  1. AARNet3The Next Generation of AARNet

  2. Background to AARNet • AARNet Pty Ltd (APL) is a not for profit company owned by 37 Australian Universities and the Commonwealth Scientific & Industrial Research Organisation (CSIRO) • Operates a national network providing commodity and research Internet access to members and clients • Clients include Defence Science and Technology Organisation (DSTO), National Library of Australia, Australian Institute of Marine Science • Current network deployed in 1997, based on ATM mesh between state and territory networks (RNO) • Also operates a STM-1 ring to the USA (Hawai‘i and Seattle) on Southern Cross, primarily for research but some commodity via Pacific Wave • Currently buys commodity access at each RNO from Optus or Telstra

  3. Design Issues • Redundancy & Resilience • Support for IPv4 and IPv6 • unicast and multicast • Traffic Accounting and Monitoring • End to end performance measures • Support QoS (diffserv) • Support for large traffic flows, jumbo frames

  4. Redundancy & Resilience • Dual points of presence (POP) in major capital cities • Diverse, dual unprotected national links • Will use MPLS Fast Reroute for protection • Provides ability to burst above capacity • Use single metro dark fibre pair to connect intra city POP sites • Creates rings between cities • Provides opportunity for members and customers to build diverse, redundant connections to AARNet

  5. Australian Network

  6. 10Gbps Backbone • Provided on the “Nextgen Networks” network • Two fibre pairs on each path • STM-64 service provided on first pair for inter capital trunks • Second pair may be lit with CWDM to allow Gigabit Ethernet drop off to regional members, other solutions to be considered • Member must provide tail to the regional network

  7. Member Connections • Diverse connection to each POP • Two diverse, independent links, one to each POP • Dual connection connecting each POP • Two links over same infrastructure to single POP • AARNet trunks one link to the second POP though switches • AARNet provided diversity • Single link to one POP, AARNet provides LAN linking both AARNet POP sites and the member

  8. Connections through the GigaPOPs

  9. Trans Pacific Transmission • “SX TransPORT” - Dual STM-64 (10Gbps) • Hawai‘i - Manoa and Seattle (Abilene, CA*net 4) • Los Angeles (Abilene, CENIC, CUDI) • Look to add Mauna Kea to Los Angeles path later • Dual STM-4 (622Mbps) for commodity Internet • PAIX Palo Alto (Silicon Valley) • Los Angeles • Add drop offs to existing STM-1’s (155Mbps) • University of South Pacific, Fiji • Possibly Auckland, New Zealand • Connects to 155Mbps path to Tokyo from Hawai‘i

  10. AARNet’s Pacific Ocean links

  11. Equipment • Core Router • 40Gbps capable • Redundant power but not CPU • Packet over SDH to STM-64 (roadmap to STM-256) • Gigabit and 10 Gigabit Ethernet • Core Switch • Pure L2 switching • Fast, Gigabit and 10 Gigabit Ethernet only • Member Edge and POP based “Legacy” routers • 3 x Gigabit Ethernet (Member, POP “A”, POP “B”) • 1 x Fast Ethernet dedicated to flow accounting • Capability to handle legacy (slow) interfaces

  12. Backbone Routers - Procket 8812 • 22RU (95.3 x 44.2 x 64.8 cm) • 12 Line Cards • 48 Media Adapters (MA) • Route Processor • Procket developed System Control Chip • 500MHz IBM Power PC • 2GB main memory • 512MB Compact Flash (system program storage with redundant images) • 20GB Hard Disk Drive (system log files) • 960Gbps 1.2Bpps • 1 Port STM-64 MA • 1 Port 10Gigabit Ethernet MA • 10 Port Gigabit Ethernet MA • 8 Port STM-1/STM-4 MA

  13. Pro/8812 under test • Sitting in the Nextgen node room in Adelaide • Testing the STM-64 circuit between Adelaide and Perth • 32Kbyte Packets ‘back-to-back’ at 10Gbps

  14. Core Backbone Switches - Cisco 6509 • 20 RU (84.4 X 43.7 x 46.0 cm) • 9 Slot Chassis • Supervisor 720 • 720 Gbps • 30Mpps Centralized, up to 400 Mpps for CEF720 interface modules equipped with dCEF (DFC3) or aCEF daughter cards • 4 port 10 Gigabit Ethernet • 48 port 10/100/1000 UTP based Ethernet • 24 port SFP Gigabit Ethernet • Potential for service modules later

  15. Edge Routers - Cisco 7304 • 4-RU (10cm) compact chassis • 4-slot modular system • Network Equipment Building Standards (NEBS) Level 3 compliance • NPE-G100 Processor • Three onboard Gigabit Ethernet ports • 1 GB of Synchronous Dynamic RAM (SDRAM) • 256 MB of removable Compact Flash memory • Better than 1 mpps processing performance • Redundant power supplies • Front-to-back airflow for optimal cooling

  16. IPv4 and IPv6 • Native IPv4 and IPv6 (Dual Stack) network • Unicast and Multicast for both IPv4 and IPv6 • EFT IPv6 Multicast (initially intra-domain only) • Line rate performance for IPv4 and IPv6 • Peering to both R&E and Commodity Internet w/ IPv6 • Hexago IPv6 Migration Broker to aid member and client IPv6 deployment • DNS, AARNet Mirror and USENet News accessible over IPv4 and IPv6 • IPv6 Performance Measurement • IPv6 Flow Records? • Jumbo frames, 9000 byte

  17. Some Issues • End to end performance measures • Desire to measure performance from member site • Provide connectivity reports on core services • Support QoS (diffserv) • Need to support VoIP and VideoIP traffic • Possibly introduce scavenger service • Support for large traffic flows, jumbo frames • Support for EVERYTHING with IPv6?

  18. Services • DNS Cache and Secondary Servers • Usenet News • Hexago IPv6 Migration Broker • DDoS Detection and Mitigation • Investigate appliances • Interest in automatic detection and filtering • Locate next to transit (and peering) links • IPv6 DoS/DDoS? • AARNet Mirror • VoIP Gateways • NLANR and/or RIPE Test Traffic Measurement

  19. Current Status (1) • National Transmission • Confirmation of POP sites • Testing STM-64 circuits • Build new GigaPOP sites • Obtain fibre between GigaPOPs and COs • Solution for Tasmania and Northern Territory • International Transmission • Planning progressing with US partner organisations on connecting “SX TransPORT” • STM-4 to Palo Alto should be enabled during February • Direct Asian links dependant on available funds and member demand

  20. Current Status (2) • Commodity Internet Transit • Access Commodity Internet in Palo Alto • Connected to the PAIX fabric • Obtain transit from MCI/UUnet and NTT/Verio • Commodity IPv6 Transit! • Peer with other organisations at PAIX • Add second commodity POP in Los Angeles • Need to determine • data centre location • backhaul from Morro Bay (San Luis Obispo) • Will use the same transit providers as at Palo Alto

  21. Current Status (3) • Peering • Developing national and local (state) policies • A consideration for POP site location • Regional links • Investigate CWDM options • Possibly issue another RFP • Priorities are: • inland Sydney/Brisbane via the telescopes • coastal Sydney/Brisbane route • Sydney to Albury

  22. IPv6 Migration Broker (1) • What… • Hexago IPv6 Migration Broker • http://broker.aarnet.net.au/ • Tunnel Broker used by FreeNet6 • User setup for 6in4 tunnels, via web form • allocations from AARNet’s 2001:388::/32 address space • Can be used just for end systems • But can also assign prefix for local LAN • No routing functionality, static routing only • Open access but targeted to “local”, Australian community, not just AARNet members & clients

  23. IPv6 Migration Broker (2) • Why? • Members & clients are not ready to fully deploy IPv6 across their network but some interest within their organisation • Some common firewalls, eg PIX, don’t support IPv6 • Tunnel allows traversal of firewalls • But doesn’t provide firewall function unless end point can do it

  24. IPv6 Migration Broker (3) • Experience… • Most configure account but don’t configure tunnel • Some setup tunnel but for whatever reason only use it for a short time… • Perhaps just looking at the Kame :-) • Maybe forgot to add to startup • Small number of users permanent fixture

  25. Current IPv6 Activity • Major IPv6 Transit Links • APAN-JP • Abilene • Native IPv6 connection • Australian National University, Canberra • Permanent IPv6 Tunnels to: • 9 AARNet Members • 4 Commercial ISPs / Carriers • APNIC • New Zealand • Public 6to4 Relay • Migration Broker

  26. IPv6 Activities • AARNet’s IPv6 Migration Broker • http://broker.aarnet.net.au/ • Requires TSP software • IPv6 Forum – Australian Chapter • Mike Biber, Chair AARNet IPv6 Working Group • Promote awareness of IPv6 in Australia • IPv6 Tutorials in each State and Territory – John Barlow • IPv6 Research, e.g. Monash University • http://www.ctie.monash.edu.au/ipv6/ • AARNet IPv6 interface stsistics • http://ipv6.broadway.aarnet.net.au/mrtg/ipv6/ • Seek out and deploy IPv6 peering in Australia
