IO ERROR writes: Internet2 researchers broke their own previous speed record using a modification to TCP to reach 9.08 Gbps over a 20,500 mile network path. 'The team surpassed the current IPv4 records, proving that IPv6 networks are able to provide the same, if not better, performance as IPv4,' said an Internet2 announcement issued Tuesday. University of Tokyo led the research team, and was supported by NTT Communications and network operators from the Japanese Widely Integrated Distributed Environment, the Japan Gigabit Network 11, the Netherlands' SURFnet, Canada's CANARIE and the Pacific Northwest Gigapop. The former record of 8.80 Gbps over 20,500 miles was set in February 2006 using IPv4.
