Internet speed records set

released May 17, 2005

Internet2 announced on May 4 that two international teams have set Internet2 Land Speed Records (I2-LSR) in the IPv4 and IPv6 categories. As an open and ongoing competition for the highest-bandwidth, end-to-end networks, Internet2 LSR marks represent the rate at which data is transferred multiplied by the distance traveled.

A team from University of Tokyo, the Japanese WIDE Project, Chelsio Communications, Fujitsu Computer Technologies, LTD, NTT Communications, APAN, JGN2, SURFnet, CANARIE, IEEAF, Pacific Northwest Gigapop, StarLight and Universiteit van Amsterdam has set new records in the IPv4 Single-Stream and Multi-Stream categories by transferring 7.21 gigabits of data per second (Gbps) across a network path spanning a distance nearly three-quarters the circumference of the Earth—30,000 kilometers long. The data traversed the WIDE, APAN, JGN2, IEEAF, CANARIE, SURFnet and Abilene networks. Achieving a mark of 216,300 terabit-meters per second (Tb-m/s), the team surpassed the existing single-stream record by over 66,000 Tb-m/s and the previous multi-stream record by over 30,000 TB-m/s.

The team used an "inter-layer coordinating optimization" technology developed by the Data Reservoir project at the University of Tokyo and used 10 Gbps Ethernet adapters with TCP offloading capabilities by Chelsio Communications.

Using the next-generation Internet protocol IPv6, a team from the California Institute of Technology (Caltech) and CERN set a new mark in the IPv6 Single and Multi-Stream categories. The team set the record by transferring 5.11 gigabits of data per second (Gbps) across a network path of more than 14,000 kilometers. The mark of 72,225 Tb-m/s nearly doubled the previous IPv6 mark.

The record was set with the support of the National Center for Data Mining (NCDM), Cisco Systems, and Neterion.
