Internet2 Speed Record: Four Times As Fast

Looking for faster downloads? Try a sustained transfer of 101 gigabits per second between Pittsburgh and Los Angeles on Internet2. That's the speed hit by an international team lead by Caltech last week, the second year in a row the "High Energy Physics" team has won the Supercomputer Bandwidth Challenge.

101 gigabits per second is more than 4 times as fast as last year's record of 23.2 gigabits per second!

The heart of the new effort is the new FAST congestion control algorithm for high performance TCP, developed by the Caltech Netlab team. The effort also involved an powerful collection of hardware, including seven 10 Gbps links to Cisco 7600 and 6500 series routers, and four dedicated wavelengths of National LambdaRail. (The Caltech press release details all the hardware used in breaking the Internet2 Speed Record.

According to Caltech, the team includes the California Institute of Technology and includes as partners the Stanford Linear Accelerator Center (SLAC), Fermilab, CERN, the University of Florida, the University of Manchester, University College London (UCL) and the organization UKLight, Rio de Janeiro State University (UERJ), the state universities of São Paulo (USP and UNESP), the Kyungpook National University, and the Korea Institute of Science and Technology Information (KISTI).

The Caltech press release on the new Internet2 Speed Record is full of technical details.
