Internet2 announced that an international team set a new Internet2 Land Speed Records (I2-LSR) in both the IPv6 and IPv4 single and multi-stream categories. This record marks the fourth time a University of Tokyo-lead team has achieved an Internet2 Land Speed record. As an open and ongoing competition for the highest-bandwidth, end-to-end networks, Internet2 LSR awards represent the fastest rate at which data is transferred multiplied by the distance traveled. See related article. For the IPv4 record, a team from the University of Tokyo, WIDE Project, Microsoft Corp., Pacific Northwest Gigapop, JGN2 and other institutions collaborated to create a network path over 30,000 kilometers in distance crossing eight international networks. In doing so, the team successfully transferred data at a rate of 7.99 Gbps which is equal to 239,820 terabit-meters per second (Tb-m/s). For the IPv6 record, a team from the University of Tokyo, WIDE Project, Pacific Northwest Gigapop, JGN2, Chelsio Communications and other institutions created a path over 30,000 kilometers in distance crossing five international networks. The team transferred data at a rate of 6.18 Gbps. Achieving a mark of 185,400 terabit-meters per second (Tb-m/s) - 10.75% more than the previous record. Dr. Kei Hiraki, professor at the University of Tokyo and LSR team leader said, "Through these trials, we are now demonstrating that the performance of IPv6 is almost on par with IPv4. For researchers and scientists around the world, this is a positive indication that IPv6 is now ready to be used in prime time for their high-performance applications."
