© Copyright AARNet Pty Ltd 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)

© Copyright AARNet Pty Ltd 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

© Copyright AARNet Pty Ltd 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

© Copyright AARNet Pty Ltd 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
