Abilene Update SC'99 :: Portland :: 17-Nov-99

Outline Goals Architecture Current Status NGI Peering International Peering Multicast

Goals Support very high data-rates –OC-48 in phase 1 Minimize speed-of-light delay Provide Sonet access at over 100 Qwest PoPs Support advanced IP functionality such as multicast and QoS Support advanced applications!

Core Architecture Router Nodes –About 10-15, located at Qwest PoPs –Cisco routers –Out-of-band access, Surveyor Interior Circuits –Qwest OC-48 and OC-12 Sonet –Simple POS between Router Nodes

Seattle Kansas City Denver Cleveland New York Atlanta Houston Abilene Core :: Nov-1999 Sacramento Los Angeles Denver Indianapolis

Seattle Kansas City Denver Cleveland New York Atlanta Houston Abilene Core :: spring 2000 Sacramento Los Angeles Denver Indianapolis Washington

Access Architecture Access Circuit: site to Router Node –OC-3, OC-12 now; OC-48 possible –IP/Sonet or IP/ATM framing Access Node: any Qwest Sonet PoP –Backhaul from Access Node to Router Node viewed as part of Abilene –Local from site to Access Node varies

Abilene Connections :: Nov-1999

Abilene Connections :: now and in process

Summary of Connections Connections –28 now –9 on the way Participants –102 now –27 on the way

NGI Peering Internet2 and federal NGI networks peer at a set of NGI exchanges, or NGIXes –Chicago (same ATM switch as StarTAP) –NASA Ames –Univ Maryland College Park, near DC Other ad hoc connection points also exist

Joint Techs Meeting Miami, Florida, 6-8 December 1999 Joint project of: –Internet2 –NLANR Advanced networking technology and infrastructure consultation

Goals for SC'00 Increase support for native multicast Increase experience with high-speed wide-area TCP –Web100 project beginning Make OC-12 (600 Mb/s) performance ordinary

The Bottom Line for SC'99 The aggressive combination of high- speed computing and high-speed networking is exactly why Internet2 infrastucture, including Abilene, have been built We welcome the challenge to support this!
