure interoperation

    Australian Higher Education Institutions, like other research institutions around the world, need to collaborate with each other and with global research partners; however mechanisms for communication between such groups are often insecure. Insecure communication methods are of particular concern for research because of the need to protect intellectual property. Inter-institution identity management and access control to valuable resources such as access grids, computational grids, virtual observatories and digital repositories are also issues which can hinder collaboration.

    A PKI implementation has the advantage of supporting and/or providing the principal elements of secure collaboration, such as identity, authentication, authorisation, data integrity, confidentiality and non-repudiation, whilst both enhancing and operating with existing authentication systems. Through PKI, an institution can issue digital 'certificates' which identify the owner and can be used for access control, encrypting emails or other documents, establishing secure communications and 'digitally signing' documents.

    AusCERT in conjunction with CAUDIT has been working on a Public Key Infrastructure (PKI) Project to establish a National Certificate Authority for Australian and international universities and research groups interoperation. The first phase of this project will include the development of policies and standards and to implement a prototype certificate management system.

    This presentation will look at some vital issues on how to enable secure interoperation amongst the Higher Education sector while drawing on the experience gained when implementing the first phase of this project.

    Building a Video-over-IP Network for the University of Sydney

    For years, video communication was prohibitively expensive not only in the cost of equipment but more importantly in the on-going charges of ISDN telecommunications costs.

    A couple of years ago the University of Sydney embarked on building a video conferencing Network over the existing IP infrastructure. The first location to benefit from this initiative was the remote campus at Orange. A couple more have since benefited from this positive experience. As the demand for Videoconference for education and administration grew the installation of a videoconference Bridge was implemented to enable multi-point conferencing over IP. All this was made affordably possible thanks to a robust IP infrastructure and the foresight of the network designers to predict the use of broadband applications over the Data Networks.

    This session will discuss the lessons learnt in building a Videoconference network over IP while catering for legacy system to serve the user community.

    Understanding Network Awareness: Guarding the Guards

    Today's business and uncertain geopolitical climate mean network security is a top priority for many companies and a simple search on the Internet will yield thousands of solutions that offer exactly that protection. With so many risks and so much at stake, companies large and small are looking for more ways to ensure the security of their networks.

    Business leaders are starting to realize they can't rely on basic security measures if they want to assure compliance with customer privacy and protection regulations such as Sarbanes-Oxley, Basel II and HIPAA. In fact, analysts say it's no longer enough for IT to simply follow centralized policies outlined by ISO 17799, COBIT or COSO.

    The general approach is to take the firewall and position it as a gateway (or in the case of personal security systems gateways) to scrutinize and alert to threats at strategic access points to the network. In general this system works well. However, given the importance of the data to the organisation, is it satisfactory to rely solely on these guards for your protection? What organizations often fail to realize is that they are chasing a ghost: one's virus and IDS definitions can be up-to-date, server and host based firewalls can be properly configured, patches and software versions current, and yet still be vulnerable to unknown viral exposure. The anti-virus is not a solution but a single preventive measure.

    Wouldn't it be appropriate to provide some form of safe guard that would act as a policing system to ensure that any threat that compromises your ring fence is identified and tracked? Wouldn't it be wise to provide a guard for the guards? The most logical and often overlooked solution is network awareness.

    Network awareness can be best described as a visualization of the living network from the user's perspective (i.e. realizing that each component of the network affects every other one). Network awareness should reflect the people, packets, machines, subnets, sessions, transactions, traffic, and any movement on the network on all layers.

    The key to network awareness is information. By arming oneself with all available data, intelligent, well-formed decisions can be made. It is not the technology that will solve the problem; it is a shift in the overall approach to network management.

    Having a clear picture of the network design empowers the administrators to make not only good decisions, and also to react quickly if the network falls under attack. By recognizing the threats, it enables organisations to isolate the problem, saving both time and money.

    This session will discuss the basics of network awareness, its benefits to the network administrator, protection versus monitoring and using network awareness to reduce the impact of a security breech.

    Prior to this he was the Manager of Systems Engineering at Madge Networks Inc. which was the role that brought him from the UK, where he was a software developer working on Token Ring device drivers and protocol stacks, to the USA where his focus switched from engineering to the customer side of the business. Will graduated from Cambridge University in 1987 with a 1st class Masters Degree in Computer Science.

    Interoperating with Video endpoints of Yesterday, Today and Tomorrow

    William MacDonald will discuss how to overcome the challenges of having endpoints from different manufacturers (all supposedly complying with industry standards) talk to each other once they are implemented. The reality is that even though they comply with the required standards they still do not talk to each other. This is a real problem that videoconferencing administrators are finding every day, especially when upgrading to the new and highly desired H.239 standard. It will conclude with a discussion about ways of overcoming this.

    Network infrastructure at Swinburne University

    The presentation will cover an overview of Swinburne University of technology including the number of students, staff, local and overseas campuses. Swinburne is also well regarded as being at the forefront in respect to the use of wireless technology.

    Four years ago Swinburne received a great deal of publicity in going ahead and implementing a $4M 'state of the art' network. We will summarise what that project entailed and why it was critical to our business needs and why it now needs to be replaced.

    Swinburne has just recently had approval by its University Council (April 2005 )to proceed with a significant investment far greater then the last time, as the previous network infrastructure has now been used for the past 4 years and is regarded as nearing obsolescence.

    This presentation will highlight the approval process, including Swinburne's particular business case, the technology we will be implementing (ie., 10/100/1Gb to the desktop, all with inline power, Cisco's Security Agent and another 3000 VOIP handsets). The discussion will then highlight how this new technology from Cisco Systems will be used to enable our organisation to deliver excellence in relation to teaching, learning and research.

    Finally, as part of the business drivers the financing of this project via Cisco Capital will be discussed. This lucrative financing approach will enable the organisation to completely replace the network infrastructure, gain quality of service across its three divisions, five campuses and all 18,000 network ports within five months will then enjoy the benefits of a world class network. This approach will be compared and contrasted with what is still a common approach of replacing 25 to 33 percent of a network annually to then gain complete quality of service in three or four years (in time to then start again).

    How Secure is the Network? Assessing Network Risk using a Formal Methodology

    UTS has been developing and refining its IT security policy and procedures for over five years. These procedures include a formal methodology for assessing the risk of IT systems and resources. This methodology was first employed to perform a high level risk assessment of all major IT systems within the University, and the results of this assessment were used to prioritise systems for a more detailed risk assessment. Following its successful application to detailed risk assessments of a number of major corporate systems, the methodology was used to carry out a risk assessment of the network in 2004.

    This presentation will describe the UTS risk assessment methodology, and how it was applied to the network. It will outline the steps involved - dividing the network into its core components, conducting risk assessment workshops on each, developing risk mitigation strategies, and then preparing a risk management plan. The final stage involves documentation of the whole process in an IT system security plan.

    The presentation will describe UTS experience with performing the network risk assessment, the resources required and their sourcing, and the lessons learnt from the exercise.

    Protecting data recovery resources and business-continuity

    This presentation discusses some of the shortcomings of traditional manual and signature-based methods for data recovery resources, when confronted with mutating or previously unknown threats. Methods and technologies are presented, which can be used to protect business continuity even when attacked by zero-day worm outbreaks. Some case studies will be used.

    The principle of 'network self-vaccination' is explained, a three-step process, which largely utilizes existing network infrastructure, combined with new technologies, to dynamically arm a network against zero-day threats.

    The presentation is aimed at network security as well as operational staff and management. A brief introduction to the various technologies and concept will be given, to make the presentation accessible to a wider audience.

    Researching Malicious Code

    Researching malicious code involves a lot more than a large collection of yesterday's virus samples, spams, scams and phishes. (Of course, a well-organised historical collection is vital if you hope to understand what tomorrow's threats are probably going to look like, but it isn't enough on its own.) Analysing and understanding malware is a little like being a code breaker. Faced with the Enigma machine, the Allied code breakers of the Second World War might easily have given up the task as impossible. They needed not only to understand the device in theory, but also to design and build practical tools for cracking messages every hour of every day. Even more importantly, they had to face enhancements and changes which were deliberately introduced by the enemy to put their research out of date. Similar drive and intelligence is required by malicious code researchers, who need to be able to:

    • Disassemble machine code;
    • Reverse-engineer proprietary file formats;
    • Prepare sacrificial networks which emulate the internet;
    • Remember the details of documented and undocumented OS functions;
    • Recall the makeup of thousands of existing viruses and Trojans;
    • Understand cryptography and compression algorithms;
    • Work under pressure without sacrificing accuracy;
    • Maintain an unrelenting respect for security and safety.

    This talk looks at the history, and the likely future, of malicious code and our defences against it. We need to work ever smarter, as we face an enemy who is increasingly motivated by criminal reward, rather than merely by the 'counterculture one-up-manship' of the past.


    Roy Meuronen

    Network Specialist, Networks & Communications, Division of Information The Australian National University

    Roy Meuronen has worked in a system administration role for over 16 years in the government, private, and more recently, higher education sectors. Initially involved with Unix systems, he has been full-time networking now for over 3 years.

    His current roll as Network Specialist with The Australian National University sees him involved with the day-to-day running of a large, converged campus network, as well as finding ways to implement "cool" stuff such as wireless access and TV reticulation.

    The ANU TV Convergence Project (work in progress).

    ANU Networks and Communications have begun a project to replace existing TV reticulation infrastructure and expand the services beyond the current scope.

    The intention of this presentation is to share our experiences so far in implementing this new technology, updating existing infrastructure to cope, and dealing with the associated vendors and stakeholders. It is a work in progress, so much of the detail will be filled out between now and July. This presentation will not contain any rocket science.

    The university currently runs a television reticulation system that distributes video content from free to air satellite and terrestrial broadcasts to selected locations across campus via an analogue optical fibre network. This infrastructure is running at capacity. Our intent is to replace this ageing technology with a more scaleable and flexible solution.

    A TV over IP solution will replace the existing analogue fibre infrastructure, with multicast digital video streaming and Set Top Boxes (STB) connected to the data network.

    The TV reticulation solution can then be expanded to provide access to TV content at the desktop. The system should maximise the value of existing satellite receiver infrastructure, enable additional content sources, and provide an outlet for local content producers.

    Issues covered will include:

    • Description of network topology
    • Satellite to IP gateways: Hardware, Video streams, Limitations
    • Set top boxes: Hardware, Configuration, Limitations
    • Multicast issues: Addressing, Performance, Scope, Traffic levels, Hardware issues
    • Non-technical issues: Broadcasting Act, What channels to distribute? Who gets access?
    • Other sources of content: Terrestrial digital television, TransACT, Internet multicast, Local content, Peering with neighbouring institutions
    • TV to the desktop: Client software
    • Looking to the future: Recording, Archival, Video on Demand

    Networking Landscape at the University of Melbourne

    2004 has been a year of intense planning in the network arena at the University of Melbourne, more so than a year of network change. During this time the University has developed a high level network strategy that had three main thrusts:

    • Telephony Services - development of an overall telephony and voice services strategy
    • Core Network Renewal - the core network is approaching 5 years of age, and will need to be refreshed. What fundamental changes in capability and performance are needed to support the University through the next five years
    • EndPoint Management - a philosophical change for Melbourne - have the entire network managed by a centralised function. What does this mean at the coal face

    The presentation will discuss why these three are the core thrusts for networking at Melbourne, and what has been achieved in the journey so far, what has been learned and what has yet to be achieved.

    Planning and scoping tends to identify other issues that need to be resolved simultaneously, and the issues that have arisen will also be introduced. These issues are not always technical in nature - in fact, there are many management and legal issues to contend with. What is network's role in these?

    The EndPoint Management thrust is the vehicle to implement a key recommendation from Gartner Group (for the Network team to manage the entire network for the University). This will introduce change to the University that is both welcomed, and resisted - sometimes by the same people. The presentation will discuss the process the University will use to manage this introduction, and define a number of the subject areas that will need to be agreed before a managed network service can be implemented.

    The university has not stood still - in fact a number of significant changes have been successfully implemented, that will form a strong foundation for the work ahead. Improvements such as the 'Rings' project have implemented network conduits around the campus, and have enabled a major upgrade of fibre capacity across the Parkville campus. Significant infrastructure improvements at regional campuses have modernised their network capabilities, allowing newer functionality such as video conferencing and wireless LANs to be introduced at the 11 campuses.

    Finally the plans for the next three years will be outlined to demonstrate how the planning will develop into real deliverables, producing real change and value for the University.

    Virtual Private Networks - More, Much More than IPsec Tunnels

    While in commercial parlance the term 'Virtual Private Network' is generally taken to refer to a construct based on IPSec tunnels, these are merely the tip of a very large iceberg. In fact the Virtual Private Network concept is much more general and powerful. The growing commercial offerings based on the BGP/MPLS VPNs defined in RFC2547 and the further technical development associated with RFC2547bis demonstrate that there is a great deal of interest in further evolution of the concept. Indeed the operation of two IETF Working Groups directly addressing this area, with two RFCs so far indicates that there is much more to come at the standards level.

    Although much is happening at the networking level, we believe that the full power of VPN technology will only be unleashed when virtual networks can be created and operated at the user level. The Web/Grid Services paradigm promises a rich context in which to develop the required functionality and recent work within the Global Grid Forum is exploring this territory. From a networking perspective the control plane appears to be the right environment in which to develop the functionality to link the services paradigm and the VPN components as provided, for example, by RFC 2547. Indeed the emergence of sophisticated control plane functions in optical networks reinforces this view.

    This presentation will provide an overview of these developments from an architectural perspective and discuss their potential application in high speed application areas such as Astronomy. I will then describe the research in this area being conducted within the CSIRO Information and Communications Technology Centre. The ideas will be illustrated by a particular VPN concept developed as part of the CeNTIE project. This was motivated by requirements in the Film and Television Post Production Industry revealed by CeNTIE's Media Focus Group but may well be present in other areas such as Supercomputing.

    Cross-domain dynamic services and SLAs

    It is hard enough to guarantee services within a domain that you control. How do you do bandwidth guarantees, service guarantees, dynamic L2 and L3 VPNs, etc. across multiple administrative domains? This talk talks about how you can do it with today's technology and has a look at how you might do it with future technologies. Very hot topic in Academic backbones today, especially with the advent of hybrid packet/optical networking.

    Networks Team Leader at Charles Sturt University

    Tim Rayner has a BE & BSc from UNSW, and experience in the telecommunications industry - prior to joining Charles Sturt Universities' networking team 12 years ago. During that time ha has overseen the development of CSU's network through a number of generations to the recent roll-out of new gigabit campus networks. He has an ongoing interest in charging for telephone and internet usage, and has designed and developed CSU's communications charge recovery systems over the last 10 years.

    CSU NetReg: The Why and How of registering computers and charging for network access at Charles Sturt University

    CSU has recently implemented a new system for registering computers for access to our network. The system centralises registrations - based upon mac address - across all campuses - including student residences. Registered computers are levied a monthly access charge. Staff members are permitted to ad-hoc register computers for network access. Ad-hoc registrations are levied a daily access charge, but are prevented from communicating with most registered computers to prevent virus propagation.

    The presentation will discuss the techniques used to implement this system and the lessons that we've learned along the way.

    The system also provides an interface for budget managers to review, report on and modify registrations for computers or telephone extensions belonging to their account codes. This interface to the system will be covered briefly.

    The Evolution of Security: Network Intrusion Prevention

    Over the last 10 years, we have seen mainstream adoption of the Internet, opening opportunities for business as well as threats. In the arms race against threats, security products have evolved from traditional firewalls to deep packet inspection firewalls, anti-virus products and detection systems to proactive prevention systems that protect the vulnerability. Although the number of new threats is increasing and the vulnerability to exploit window is shrinking, intrusion prevention systems (IPS) are continually evolving and are constantly updated with the latest protection. We have reached a point of dependence upon our networks, and IPS is the convergence between networking and security.

    Intrusion Prevention Systems have come a long way since they were first introduced by TippingPoint in early 2002. They were developed in response to a need for another layer of internal and external protection. Attacks were becoming more sophisticated, bypassing firewalls and alerting Intrusion Detection Systems. Since detection systems were reactive, prevention systems were designed to examine the packet in its entirety and block emerging attacks.

    Today, Intrusion prevention systems have been successfully deployed in several of the Fortune and Global 1000 companies as well as universities, and are blocking millions of attacks. This session will help explain intrusion prevention systems. Because of their ability to deeply classify traffic, IPS's have evolved to manage traffic, shape bandwidth, and enforce policy. The audience will get to hear about some real world educational customer case studies on saved bandwidth, ROI, and blocked attacks. Future applications of Intrusion Prevention Systems are limitless.

    SIP Enabling Real World Multimedia Collaboration

    With the recent proliferation of affordable IP broadband services the time is right for an increase in real-time multimedia communications, however connectivity is not the only requirement to achieving effective and convenient communication services. Protocols such as Session Initiation Protocol (SIP) and Session Description Protocol (SDP) are key to ensuring the seamless user experience that will lead to general uptake of emerging collaborative applications.

    Understanding both the technologies driving real-time multimedia collaboration and the acceptance and use of these technologies through the experience of our own customers and employees, this presentation will show how these communications can enhance productivity, positively impact the bottom line, and improve the user's quality of life through more flexible work/business/study practices.

    This presentation will discuss some of the key trends and technologies which enable the cost effective deployment of collaborative applications and the real-world benefits your students and academic & administrative staff could realise. Examples of applications and how the product is architected and deployed will be discussed. This will highlight some of the benefits and challenges of a network-centric architecture and point to some areas still requiring innovation. Real user experiences will also be presented to highlight both sides of the multimedia collaboration coin - technology and user experience.

    Achieving high performance file transfers across gigabit networks.

    Most un-tuned TCP/IP implementations cannot use 1Gbps of capacity for long distance file transfers. This presentation examines the common constraints and examines TCP/IP tuning parameters to partially overcome these constraints.

    New transport-layer protocols and algorithms have been developed to overcome TCP/IP's limits on file transfer performance and this presentation looks at two: BIC TCP, which is integrated into Linux 2.6, and FAST TCP, a proposal currently before the IETF.

    Finally, hardware performance issues are examined. A checklist of features is provided for use when acquiring computers for the purpose of long-distance file transfers.

    Yet Another Data Aggregator(YADA), an Oracle-free Oracle

    Networks produce huge amounts of data. Data such syslogs, netflow-records, call-records, packet-traces and debugs can be generated in tens or even hundreds of millions of records per day. Within this data is contained incredibly useful information about the state of your network. The problem is, "How do you get this information out?" Traditional RDBMS are clumsy for the streaming nature of these records. Not only are they slow but they tend to absorb huge amounts of storage. And let's face it, who doesn't see their RDMS as a data prison sometimes.

    YADA, is a set of *nix based tools to store, search, process and present you data while keeping them in the flat-land we know and love. It has familiarity of bash, more flexible than SQL and the speed of C - the "yada --world-peace" invocation is especially useful.

    It has been used to process over half a billion phone records in a short amount of time and produced meaningful results. I will explore the methodology of its development and its application to real world data analysis problems.


    Ruston Hutchens

    Network Engineer, AARNet

    Ruston Hutchens is a Network Engineer, for AARNet and is currently working on SIP voice and video service development, and assisting with the AARNet 3 network roll-out.

    Ruston holds a B. Sc (HONS) from La Trobe University, where he worked for seven years.

    AARNet SIP-H.323 Gateway Project

    Over the past few years we have seen competition for 'market share' between the IETF SIP [RFC: 2543, 3261] and ITU H.323 protocols for call control of voice and video over IP sessions (calls). Until recently the majority of deployment has been of H.323 based equipment. As a result, the interest in voice and video over IP based networks in recent years has resulted in a wide deployment of H.323 equipment. However, fundamental weaknesses in the H.323 protocol, and increasing vendor interest in SIP have resulted in an extraordinary take-up of SIP in the last twelve months.

    AARNet has an H.323 network which connects in excess of 2,600,000 voice calls per year, as well as significant numbers of point-to-point, and point-to-multipoint video calls.

    With the majority of current interest in voice and video over IP being SIP focussed, but with a huge deployment base of H.323 equipment, a way is needed to bridge between these two incompatible protocols.

    This paper briefly outlines the relevant parts of the SIP and H.323 protocols, and how they are used for call control. It then discusses the aims and objectives of the AARNet SIP-H.323 gateway project. Details are given of the implementation methodology, and system configuration. Finally it outlines the performance of the implemented SIP-H.323 gateway, and discusses opportunities for use within the AARNet member community.

    James Argyros

    CSIRO ICT Centre

    James Argyros started his career in Physics, specifically Astrophysics in which he gained a PhD, then migrating into scientific computing, and finally network programming; James has had a continuous involvement with networks and network management since the late 1980s. In this period, his work has ranged from using a dialup service into a mainframe to network programming for the Compact Array of the Australia Telescope, until finally he bought the first router for the CSIRO Marsfield site in 1990 - a Cisco CGS. Since that time, he has managed upgrades to the routers and the bandwidth from that site several times culminating in the MAN: MARSHNet that came on line in 1997. He was one of a team that designed and built MARSHNet using E3 microwave links to provide a high bandwidth ATM network integrating data, video and voice. Most recently, he has been involved in the design, building and operation of the CeNTIE networks

    High bandwidth applications development using the CeNTIE networks

    The Centre for Networking Technologies for the Information Economy (CeNTIE) is a joint initiative between the Department of Communications, Information Technology and the Arts and the CSIRO through its ICT Centre. It demonstrates the value of advanced technology and applications to industry and the research community.

    CeNTIE has developed an advanced network research testbed and a range of technologies and demonstration applications designed as a glimpse into the technologies that will power the future, information-based economy. These applications include the Virtual Tea Room, ViCCU® (Virtual Critical Care Unit), EoD® (Extranet on Demand) and Measuring the Network. Each of these systems has presented unique challenges in both the technical and human factor aspects of advanced networking.

    One of the fundamental aims of CeNTIE's research program is to promote advanced networking technology to enable people to interact naturally with one another when they are physically separated. Conventional videoconferencing provides only a marginal improvement over the telephone. CeNTIE has addressed this need through the development of the Virtual Tea Room, an application that uses DV (digital video) over IP to provide an extensible and flexible telecollaboration environment. This environment exploits the high-bandwidth and multicast capabilities of the CeNTIE network to enable simultaneous multi-site conferencing.

    ViCCU® is a system developed for the e-Health industry. It has built on the technology of the Virtual Tea Room to provide virtual critical care in rural hospitals that do not have specialist medical staff onsite. A pilot system linking The Blue Mountains District Hospital with Nepean Hospital over the CeNTIE network is now in its second year. It is used routinely to treat patients and has yielded some impressive clinical results.

    Sydney has a dynamic media post-production industry. This industry is characterised by small companies simultaneously working collaboratively and competitively on a project-by-project basis in digital media creation. This presents enormous challenges to traditional telecommunications services and has led to the development of the EoD® prototype. Once again, a pilot system is in operation on the CeNTIE network linking several of Australia's leading post production companies.

    Underlying all of these applications is the network infrastructure. Critical parameters of any network are throughput, latency, jitter and data loss. These become especially important in the context of audio and visual data streams. It is well known that it is better to lose a few frames of video rather than a single packet of audio. Before starting on a particular project it is essential to know what the network will support. As part of an ongoing effort to provide answers for new projects, Measuring the Network attempts to quantify these parameters.

    Enabling the Wireless Campus

    Wireless Communications today encompass an increasingly wide cross section of technology, ranging from mobile technology such as EV-DO through to Wireless LAN and WiMax. The application of such technologies enables ubiquitous wireless coverage within and also beyond an educational campus environment. At the same time, the prospect of ubiquitous coverage also opens up new application possibilities such as surveillance, e-learning and peer-to-peer networking. This session considers the attributes of the different wireless technologies and illustrates their real world application with a number of case studies.

    Switching over to IP Telephony

    This session discusses some of the challenges facing organisations switching over to IP Telephony. Over the last three years or so, we have really seen the pace of adoption for IP Telephony (IP Tel) picking up. This is largely due to the acceptance of IP Tel as a feasible technology and its tangible business benefits to the network, combined with 'end of life' approaching for circuit switching PABX systems. There are three key scenarios that organisations are faced with when switching over to IP Tel:

    • Co-habitation of existing PABX and IP Tel
    • Pure IP Tel; and
    • Outsourced IP Tel, either through hosted or managed IP Tel

    This session discusses the common and unique challenges represented in each of these scenarios, based on the objective that the end user's telephony experience should be improved by the move to this new technology.

    User Controlled Services - A Reality with Next Generation Optical Networks

    A new breed of telecoms 'operator' is emerging and with them, a new vision of optical applications is being pioneered. Research and education sector service providers such as CANARIE, SURFNet and AARNet are at the forefront of this paradigm shift and optical infrastructure is the vehicle.

    User-controlled ultra high bandwidth services is the goal and technologies such as Next Generation Modulation (NGM) and Automatically Switch Optical Networking (ASON) are key tools in making this achievable. This presentation will look at these technologies and others that are available now or in the near future that make user controlled optical services a reality.

Steve leads a small team providing an excellent service to the ECU community.

    Integrating voice, video and data networks

    Edith Cowan University commenced the move towards VoIP and IP Telephony in 2003. A trial project was started, but the result concluded that VoIP was a venture that needed to be carefully considered - some products were relatively closed in their approach, and there was a danger of being 'locked-in' to a particular vendor or service.

    After the AARNet SIP workshops in 2004, ECU revisited the VoIP/SIP arena. Careful product selection and a concentration on open and agreed standards resulted in an effectively converged set of IP-based telephony services and an extremely successful pilot programme. ECU has developed a strong platform for future development, with a current capability for providing anywhere, any-client voice/video service.

    The ECU Advantage: Ubiquitous computing enhancing teaching, learning and research

    This presentation will cover the history and development of the Edith Cowan University Advantage program. This is a key strategy for ECU to improve its basic student services in C&IT, enhance online learning and create innovative environments for teaching.

    ECU has a strategy to become a stronger University and enhance teaching through innovative research because of the University's excellence in collaboration and improved practice in the professional field of communications technologies. Pursuing this strategy, ECU signed a 10 year strategic alliance with IBM, and has a strategic alliance with Nortel for the provision of wireless networking technology.

    ECU Advantage was forged out of the alliance with IBM and involved in stage one, the implementation of a pervasive wireless network and provision of over 100 laptops to students.

    The initial aims of the program were as follows:

    • Supporting the use of notebook and wireless connectivity to assist students to achieve successful learning outcomes in an exciting and stimulating fashion
    • Developing students' confidence, knowledge and skills in the selection and application of technology appropriate to their field of scholarship
    • Achieving an institutional advantage over competitors by adding value to the teaching and learning experience
    • Expanding students' use of online resources and information at ECU (i.e. learning management systems, library etc)
    • Enhancing flexible delivery options for staff and students
    • Making better and more efficient use of space
    • Developing new teaching and learning models utilising mobile computing technologies
    • Integrating technology into the university experience for academic staff by providing educational design opportunities, infrastructure and support.

    ECU Advantage was implemented in July 2004 and was externally and independently evaluated by Drs Towers and Hearn from the Faculty of Creative Industries and Applications Centre at Queensland University of Technology. Additionally, the academic staff engaged in the three pilot projects were required to submit research on the use of ubiquitous computing and wireless networks and their impact on learning. These evaluations will be synthesised and the key findings presented.

    The technical preparations for this program have been vast and were based on visits to five international 'laptop' universities in North America and the United Kingdom and two global network vendors Cisco and Nortel. The planning, selection, installation and operation of the wireless network, and laptop technology has been thorough and case material will be presented on this process. ECU received world-wide publicity as it launched one of the first wireless mesh networks in the world. This unique technology has provided ECU with an expansive wireless network leading to further interesting developments.

    Overall, this paper will have implications for the way courses are planned and delivered using mobile devices. The presentation will also take a technologist's view of the steps needed to configure the University network to handle the additional services and load. Behind the scenes work on testing, preparing and delivering robust laptop technology will also be covered, along with insights into how to build and sustain strategic partnerships with key suppliers when devising innovative teaching and learning strategies.


    Pascal Fanton

    APAC Sales Director, Crannog Software

    Pascal Fanton has 13 years of experience building & leading sales, marketing and operations for both start-up and established high-tech companies across EMEA and APAC regions. This includes companies such as Philips Communications, Quallaby, Ganymede, NetIQ and Crannog Software. He graduated with a master in Telecommunications and Networking, and has focused his past 8 years building business for Network and Application Management companies, analyzing market trends, evolutions of customer needs and studying the impact of new technologies.

    'Think outside the Box' - Network Management, capacity planning

    The first part of the presentation explains the different markets of Network Management. It will include a discussion on:

    • The market trends, including an analysis of market studies such as by the Gartner Group
    • The factors driving management from 'Nice to have' to 'Must have' and analysis of various factors such as technology, security, business reliability, end user productivity
    • The key drivers for each market segment including SME, Enterprise, Managed Service Provider, Telco

    The second part gives a brief overview of the negative side of network management and why many management tools end up as 'shelfware' ie. they sit on a shelf and never get used. Some Enterprise NMS systems cost the same or more than the network they were managing. Usually they present technical information geared to technical people with limited use for general network users, line managers and senior business managers. This usually requires several applications by different vendors to provide full functionality which means more training, more administration, and more headaches. This is usually difficult to set up and administer - which adds, moves and changes headaches.

    The next part discusses what you need to know. It describes key information you must obtain to manage your network and prevent problems. With the convergence of security/application/network problems, we can see the emergence of a new standard Netflow/IPFIX. Such a cost-effective technology helps to get the complete understanding of what happens in your network infrastructure. But all information needs to be easy-to-access, easy-to-use and easy-to-read.

    Finally the question is asked, who needs to know? Organisations only have networks because there is a business requirement. As technology progresses and makes everyone else's job easier its' complexities make the IT departments jobs considerably more difficult. From a business perspective, things like internal billing have become increasingly more important.

    For the IT team to become a profit centre they have to be able to properly charge for their services. It's easy to allocate a cost to the PC's, servers, software and infrastructure used by a specific department but without the relevant information how do you charge them for network usage or service time.

    Securing Enterprise IP Telephony

    IP Telephony has not suddenly given rise to a new breed of security threat to voice communications - PABX hacking has been prevalent for decades. However, when you migrate a voice network to IP, a whole new set of vulnerabilities does arise. Each IP device becomes a potential target for hackers, and voice communications are prone to denial-of-service attacks and viruses. To address the specific threats to IP Telephony, organisations need to consider the overall security infrastructure, including processes for patch management, anti-virus protection, backup and data recovery, and operating system upgrades. This session outlines the major threats to converged IP networks and IP Telephony, the establishment and maintenance of a secure, converged infrastructure, and next generation security tools currently emerging.

    'Eggs in the Basket' - how convergence changes the security landscape

    Convergence provides increased functionality and reduced support costs. It also changes the nature of threats and risks, increasing the need for real-time protection, detection and response. The proposed presentation discusses the changing nature of threats and risks and looks at how to mitigate these from a combined response. For example, the annual 2004 CSI/FBI Computer Crime and Security Survey identified Viruses ($55M), followed by Denial of Service attacks ($26M) as causing the greatest losses amongst the 300-odd respondents, well in front of Telco Fraud and Abuse of Wireless Networks. This has significant repercussions on IT managers who are considering moving to IP Telephony on the campus and don't have a 'bullet proof' network.

    The presentation takes a high-level (rather than technical) view of the current market and drivers for IP Telephony, and analyses the security threats in both a traditional (TDM) and converged (IP Telephony) environment. Using the Confidentiality/Integrity /Availability framework, the presentation identifies the areas of greatest risk, and therefore where increased protection is required. It takes into account new technologies, such as Cisco's 'Self Defending Network' and the role this plays in securing against threats to IP Telephony. The need for 24x7 vigilance is also discussed.

    Peer-to-Peer Phenomenon - How to be combat it now and in the Future.

    P2P: it's amazing how one term can elicit such extreme reactions, depending on whom you're speaking to. There is the public denouncement of the billions of music and movie downloads as outright intellectual property 'theft,' impinging on every person's right to make a living in a capitalistic society; juxtaposed against an equally public outcry of 'freedom of speech.' For individuals, it's opened up a whole new world of communal file sharing, from music to videos to computer programs - all free and all accessible through hundreds of P2P applications, available to anyone with a computer and Internet access. For music industry moguls, it's the enemy, with declarations of illegality and pending lawsuits against 'offenders.'

    For enterprises - especially in the University space, it can be a nightmare, as more and more students (and staff) snatch a significant amount of bandwidth for recreational P2P use - at the expense of academic-related applications. Even when Universities ban P2P use altogether on their networks, employees can circumvent the restrictions by using the illegal and security risky SoftEther-type tunneling applications, which enables users to bypass the corporate network security suite and allows unrestricted entry for potentially harmful content. Universities in Australia have long held to the myth of 'if we don't know what's happening then we shouldn't be held responsible.' It is not by accident that Australian Universities along with ISPs have been the target of Raids by Anti-Piracy groups.

    Higher Educational Institutions and larger organisations, plagued by the same inability to discern P2P, watch as illegal files (including those with sexual or paedophilic content) are shared in the same manner as academic files being used in this intelligent distribution network. For service providers (ISPs), it is an epidemic, snatching 60% - 80% of their traffic day and night, because their network monitoring devices cannot identify P2P.

    The presentation will go on to identify the size and future directions of P2P usage and effective ways of how to monitor and control/eliminate the P2P threat.

    Understanding and Applying the Five Ps of Security Patch & Vulnerability Management

    Is there a simple way for businesses to develop and deploy an advanced security patch and vulnerability management strategy? This presentation will share with attendees how security and vulnerability patching has become one of the top concerns for IT managers worldwide, but has also left many IT teams fighting a losing battle as the job of patching competes with day-to-day system maintenance and security tasks.

    The patching issue became a more prominent problem for businesses worldwide in 2003 when the Slammer worm was unleashed on the Internet. In the first minute after it started spreading, Slammer doubled the number of web servers it infected every eight seconds. Within 10 minutes, 90 percent of all vulnerable machines had been infected - leaving businesses with $1 billion bill to fix the havoc Slammer created. Yet the patch to fix the vulnerability that Slammer exploited had been available for six months. If the majority of those infected had patched their systems, Slammer would have been a minor blip.

    So why aren't businesses catching on to patching? This presentation shares insights on how the bottom line resource and time problem. Just researching the 4,000+ vulnerabilities published by security monitoring body CERT in the last year would demand hundreds of man-hours. And although an IT staff may be online regularly to see what patches are released, they cannot be 100 percent sure that all systems are properly patched.

    This presentation will also discuss the cost issue. Recent research from analysts at The Yankee Group found that it can cost as much as $1 million to manually deploy a single patch in a 1,000-node network environment. The costs include the manual labour involved in fixing problems and system downtime while patches are being applied.

    Additionally, it will discuss how the interval between a vulnerability being discovered and exploited has shortened and why implementing a security patch management program is now a necessity for organizations of all sizes. The 2004 Blaster worm was released just 18 days after the vulnerability it exploited was discovered, and the pace is stepping up. So how should businesses respond effectively to this challenge? Gemassmer answers this question and more.

    Through a detailed explanation of the Five Ps of Security Patch & Vulnerability Management - proper planning prevents poor performance - support IT security success, the presentation will provide attendees with not only an important business maxim, but also a strategic approach that supports improved network security.

    AARNet - Network Engineer

    Stephen Kingham is presently employed by AARNet to Manage the VoIP and VIDEO Services. Prior to that he has spent considerable time with CSIRO and OTC(A), as well as shorter times with DFAT, AQIS and Centrelink (roll out of the 2,000 end distributed call centres and 30,000 telephones.

    Stephen is extremely active within Australia as well as Internationally. Some of his key projects today are:

    • introducing SIP based technology into VoIP and Video and Collaboration.
    • ENUM in Australia
    • Designing new SIP based Services for AARNet Members

    He is the drive, design, and support behind AARNet's VoIP Toll Bypass Service and VIDEO Service provided to AARNet Members. A particularly innovative approach invented by Stephen has been a "QoS Admission" control that ensures VoIP calls are connected if QoS is in fact functioning which has a good chance of wider deployment. AARNet's IPTEL and very successful VIDEO Working Groups are a result of Stephen's initiative and he is a major contributor to these groups. He is a member of the steering committees for both.

    Stephen Kingham represents AARNet in several international forums, some as a senior position:

    • Chair of the sip-h323 Working Group in APAN (
    • Invited member of the auspicious (closed) Internet 2 Real Time Communications Advisory Group.
    • Founding and active member of the Internet2 VoIP Working Group.
    • Active member of the PIC and Working groups.
    • NASM Member - Stephen runs one of the three International Root H.323 gatekeepers that link the worlds advanced Video Networks together using the GDS (Global Dialing Scheme) and is one of the key drivers behind doing the same for SIP based communications.

    Stephen has 20+ years experience in Voice, Data, and half that as SysAdmin. He is equally comfortable operating Voice networks as well as data networks and writing applications to make them work. He has several tertiary qualifications; BSc in Electronics/Physics; Masters in IT; (half completed) Masters in Computing; and Electronics and Communications Certificate.

    Future developments of the telephone service!

    With the coming of age of IP Telephony spawned by the new technology of SIP there is a growing market for third party Telephone Carriers who provide their service using the Internet. Academics, students, staff and the general public are starting to use these services in preference to the telephone provided by the University. This trend will undoubtedly continue.

    This talk reviews the trends occurring overseas, how the services work and why they are successful and what will the telephone service look like in the medium-term and what can Universities do to keep their clients.

    The eResearch Program - Making Networks Work for Researchers

    The rapid evolution of digital, information and communications technologies has created an environment in which the paradigms of research have changed. Over the past few years a number of initiatives in Australia and overseas have been taken to ensure that these opportunities can be effectively exploited, including establishment of the Australian research and education network.

    At the same time the evolution of the capability and sophistication of scientific instruments and facilities has seen an explosion in the quantum of data produced by experimentation, and the complexity of analyses conducted using this data.

    Science, particularly that based on large instruments, increasingly involves distributed, global collaborations enabled by networks and using very large scale data collections, high performance computing resources, tele-science (remote access and control of instrumentation) and collaborative visualisation. Collectively this is referred to as e-Research.

    e-Research involves an evolving new capacity for large-scale, distributed, global collaboration in research, providing a new level of scope, scale and detail. It entails harnessing the capacity of ICT systems, particularly the power of high-capacity distributed computing, and the vast distributed storage capacity fuelled by the constant dropping cost of memory, to study complex systems across the research landscape. It has a number of components:

    • Access to very large data collections,
    • Complex simulations,
    • High performance visualisation , and
    • Virtual research organisations involving researchers distributed geographically.

    These current Australian investments in e-Infrastructure: AREN, APAC, AARNET, GrangeNet, the ARIIC initiatives and investment in major physical infrastructure through the MNRF program and other funding programs, have placed Australia in a position to support e-Research activities that are comparable, and in certain aspects in advance, of that existing in the UK and USA. In addition, the collaboration frameworks established for Australian research provide a much stronger base for e-Research than existed in the UK at the time of initiation of the e-Science programme.

    To ensure that its researchers remain globally relevant and competitive, and to ensure Australia maximises its return on investment from the new global research paradigms, the Australian Government has initiated a coordinated activity in e-Research, to build on and take advantage of recent investments in broadband networks, high performance computing, instrumentation, large experimental facilities, and information infrastructure. This initiative has a clear focus on strengthening multidisciplinary teams working in national priority areas by providing incentives, guided by policies, and participating in international research programs.

    Best Practices in Email Security: How to Handle the Rising Threat

    Jeff's presentation will be titled 'Best Practices in Email Security: How to Handle the Rising Threat' and will focus on the challenges customers face from the ever-evolving security threat landscape. Whether it's protecting against viruses, spam, hacker attacks, phishing scams or future risks related to inappropriate content, policy controls or information leakage, customers have their hands full understanding the risks and finding ways to get effective, yet durable protection over their critical communications. Did you know?

    • 80% of viruses enter customers' networks via email; a typical infection costs up to $500,000-Gartner
    • About 450 viruses are discovered each month-IDC
    • In 2004, more than 8.8 billion spam messages were sent every day-IDC
    • Spam will cost companies $198 billion by 2007-Radicati Group
    • The Nigerian 'prisoner' scam extracts $200M from its victims a year-FBI
    • 51% of users have received pornographic spam messages-Queens University
    • Phishing accounted for $2.4 billion in fraud, or an average of $1,200 per victim, during 2004-Gartner

    Especially when it comes to online communication tools like email and messaging in higher education, security threats jeopardize critical interactions between students, alumni, faculty and staff that can directly impact online learning. Looking ahead, as the message network takes on an increasingly important role with the convergence of telephony and wireless applications, the security risks will compound and organizations unprepared will be at risk of productivity losses, financial and potentially legal risk. Jeff's presentation will overview this evolving threat landscape and provide an education on how attacks are being conducted today, how they are evolving, the types of threats customers should prepare for, as well as the solutions either through education or technology, that can best help customers make email good again.

During his time in this role he created a vision that would provide core redundancy and homogeneity of networking to all staff desktops and student laboratories. He has a PhD in Computer Science.

    GrangeNet II

    Due to the successes of the GrangeNet program a funding extension was granted until the end of 2006. As part of the funding extension a component was allocated for maintenance and refresh of the existing GrangeNet backbone equipment. In collaboration with Cisco an innovative network architecture was developed that permits unparalleled connectivity between researchers that have access to the existing GrangeNet POP sites. The new network supports layer 1, layer 2 and layer 3 services to the GrangeNet community.

    Layer 1 services, commonly called Lightpaths, are dedicated connections between two endpoints that bypass all of the GrangeNet layer 3 routing and layer 2 switching infrastructure. Effectively the user will only see their device at both ends.

    The Layer 2 service is a Local Area Network. Between any Grangenet POP site it is possible to configure the same VLAN. This can effectively create a LAN segment that spans between Brisbane and Perth and all GrangeNet POP sites in between.

    The Layer 3 service is the traditional R&E routed traffic that GrangeNet has been carrying since inception.

    This presentation will be used to describe the logical and architectural concepts that underpin the GrangeNet II network; provide a detailed examination of the interior workings of the new equipment; and provide examples on how researchers can best benefit from this new architecture.

    She considers that in the IT world, it is no longer about ICT working as a separate department but rather as a part of the organisation's core activity and that ICT teams must have input into Strategic Planning, Finance and HR and other departments' roles. Her own role incorporates many of these aspects.

    She describes her strength as "Her Hands on management style: Having worked on Contract submissions, negotiation and management, Customer Help Desk Service liaison and IT service outsourcing projects.

    Wireless Security

    This presentation will discuss detection, location and isolation of rogue devices. It will also describe the first wireless firewall.

    As the need to access information everywhere dominates discussion, so to does the need for all users internal and external to know that the information is secure.

    When wireless was released to the world it became one of the fastest growing areas of all IT equipment. When WEP (wired equivalence protocol) was found to be breakable the corporate market took note and stop buying. However the rest of the market continued to explore and grow their wireless investments as the productivity was improved. Since WEP the wireless manufactures have replaced WEP with WPA (wireless protected access) and WPA 2. Although this has fixed the WEP issue there are so many more vulnerabilities to the wireless infrastructure.

    For organizations with wireless LAN networks, as well as those without, Wi-Fi brings a new set of security threats that cannot be protected against by your current firewall and VPN security systems. Placing your wireless LAN network outside of the corporate firewall doesn't help either.

    Simple to install and low cost, Wi-Fi access points may be brought in and deployed by your own employees, usually with no intention of generating harm. These insecure deployments, called rogue APs, open up your network to unauthorized personnel, making vulnerable your most important asset - confidential information about your business, customers, products and services. Other threats, including denial of service attacks and your own misconfigured APs may lead to additional vulnerabilities.

    This is where AirTight Networks has stepped in to offer the first wireless firewall. SpectraGuard Enterprise solves these problems and many more by providing a complete Wi-Fi firewall, delivering the same comprehensive protection as a wired firewall, but focused on your corporate airwaves.

    Network Management - Effective management of the IT network - and your IT service providers

    Todays' IT networks require a great deal of expertise and specialisation to keep them running - a challenge almost all IT managers face, every day. IT budgets are continually scrutinised and measured, however, the costs of retaining highly skilled staff, in-house, continues to creep upwards.

    IT service providers have been endeavouring to wrestle inhouse IT management functions since the days of mainframe computing with the concept of whole scale IT outsourcing. Despite the many publicised failures of the past decade, there are those organisations that have seen great financial and efficiency benefits from such outsourcing models.

    Conversely, those who have resolutely stood on an in-sourced IT model have managed to shield themselves from the horrific boom/bust times that signified the past 10 years of IT outsourcing. Perhaps they have even used the disastrous IT outsourcing cases to their advantage - as clear examples of what not to do - and they would have been justified in doing so. These organisations, however, have since been forced into outsourcing the areas of their network which are clearly utilitarian, serving little or no strategic value to the organisation (e.g. parts of network security, SPAM, WAN services, etc).

    In fact, most organisations recognise that in today's network there is no single organisation, whether internal or external, that is truly capable of managing all facets of the network.

    Further, with the enormous up-take of a myriad of IP connected mobile devices, the challenges of managing a network successfully are real and require urgent action.

    • How serious are these challenges and what are the solutions?

    The early adopters of whole scale outsourcing and the resolute complete in-sourcing organisations, seem to have reached a comfortable middle-ground. As we move into the next generation of managed network services many organisations, are turning away from both whole scale outsourcing or complete insourcing of their network to a more selective sourcing model to mitigate their risk and work towards their IT service providers strengths.

    • Will the increase in selective sourcing trend of the non-strategic IT network functions continue?
    • What areas should Network Managers be looking towards in their current in-house skill set to manage their entire network?
    • How are organisations around the world managing to working effectively with IT Service providers to provide acceptable level of service and security in so many hetergeneous IT networks?
    • What type of managers are companies looking towards to ensure their IT networks are safe, stable, resiliant, robust and cost effective?
    • Selective sourcing agreements - focusing on a risk/reward partnership, rather than an Service Level battle.
    • How much outsourcing is too much?
