  17. Middleware Challenges • Identify technologies that are scalable and interoperable • Increase deployment of middleware technologies as part of a pre-commercial production environment • Examples: • Distributed storage - I2DSI initiative • Multicast video tools - I2DVN initiative

  18. Engineering Objectives • Deploy a production network to support applications R&D • Establish quality of service (QoS) • Support native multicast • Establish gigaPoPs as effective service points

  19. I2 Interconnect Cloud Network Architecture GigaPoP One GigaPoP Two GigaPoP Three GigaPoP Four “Gigabit capacity point of presence” an aggregation point for regional connectivity

  20. I2 Interconnect Cloud GigaPoPs, cont. University A E.g. vBNS, Abilene GigaPoP One Commodity Internet Connections Regional Network University B University C

  21. Internet2 GigaPoPs

  22. Abilene Project • Provide advanced network testbed • Support Internet2 applications development • Demonstrate next generation operational and quality of service capabilities • Create facilities for network research

  23. Abilene Router Node Abilene Access Node Operational January 1999 Planned 1999 Abilene NetworkJanuary 1999 Seattle Cleveland New York Sacramento Denver Indianapolis Kansas City Los Angeles Atlanta Houston

  24. Abilene Characteristics • 2.4 Gbps (OC48) among gigaPoPs, increasing to 9.6 Gbps (OC192) • Connections at 622 Mbps (OC12) or 155 Mbps (OC3) • IP over Sonet technology • Access PoPs very close to almost all of the anticipated university gigaPoPs

  25. Abilene Schedule - the latest • Fall 1998: Demonstrated network at member meeting, in pre-production at several universities, connected to Chicago switch for STAR TAP • January 1999: Initial group of around 65 members connected in production mode • 1999: Other members connected as mutually planned

  26. For UCAID Members • Involvement in the decisions • Responsive to continuing needs • Driven by member research • Potential for increasing connectivity for all UCAID university members wanting to participate in Research Goals.

  27. Current Priorities • Establish backbone connectivity • Facilitate middleware implementation • Support network research • Identify and develop first phase applications • Build international collaboration opportunities

  28. US Federal Government: Next Generation Internet (NGI) Programhttp://www.ngi.gov • Established in parallel with Internet2 • multi-agency research and development (R&D) program to develop, test, and demonstrate advanced networking technologies and applications • via testbeds that are 100 to 1,000 times faster end-to-end than today's Internet

  29. Internet2 <--> NGI Relationship • Similar technical objectives • Focused on different, but complementary communities • NGI: Federal Mission agencies • UCAID/Internet2: university research and education community • Working to interconnect, make interoperable federal research networks and Abilene

  30. Internet2 <--> NGI Relationship cont’d • Cooperative programs: • NSF High Performance Connections grants: UCAID universities using to connect to achieve Internet2 connectivity • Abilene <-> Energy, NASA network interconnection: being planned to provide high performance access for universities to research labs • Applications: researchers benefit from numerous federal grants that help develop applications

  31. The QBone - What is It? • An interdomain testbed for differentiated services • Goals: • Grow a snowball of interoperable DiffServ clouds • Grow a community of participants • Foster pre-standards interoperability • Collaborate to solve problems and share experiences • Initial participants have been identified

  32. QBone Call for Participation • CFP issued September 25th, 1998 • Proposals due October 16th • Review complete October 30th • Participant Types • Networks • Network Engineering / Advanced Development • Applications and Middleware Developers • Corporate Partners
