Presentation Transcript

  1. AARNet The Future Jonathan Potter Executive Director

  2. AARNet and the AREN • The Higher Education Bandwidth Advisory Committee (HEBAC) Report • $42.5m over two years • The Australian Research and Education Network (AREN) • The AREN Advisory Committee (ARENAC) • The AREN Management Company (ARENMC)

  3. Partnerships • Transgrid • Powerlink • Electricity • Gas • Rail • Other Utilities • 2nd Tier Telecommunications companies

  4. AARNet – The AREN • Increased network capacity and a new architecture that enables applications such as video over IP, and high speed collaboration • Comparable with R&E networks in the US and Europe • Link with Australian high speed and experimental networks • GrangeNet • Centie • Link with the global high speed and experimental networks • Provide educational & teaching links with Asia • No dependence on a single internet supplier

  5. AARNet – The AREN (2) • Internet traffic purchased in the US and reticulated over APL links in Australia • Negotiate Peering Strategies with other ISPs • Provision of information storage on the net to save money, increase ease and speed of access • Replace key equipment at each aggregation point (PoP) (Two PoPs in each capital except Hobart and Darwin)

  6. AARNet – The AREN (3) • Provision of an APL managed router at each member’s site(s) (To be negotiated with Members) • Guaranteed end to end measured service delivered to each member’s site. • Wavelength research capacity to the US linked with GrangeNet and possibly Centie (subject to suitable agreement with Government funding sources)

  7. Charging Issues • No initial reduction in charges but increasing reductions as the Network usage increases. • Review of charging system including subscription models and revised R&E international charging. • Differential charging for types of traffic and lower rates for members to be explored

  8. Operational Issues • APL support for the AREN Advisory Committee • APL forming the AREN Management Company for the control of AREN funds supplied by DEST • AARNet Acceptable Use Policy to be based on what is needed by the owners, financially viable and legal • Provision of increased services and content to the research, education, health, government and cultural communities • Enhance APL’s position in the development of the Internet in Australia through arrangements with other service providers to reach a wider user base

  15. AARNet3 DesignAn Update on ProgressQUESTNet 2003 Don Robertson Deputy Executive Director

  16. Acknowledgement • Slides from yesterdays workshop on Connecting Sites to AARNet and GrangeNet • Thanks to Mark Prior

  17. Disclaimer • No Transmission or Equipment Vendors have been selected • So commercial negotiations are yet to commence • No details on vendors will be available until after commercial negotiations are completed • This is a design discussion only

  18. RFP Team • Mary Fleming (chair) • Business Development • Don Robertson • Deputy Executive Director • George McLaughlin • Director - International Development • Steve Maddocks • Network Operations Manager • Mark Prior • Network Architect

  19. RFP Process • Issued on 25 February 2003 • Closed on 21 March 2003 • Received 25 respondents • Wide variety of responses • Some covered whole of RFP • Some very specialised • RFP Team divided task • Domestic Transmission • International Transmission • Internet Transit • Other issues

  20. Domestic Network

  21. Domestic Transmission • Conventional National ISP design, following underlying transmission paths • Redundant and Diverse Trunks • STM-16 (2.5Gbps) Loop (MEL/CBR/SYD) • STM-4 (622Mbps) BRI/SYD • STM-4 (622Mbps) PER/ADL • STM-4 (622Mbps) ADL/MEL • E3 (34Mbps) ADL/ASP • E3 (34Mbps) ASP/DRW • E3 (34Mbps) MEL/HBT

  22. Dual Capital City POP

  23. Interconnection of intra city POPs • Canberra, Melbourne & Sydney • 10 Gigabit Ethernet connection from router to router, through switches • Adelaide, Brisbane & Perth • 10 Gigabit Ethernet connection between switches • Gigabit Ethernet between router and switch • Alice Springs, Darwin & Hobart • Single POP only

  24. Equipment • Core Router • 10Gbps capable • Redundant power but not CPU • Packet over SDH to STM-64 • Gigabit and 10 Gigabit Ethernet • Core Switch • Pure L2 switching • Fast, Gigabit and 10 Gigabit Ethernet only • Member Edge and in POP “Legacy” routers • 3 x Gigabit Ethernet • Capability to handle legacy (slow) interfaces • Member edge router provides flow accounting and guaranteed quality of service

  25. Traffic Accounting • Still flow based • Moved to edge, on member’s site, due to scaling issues • 1RU server • Redundant (emergency) feed to central collector • Central reporting server

  26. DDoS Mitigation • Investigate appliances • Interest in automatic detection and filtering • Locate next to transit (and peering) links

  27. 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 POPs and the member

  28. Member Connections • One or more AARNet supplied and managed edge routers • No firewall functionality, a member responsibility • Member provides “last mile” link between institution and POP • What technology will the members need? • Gigabit Ethernet over metro fibre preferred • Managed Ethernet service • E3 Microwave • Something else? • Will members dual home to both POPs? • If so, how?

  29. AARNet POP Requirements • Space for 4 consecutive 600x900 45RU racks • Individually locked racks or located in private, locked caged area • False floor with underfloor air-conditioning • VESDA • Fire suppression systems, such as FM-200 or Inergen • Dual, redundant AC power feeds to each rack • Backup AC power, with uninterrupted transition between mains and generator • 24x7 secure access • 24x7 “remote hands” for basic hardware changes • 2 PSTN lines • Unrestricted access for any APL nominated carrier • Accessible via multiple carriers over diverse paths

  30. Intra city POP Requirements • Power supply diversity, each POP fed by different sub stations • Availability of diverse fibre paths between POP sites • Physical separation of at least 0.8km

  31. AARNET’s International Network

  32. International Transmission • Dual STM-4 (622Mbps) for commodity Internet transit • San Jose (Silicon Valley) • Los Angeles • Potential for Research STM-64 (10Gbps) • Hawai’i • Seattle (Abilene, CA*net 4) • Los Angeles (Abilene, CENIC, CUDI) • Potential for STM-1’s (155Mbps) to Asia • Tokyo • Singapore

  33. Current Status • National Transmission: • Reviewing final responses from suppliers • Further meetings with potential suppliers next week • Initial POP equipment RFQ closed, responses reviewed and further details sought • Need more detail on exact requirements before going to “best and final offers” • Evaluating potential POP sites

  34. Current Status • International Transmission • On hold, pending further discussions with the Commonwealth government regarding funding for the 10Gbps wavelength • Asian links dependant on available funds and member demand

  35. Current Status • Commodity Internet Transit • Currently seeking information on a transition phase • Plan to obtain transit within Australia initially • Migrate to San Jose and Los Angeles once international transmission in place

  36. Current Status • Peering • Developing national policy • A consideration for POP site location • Regional links • Awaiting outcome of national transmission • AARNet Mirror • Still in queue

  37. Design QuestionsMember Site • What type of service will members use? • Will member dual home on diverse paths? • Will member require dual edge routers? • Will member retain their own border router? • Do members have a firewall appliance? • Netscreen, PIX, Watchguard, SonicWall, … • Is it in a dual, fail over configuration? • Will it connect directly to AARNet edge router? • Routing functionality? • OSPF, RIPv2, BGP, …

  38. Design QuestionsMember Site • NAT? • Please say no :-) • IPv6 support? • Native or tunnel to AARNet tunnel broker? • Multicast? • Jumbo frames? • Does campus infrastructure support it? • Connection to Grangenet or CeNTIE • Directly from member site? • Indirectly via AARNet POP? • Other connections?
