Testbed deployment status

• Very unique multi-vendor testbed with layer2 and
  layer 3 capabilities,
• in effect, a distributed transatlantic Internet
  Exchange Point.
• Very interesting results already achieved
• Triumf-CERN 2GigE lightpath demo (disk to disk)
• Terabyte file transfer (Monte Carlo simulated
  events)
• Single stream TCP/IP (with S.Ravot/Caltech
  patches)
• 8 Terabytes in 24 hours (memory to memory)
• IST2002 Demos
• SC2002 Demos Records
