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


Australia’s Research and Education Networks


Australia’s Research and Education Networks

• AARNet3• GrangeNet• CeNTIE• AARNet/Powerlink North Queensland Network• AARNet/TrandGrid Central NSW Network


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)
