Caltech and CERN send data at more than 6.25 Gbit/s across 6,800 mls

Arlington (VA) - Setting a new Internet2 land speed record (I2-LSR), members of the California Institute of Technology and CERN sent data at more than 6.25 Gbit/s across 11,000 km, more than 10,000 times the speed of a typical broadband connection.

The new speed record trumps previous record of the open I2-LSR competition, which previously was held also by Caltech and CERN and had reached a reported 5.44 Gbit/s in October 2003, when more than one TByte of data was transferred via IPv6 in less than 30 minutes between Chicago, IL and Geneva, Switzerland.

The new mark is set at an average rate of 6,25 Gbit/s which was sent between Los Angeles and Geneva over a distance of 10,949 km (6804 mls) using IPv4 protocols.

"This new record is of great importance to the future of data intensive Grids such as the Large Hadron Collider (LHC) Computing Grid that CERN, together with its LHC partners around the world, is actively deploying. We are hopeful that new IPv4 and IPv6 Internet2 Land Speed Records will be established this year, bringing us closer to 100 petabit-meters per second marks, or nominal 10 gigabits per second throughputs," said Olivier Martin, Head of External Networking at CERN.

The current record is set at 68,431 terabit-meters per second, which was achieved over a timeframe of about 10 minutes. Details and traffic statistics of the file transfer can be found on the
