  • 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
      • First  outage (3.5 hours): fiber cut in NYC
      • ITEC network performance validation test: 8 Gbps of 2-way traffic (v4 and v6 mix) transmitted without loss or reordering – Sunnyvale to San Diego
next generation abilene more
Next Generation Abilene – more
  • Incremental, non-disruptive transitionUpgrade Schedule Overview
    • Aug/Sep – New backbone routers installed

VLBI - Very Long Baseline Interferometry
  • 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.

Interesting:

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.
