Background
• AARNet Pty Ltd (APL) is a not for profit company
owned by 37 Australian Universities and CSIRO
• Operates a national network providing commodity
and research Internet access to members (owners)
and other clients (institutions that collaborate with
members)
• Current network 6 years old, based on ATM mesh
between state and territory networks (RNOs)

Work in Progress
• APL is currently designing a new network for
deployment in January 2004
• Design largely complete
• Commercial negotiations still in progress
• Deployment yet to come

Basic Design
• Dual SDH unprotected links from Brisbane to Perth
• Dual Points of Presence in each capital city along path
• Using MPLS Fast Failover for “protection”
• Burst capacity 2x “protected” link capacity
• Supports IPv4 and IPv6 (unicast & multicast)
• Supports QoS (diffserv)
• Uses MPLS-TE to minimise latency for Voice/Video
over IP (and potentially other real time applications)
• Customers connect via Gigabit Ethernet

Services
• Basic transport of IP packets
• Customers use precedence tagging on a packet to
change QoS, both premium (up) and scavenger (down)
• Premium service used primarily for Voice/Video over IP
applications, e.g. toll bypass & video conferencing
• Voice implemented like an extended PABX
• APL provides MCU in support of Video over IP
• Rapid growth in deployment of Access Grids

Grid Concepts
• “Resource sharing & coordinated problem solving in
dynamic, multi-institutional virtual organisations” (Ian Foster)
– On-demand, ubiquitous access to computing, data, and services
– New capabilities constructed dynamically and transparently from
distributed services
• “When the network is as fast as the computer's internal
links, the machine disintegrates across the net into a set of
special purpose appliances” (George Gilder)
