  1. AARNet3 George McLaughlin Director, International Developments

  2. 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)

  3. 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

  4. 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

  5. Australia’s Research and Education Networks

  6. Australia’s Research and Education Networks • AARNet3 • GrangeNet • CeNTIE • AARNet/Powerlink North Queensland Network • AARNet/TrandGrid Central NSW Network

  7. 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

  9. 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)
