Caltech Booth 428. SLAC/FNAL Booth 302
Official UltraLight Page with full details of our winning entry.
We reached a peak speed of 151 Gbits/sec aggregated across the waves connected to the CACR and SLAC/FNAL Booths. We sustained > 100Gbits.sec for more than four hours, equivalent to transferring over one PetaByte in a day. The network traffic was generated by a rich mixture of real physics applications, including bbcp, xrootd, Clarens, Root, gridftp and dCache transfers. We used FAST TCP predominantly, as well as vanilla TCP stacks.
Harvey's presentation, giving full details of the event and partners, is here (~10MByte).

entry will demonstrate high speed transfers of physics data between host labs
and collaborating institutes in the USA and worldwide. Caltech and FNAL are
major participants in the CMS collaboration at CERNís Large Hadron Collider (LHC).
SLAC is the host of the BaBar collaboration. Using state of the art WAN
infrastructure and Grid-based Web Services based on the LHC Tiered Architecture,
our demonstration will show real-time particle event analysis requiring
transfers of Terabyte-scale datasets.
We propose to saturate at least fifteen lambdas at Seattle, full duplex (potentially over 300 Gbps of scientific data).
The lambdas will carry traffic between SLAC, Caltech and other partner Grid Service sites including UKlight, UERJ, FNAL and AARnet.
We will monitor the WAN performance using Caltech's MonALISA agent-based system. The analysis software will use a suite of Grid-enabled Analysis tools developed at Caltech and University of Florida. There will be a realistic mixture of streams: those due to the transfer of the TeraByte event datasets, and those due to a set of background flows of varied character absorbing the remaining capacity. The intention is to simulate the environment in which distributed physics analysis will be carried out at the LHC. We expect to easily beat our SC2004 record of ~100Gbits/sec (roughly equivalent to downloading 1000 DVDs in less than an hour).
