Les Cottrell – SLAC
Prepared for the CHEP03, San Diego, March 2003
Partially funded by DOE/MICS Field Work Proposal on Internet End-to-end Performance Monitoring (IEPM), by the SciDAC base program.
One Terabyte transferred
in less than one hour
On February 27-28, over a Terabyte of data was transferred in 3700 seconds by S. Ravot of Caltech between the Level3 PoP in Sunnyvale, near SLAC, and CERN.The data passed through the TeraGrid router at StarLight from memory to memoryas asingle TCP/IP stream at an average rate of 2.38 Gbps (using large windows and 9KByte “jumbo” frames).This beat the former record by a factor of approximately 2.5, and used the US-CERN link at 99% efficiency.
