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 12008 routers– Out-of-band access, Surveyor

• Interior Circuits– Qwest OC-48 and OC-12 Sonet– Simple POS between Router Nodes

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

The Abilene Team• Qwest Communications• Nortel• Cisco• Indiana University (NOC)• MCNC and OARnet (ITEC)• UCAID

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

Specific Abilene NGI Peering• vBNS: Chicago and Washington• NREN: Ames and Chicago• NISN: Chicago• DREN: Ames and Chicago• ESnet: Berkeley, Chicago, Atlanta

• Theme: reduce latency in univ-lab paths

International Peering• Focused on non-US advanced R/E

networks• Supports StarTAP exchange point• But also uses other peering locations to

minimize:– latency– cost burden for peer

Joint Techs Meeting• Miami, Florida, 6-8 December 1999• Joint project of:

– Internet2– NLANR

• Advanced networking technology and infrastructure consultation

• www.internet2.edu/html/dec99miami.html

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!
