    Internet2 speed record

    New Internet2 land speed record set
    Howard Dicus Pacific Business News

    The speed limit just got faster in cyberspace U.S. and Dutch engineers have sent the equivalent of two DVDs 6,800 miles in less than one minute.

    They sent 6.7 gigabytes between Amsterdam and California at 923 megabits per second 3,500 times faster than your broadband connection at home. The peak speed, and the new record, was 9,891.60 terabit meters per second.

    "We are approaching network performance which, for the first time, will enable international scientific collaborations to share and access the massive databases that are nowadays common in fields such as particle physics, astronomy, biology, seismology," said Cees de Laat of the University of Amsterdam, one of the researchers involved in the test.

    It's the latest in a series of Internet land speed records in a competition being held by members of Internet2, a parallel Internet that connects hundreds of public and private science and technology centers.

    The University of Hawaii is part of Internet2 and its chief information officer David Lassner is active on the committees that manage it.

    New technologies and ideas are tested on the Internet2 and the ones that work best can be expected one day to migrate across to the "consumer Internet" or "legacy Internet" as Internet2 researchers call the Web that the rest of us use.

    One of the most important current uses of Internet2 is to send real-time data from the Keck Observatory atop Mauna Kea to astronomers on the mainland. They also get simultaneous data from a telescope atop the Chilean Andes, and the two datastreams provide what amounts to binocular vision of distant stars. Without Internet2 it wouldn't be possible because of the speeds and volumes involved.

    The new land speed record, announced Monday but actually done weeks before during a technical conference, involved engineers from Caltech, the Stanford Linear Accelerator, the University of Amsterdam and a Dutch physics institute. They used the advanced networking capabilities of TeraGrid, StarLight, SURFnet, NetherLight, and wide area optical networking links provided by Level 3 Communications and by Cisco.

    The researchers said the test shows that the protocols that support the regular Internet are sufficient for volumes and speeds necessary for advanced physics experiments that require data transfers across large distances. It has been decades since those protocols, which break up datastreams into tiny packets of data that get reassembled at the other end of a transmission, were devised.
