10Gigabit Ethernet (pdf 8.42 MB aprox.)
Since its inception in 1973, Ethernet has undergone massive changes and
visibly re-created itself, all the while managing to look and feel the
same. From the early days of shared 10Mb, through the paradigm shift of
switched Ethernet, to the more recent performance enhancement of Gigabit,
Ethernet has proven itself massively scalable. Now we are weeks away from
the formal ratification of the latest and greatest advance in Ethernet -
10Gigabit Ethernet. This paper traces the history of Ethernet and then
examines in some detail the 10Gig standards road map, the components of the
new standard, the interfaces available, the implications of different types
of fiber on the distance 10Gig can be driven and reflects on likely early
uses for the technology.

Author: John Dunsdon
Job Title: Manager, Network Services Team
Organisation: University of Southern Queensland
Wireless technology has the potential to change the way in which Universities undertake their core business of teaching and the way students learn. Students will have instant access to information and potentially they will have the capability to undertake quizzes online or even undertake course work in venues other than the traditional learning environment.
The University of Southern Queensland has positioned itself as a leader in embracing modern electronic delivery methodologies. This paper provides a case study of a wireless LAN implementation that was initiated to enhance the opportunity for students and staff to access the Internet or e-mail whenever they turned on their notebook, laptop or PC anytime or anywhere on campus.
This session will focus on the drivers for the wireless project initiation and the processes that the University undertook to purchase and implement its wireless LAN. Also discussed will be the issues that the University considered significant in the deployment of its wireless LAN, and the assumptions and constraints that defined the scope of the project.
Presentation Outline:
The presentation will cover the following topics:
Drivers for the USQ wireless LAN
What is a wireless LAN
Tendering process
Scope of the project, assumptions and constraints
Standards, 802.11b or 802.11a or 802.11g

CSIRO Directory Services - Peeling the directory onion without the tears (pdf 3.49 MB aprox.)
The whole research environment has been changing in the last decade and CSIRO, like many other organisations, is reconfiguring itself to meet these challenges. CSIRO is a diverse research organisation with 22 business units operating across 70 sites within Australia. Within CSIRO, an increasing need to collaborate across the organisation is being assisted by projects such as the CSIRO Directory Services Project. This project encompasses a series of changes to the basic Information Technology infrastructure. A major cornerstone is a single authentication domain used to access the business systems used by researchers and support staff on a day-to-day basis. A single authentication domain came as a result of migration of its NT4 master/resource domains to a single Windows 2000 Active Directory domain. CSIRO continues to reap the benefits of this move.
The Directory is becoming a repository for information about people and other objects in its collection, derived from various sources. Business Systems are now able to use it as a source of the information and authentication. The imminent migration
Exchange 2000 will further reinforce the value of the directory.
As with any major infrastructural project, there are the historical contexts, the assumptions and business needs and conditions, as well as the technical and cultural issues that need to be addressed.
CSIRO was an early adopter of this form of technology and the intention is to give some insight into the project's history and the opportunities that it has created and continues to create.

Campus Based Authentication (pdf 1.66 MB aprox.)
This presentation will discuss the various technologies required to build authenticated campus based networks.
Using standards based protocols like EAPOL campus users can be authenticated onto the network and placed into the correct community of interest.
For those users that don't have EAPOL support other options like captive portal implementations are discussed in order to authenticate the user of the network resource.
The presentation then takes this concept to the next level by discussing how the users identity might be tracked using custom built systems and IP Service servers.
Single sign-on is a lofty goal to aim for, however some of the issues are covered in this presentation with a view to inspiring the budding developer into action.

Case Study of Virtual Private Network (VPN) Implementation at Monash University (pdf 0.93 MB aprox.)
The attraction of using the Internet to transmit sensitive data at a fraction of the cost of employing leased lines has driven network providers to come up with innovative solutions for safeguarding the exchange of data over a public infrastructure such as the Internet. The secure overlay that runs over a shared infrastructure to provide such a service is called "Virtual Private Network".
The session will look at how Monash University's expansion globally and nationally, as well as the need for travelling and telecommuting employees to access IT services over the Internet, became the driving forces for implementing an enterprise wide VPN network. Also debated will be the requirement for the University's Wireless LAN users to use the same VPN platform for adequate protection, instead of the less secure wireless WEP protocol.

Computer Network Support for Pervasive Systems (pdf 0.45 MB aprox.)
Recently, we observed increasing user demand for pervasive systems: users often want access to the same computing applications and information on their workstation in the office, on their computing devices at home or on a variety of mobile devices when the users are on the move. The pervasive systems need to be able to deal with mobility of users and their devices and also, in the future, with users who may want to change their computing device while running some computing applications (e.g. change a PDA to a workstation when the user moves to an area where this is possible and still continue the previous computing application).
Pervasive computing infrastructure should allow users to move their computational tasks easily from one computing environment to another and should allow them to take advantage of the capabilities and resources of their current environment.

Firewall Deployment - Bad-Guys Inside!!! (pdf 3.13 MB aprox.)
The need to establish and maintain suitable security policies across an organisation is accepted as a mandatory requirement by every organisation. Yet network and server technology has far outpaced the ability of firewall and other security technologies to meet the exploding bandwidth demands and increasing data complexity within every organisation.
Organisations are no longer restricted to deploying firewall technology on the perimeter of their networks and information resources, based on the belief that the 'bad-guys' are on the outside. As today's networks and business systems become more complex and highly dynamic in nature, it is no longer practical, or possible, to define a clear demarcation between 'inside' and 'outside', or who, and where, security threats originate from. Organisations must now take steps to maximise levels of security to meet their security strategies throughout their organisation, both on the perimeter, and internal to their networks and systems.
This session will look at common firewall deployment models, and emerging opportunities to extend security controls with firewall and associated technologies.

IP Mission Critical Networks (pdf 3.06 MB aprox.)
Today's applications demand network solution's that are highly intelligent and highly reliable, capable of supporting a host of advanced features for high volume traffic handling & processing.
Companies today require specifically designed multilayer switching products developed to meet the most stringent emerging network requirements for IP mission-critical networks.
Today's switch must have a highly intelligent design encompassing advanced distributed switching architecture including state-of-the-art Application Specific Integrated Circuits (ASICs). Modular chassis designs should support high density, high speed, and flexible connectivity of all Ethernet interfaces. Industry standard application-aware networking software supporting feature sets including a full array of reliability, redundancy and resiliency capabilities, wire-speed Layer-2 switching and Layer-3 IP/IPX routing; feature rich robust QoS (L2, L3, and L4), network management & server load balancing.
A highly resilient and continuous switching architecture is key to success in today's networks. Best of breed QoS, and carrier-class resiliency, and robust routing features are typically taken from packet based architecture, while the intelligence, network management and security features should be taken from traditional data architecture.
Availability should encompass device & network reliability, resiliency and redundancy. IP Communications and Convergence, such as voice over IP (VoIP), data, video, etc has created the opportunity for vendors to develop comprehensive product solutions to support network availability to its highest level. In order to be able to provide this convergence, network availability must reach a 99.98% or better up time with 99.999% equalling 5.26 minutes of network down time per year.
Though convergence is a major driver for availability, Network Managers need to be able to keep their user population connected to the resources they need. Today.s campuses are more dependent on their network than ever before. In today.s environment it is crucial that the edge of the campus network is as reliable as the core as this is the source of IP telephony.

IP Paradise 12 months on (pdf 3.22 MB aprox.)
Internet and Ethernet technology and protocols form an irresistible wave, shaping and dominating both present and future media and communication forms.
A network based on IP and Ethernet will be impossible to challenge by any other technology or combination of technologies. High and rising volume under severe competition will guarantee superior price/performance. The network will be able to manage any kind of media, including high-definition video and video-telephony.
Distance will also be eliminated as a problem regarding anything digital. This will greatly improve the relative position of regions that are geographically on the periphery, like Scandinavia and Australia.

Intra-University Authentication and Authorisation (pdf 0.23 MB aprox.)
Most, if not all Australian universities now provide enterprise based usernames and passwords to their staff and students. These usernames and passwords are used for accessing personal or restricted information on the university's web, allowing individually customisable interfaces through portals, access to e-mail, capturing and limiting Internet usage, etc., and in some cases used for all computer based access in a same sign-on or single sign-on scenario. Queensland University of Technology (QUT) has several projects underway that leverages these authentication infrastructures to allow sharing of resources across university boundaries in a secure and controlled fashion.
This paper will provide a case study of two of these projects:
1. Providing access to QUT's Online Teaching System (OLT) to postgraduate students from ATN universities.
2. Providing reciprocal access to lab PCs between QUT and Griffith University (GU).
The Internet community is aware of the problems associated with inter-enterprise authentication and authorisation. This paper will conclude with a brief look at some of the technology offerings available and currently under development, including the Athens project from the UK, the Shibboleth project from Internet2, EZproxy, the Microsoft Passport solution, and PKI.

Netcheck: The Internet Accounting System strikes back! (pdf 0.74 MB aprox.)
Like most Australian Universities, the cost of providing Internet access to the University Community has gone from a small sum in 1995 to being a major drain on precious University funds. The existing Internet Accounting System for staff at Griffith called INAP was only accounting for web traffic through an authenticated proxy service. There was a second system for students called SNAP; which gave student a time-based quota.
In that scenario there was no way of recovering costs for a growing amount of traffic; which led to a heavy reliance on access lists and other measures to try and keep up with the new and creative ways students and staff bypassed the existing systems. An RFO for a new Internet accounting system was put out in the middle of 2000; which eventually ended in the selection of Digiquant (formerly Belle Systems) as the successful vendor and a scoping activity was undertaken in early to mid 2001.
The main project was then commenced and a pilot in the Information Services department began in September 2001 and culminated in a go-live of the "Netcheck" for the staff community in January 2002 and the student community in February 2002.
This paper will cover the implementation of the Netcheck system across the entire University including implementing quota's, new technology (routers, servers, databases, etc), integrating your Internet Management System into ERP systems, project plans, communication issues, pitfalls and the highs and lows of the implementation including current support issues.

Network Longevity and Economic Value of Dark Fiber Options (pdf 0.55 MB aprox.)
Organisations and enterprises alike face numerous challenges when deciding on core network solutions that will deliver long term scalability and value to end users. Decisions employed today can have a significant impact on the networking direction of the organisation in future years. With networks built on open optical metro networks using dark fiber IRUs or leases, operators can be assured that an economical and networking balance is achieved that dramatically lowers operational expenses while matching capital requirements against any form of end user demand.
This paper for both the managerial and technical audience examines the issues surrounding the deployment of metro optical networks, dark fiber procurement issues, and the inherent value of employing optical solutions over other alternatives. In addition, the network dependencies of DWDM and CWDM are presented with a view towards highly available, full wavelength solutions from the core to the computer room door.

Optical Ethernet: combining the power of Optics and the utility of Ethernet - fast, simple and reliable! (pdf 4.09 MB aprox.)
Abstract: Optical Ethernet fundamentally changes the way networks are designed, built, and operated by creating a new networking solution that extends the boundaries of the Enterprise LAN environment to encompass the Carrier MAN & WAN. Optical Ethernet solutions combine the ubiquity, flexibility, and simplicity of Ethernet with the reliability and speed of Optics. This powerful combination creates networks that are fast, simple, reliable -- and eliminates the bandwidth bottleneck between the LAN and the WAN.
Fast: Optical Ethernet provides unprecedented bandwidth ranging from 1 Mbps to 10 Gbps. "Bandwidth by the slice" allows bandwidth to be provisioned in 1 Mbps increments in a fraction of the time previously required: hours as opposed to months.
Simple: Unlike today s networks, Optical Ethernet traffic remains Ethernet end-to-end, thus eliminating protocol conversions between networks and simplifying network topology. Network operations are further simplified by preserving the familiar address management and easy provisioning attributes of the LAN.
Reliable: 90% less latency and 30% less jitter than routed networks translate into superior network performance that is both consistent and predictable. RPR networks can achieve 99.999% availability and restoration times of less than 50ms. Split-Multi Link Trunking (S-MLT) provides industry-leading redundancy and recovery features for mesh networks as compared to spanning tree alternatives.
In this presentation 4 implementation models will be reviewed: Ethernet over RPR, Ethernet over Fibre, Ethernet over WDM, and Hybrid solutions.

Realising the Promise of SIP: Nortel Networks Global IMS Trial Deployment (pdf 5.92 MB aprox.)
SIP (Session Initiation Protocol) is many things: it is new, based on hypertext protocol, a peer to peer protocol, capable of voice, video, and data sessions, part of the 3G protocol portfolio, based on IP, and will be resident on just about everyone's PC in a few years, like it or not.
This paper will ground the 'SIP Hype' with the discussion of Nortel Networks Interactive Multi-Media (IMS) implementation and trial deployment of a 'SIP Switch'. Architectural elements of this solution including the SIP Application Server, Database Server, Management Server, Web Client Manager, SIP Gateways, Real Time Media Portals, Audio Servers, Video MCUs, and Multi-Media Clients will be described, and sample call flows involving the various elements will be diagramed.
Functionality such as integrated video, simultaneous and sequential ringing, dynamic call handling, collaboration, presence, and instant messaging will be described. These are basic building blocks for enriching the communications experience and providing personal control.
Network Security is a top concern today, and especially for any proposed commercial network deployment. The IMS Security Architecture will be presented. Questions such as to deploy multi-media behind firewalls, and how to access a user in a NAT environment will be addressed.
Leveraging off the reach of the Internet, Nortel's IMS implementation was deployed in Texas to server users in North America, Europe, Asia, and Australia. User experiences from each continent along with their network considerations will be shared.
A non-commercial demonstration of capabilities and call flows will conclude presentation.

Trends in Campus Networks (pdf 11.13 MB aprox.)
The architecture of Campus LAN networks continue to evolve to support introduction of new networked applications which themselves have become viable as a result of new technology introduction. The cost of high speed networking technologies continues to decline rapidly to the point where high availability network designs, that were considered prohibitively expensive just a couple of years ago, are now common place. This in turn has enabled the rollout of applications that were previously considered inappropriate for implementation over LAN based networking technologies.
Ethernet and Quality of Service were once mutually exclusive, however today's applications, such as IP telephony, storage networking, and content distribution have driven the evolution of Ethernet to deliver not only QoS in the LAN, but also to address addition requirements of these application such as network security, user authentication, service availability, scalability and so on. The design of core switching elements originally focused on speeds and feeds but today the integration of network services into the switching elements is a key requirement for deploying multiservice applications across Campus networks.
This session examines some of these trends, their drivers and the corresponding implications for the network elements and overall network design.

Victorian Educational and Research Network (VERN) (pdf 0.83 MB aprox.)
A very brief history of the successful Victorian Regional Network (VRN), implemented as the Victorian connection to AARNet2 during 1995, will highlight the outcomes of the VRN's principles of design and management.
The reasons for the need to develop a statewide advanced network including requirements such as improved capacity, flexibility, resilience and to provide access for new resources such as the synchrotron will be explored.
The development of VERN is likely to lead to the collapse of the VRNO state network and sections of existing wide area networks into a single level network. Similarly as AARNet develops, the collapse of national and sections of the state network is possible. VERN business and financial principles will be discussed.
The Hierarchical Interconnected Dual-Anchored Augmented-Rings (HIDAAR) design developed by Neil Clarke will be discussed. The likely technical design and important technical issues will be introduced. The requirements include the provision of independent networks for differing groups and the ability to configure independent connections or networks for specific research projects or testing. The possible implications of fibre properties, the structure of the fibre plant and Coarse and Dense Wave Division Multiplexing will be discussed at a broad level.

We're Not in Kansas Anymore (How the Internet has Changed) (pdf 0.46 MB aprox.)
The Internet was founded by Research and Education institutions working in an open, cooperative environment. The modern Internet is a very different environment in which security, application, technical, growth and legal issues abound. This presentation will look at how the Internet has evolved to address these challenges and what future hurdles remain.

Wireless Networks; Network Security Tools and Utilities (pdf 1.34 MB aprox.)
The University of New South Wales is implementing a 'campus wide' wireless network for staff and students. The initial role out of some 70 base stations will be in launched in August 2002. Standard 802.11b technology will be used, however the option exists to add 802.11a concurrently.
While the basic technology is very simple, from the University's point of view there are two main obstacles to using it: security and cost recovery.
To address the first the University is using authenticated VPN technology to both ensure that users are valid and that traffic is encrypted beyond the (known to be weak) WEP standard. CISCO VPN technology is used.
Secondly, the University charges back Internet traffic on a subnet basis to Schools etc. This is not adequate for a University wide service. The cost recovery mechanism involves real time monitoring of user traffic, charging against a user account and disconnection on exhaustion of funds. Users can pay cash in advance (over the counter or on the web via credit card) or usage can be billed against an internal cost centre. Users can monitor costs via a pop-up web page in real time. The CISCO 'service selection gateway' technology is used for traffic counting/control and imposes no impediment (capacity or delay) to traffic (unlike processor based solutions). The user has volume-charge free access to campus sites, but is challenged to re-authenticate and nominate a cost limit when accessing off campus.
The University also has a 'connection charge' for a network port. We did not want a situation where desktop users were choosing to use the wireless network in preference to the wired network to save the connection charge. The impact of changing to an 11Mbps (at best) shared media from a 100Mbps switched port was felt to the fraught with disadvantages. To avoid this (carefully costed) 'flag fall' charge was introduced for the wireless network, which applies on the first log in per day. This removes the incentive to use the wireless for fixed installations and provides funding to operate the wireless network.
The system is locally developed in final beta test, with an increasing number of base stations and 'tame' users.
The paper will address:
The drivers for the provision of such a system, which include an increasing uptake of laptop computers by students and limits on campus computer labs
The choice of initial locations
Choice of wireless systems and configuration
Support mechanisms for users, including software installation, supplies of cards etc.
The needs for security above that provided by WEP and why we chose not to sue a proprietary WEP extension
The technology used to provide security: the initial closed network and DHCP; the establishment of a VPN tunnel and authentication
The cost recovery environment at UNSW
The cost recovery system for the wireless network for both Internet traffic and operating costs. This will look at both the real-time monitoring and the underlying billing system, which is also used for other purposes (such as dial-up access). Technologies looked at are: interception of Internet traffic, authentication to the 'per-user-billing' system, traffic counting via the SSG, the user pop-up, the electronic invoicing system, the underlying user management and billing system.
Long term plans for the service: additional locations, Faculty involvement in extending the reach of the network, use of the per-user-billing system more generally.
Results so far, including test user experience, costing and problems encountered.
