1. DataTAG Project update
HICB meeting,
13 October 2002, Chicago
Olivier Martin - CERN

2. Project focus Interoperability between European and US Grids (WP4)
Grid related network research (WP2, WP3)
High Performance Transport protocols
Inter-domain QoS
Advance bandwidth reservation
Interoperability between European and US Grids (WP4)
GLUE
N.B. In principle open to other EU Grid projects as well as ESA for demonstrations

4. Status Part of the Amsterdam-Chicago-Geneva “wave triangle”
2.5 Gbps transatlantic lambda between CERN (Geneva) and StarLight (Chicago)
Circuit in place since August 20
Part of the Amsterdam-Chicago-Geneva “wave triangle”
Phase 1 with Cisco ONS15454 layer 2 Muxes (August-September – iGRID2002)
Phase 2 with Cisco 7606 routers (October)
Phase 3 with Alcatel 1670 layer2 Muxes (November)
Also extending to the French optical testbed VTHD (2.5Gps to INRIA/Lyon)
And through VTGD to EU/ATRIUM
And, of course, to GEANT

6. 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 2Gbps 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)
