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


Outline
Outline

  • Goals

  • Architecture

  • Current Status

  • NGI Peering

  • International Peering

  • Multicast


Goals
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
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 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




Summary of connections
Summary of Connections

  • Connections

    • 28 now

    • 9 on the way

  • Participants

    • 102 now

    • 27 on the way

Ngi peering
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

SHared

circuit to the exchange point

tc

: circuit also serving as Tail Circuit for some customers

JETnet

: connected to the exchange point

pto

: Peering Traffic with Others (non-

JETnets

) goes on the same circuit

JETnet

: plan to connect to the exchange point

temp: Temporary peering until a nearby NGIX is established

JETnet

: no current plan to connect but maybe desired

Specific abilene ngi peering
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
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
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
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 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!
