Slide 1: Australian Networks status report
John Barlow Advanced Communication Services Coordinator GrangeNet
Slide 2: AARNet
• Currently AARNet2 is a 155M ATM backbone with 34M and 155M tails
– Tunneled IPv6; QoS; IPv4 multicast; VoIP; H.323 MCU; full netflow logging; single POP
• About to build AARNet3, a mixed 622M / 2.5G PoS backbone with GbE tails
– Native IPv6; IPv4; multicast; VoIP; H.323 MCU; SIP; redundant POP; jumbo/large MTU.
Slide 3: Australian Research and Education Network
Slide 4: GrangeNet
• Government funded network (3 years, Aus$14,000,000) • Multiple 2.5G PoS backbone with GbE tails
– Native IPv6; IPv4; IPv4 multicast; MTU 9000; soon QoS; soon IPv6 multicast.
• Mostly university but also any research group/company • Access grids a prime reason for connecting (previous Australian links have limited capacity and 4 to 8 Mbps congests them).

Slide 8: CeNTIE Positioning
• Breakout of thought ruts: aim to make available today technologies and business practices that may be 3-5 years away • Applications have not caught up with advances in networking • User heightened focuses NOT technology focused: allow the user to concentrate on what they are trying to do. • Industrial and Research Focus – four user communities with advanced needs which are poorly met at present, and point to the future.
Slide 9: CeNTIE Technology Summary
• Extensive dark fibre in Sydney and Perth metropolitan areas. Partitioning by glass, wavelength, VLAN and later MPLS. • End users have Gigabit Ethernet (10GE capable) with Ethernet switches as core. VLANS and CWDM are used in MANs, evolving to MPLS. • Long haul is 10Gbit/s DWDM wavelength using solitons from Melbourne to Perth • Interconnect with GrangeNet using MPLS tunnels, gives coverage on east coast. • network research in QoS, edge services, advanced layer 2 services and optical switching.
Slide 11: MNet
Government funded network (3 years, Aus$5,000,000) • Wireless network over the city of Adelaide • 3G phone testbed • Mobile phone (SMS) services http://www.mnetcorporation.com/
Slide 12: AREN
• Government funding for a research network in Australia • Aus$42,000,000 over 2 years Currently in discussion!

Slide 14: Australian Research and Education Network
Slide 15: AARNET’s International Network
Slide 16: Services
• Want to:
– – – – peer VoIP network with others experiment with ENUM start using SIP Get universities running IPv6 natively
• Making progress with access grids • Good success with
– VoIP (H.323) – video over IP – native IPv4 multicast on most universities
