abilene october 2002
Abilene – October, 2002
  • IP-over-DWDM (OC-192c) and IP-over-SONET backbone (OC-48c)
  • 50 direct connections (OC-3c  10-Gbps)
    • 4 (soon 6) OC-48c & 1 Gig Eth connections
    • 2 10-Gbps (10 Gig Eth) connections pending
      • OC-192 SONET also supported

  • Juniper T640 routers selected for backbone
    • 10/11 next generation router nodes in place; 12th location pending
      • 2 racks in each location (Juniper T640 router & 4 measurement servers)
      • OC-48c SONET interconnects to Cisco 12008 routers
      • Very pleased to date with new router performance and interoperability with 1st generation backbone
  • 10-Gbps backbone  deployment has started this Fall
    • Transcontinental 10-Gbps ’s: 6 ’s connected to network
      • DC-NYC-Chicago-Indy-KC-Sunnyvale CA-Los Angeles

  • Astronomers collect data about a star from many different earth based antennae and send the data to a specialized computer for analysis on a 24x7 basis.
  • VLBI is not as concerned with data loss as they are with long term stability.
  • The end goal is to send data at 1Gb/s from over 20 antennae that are located around the globe.


Successfully ran 788 Mbps sustained test between sites in U.S. Working on prototype experiment to test their ability to run data to Europe and Japan.
