Bandwidth Challenge Results

Posted by samzenpus on from the greased-lightning dept.

the 1st sandman writes "SC2005 published some results of several challenges including bandwidth utilization. The winner (a Caltech led team of several institutes) was measured at 130 Gbps. On their site you can find some more information on their measurements and the equipment they used. They claimed they had a throughput of several DVD movies per second. How is that for video on demand!"

    I love arbitrary metrics..

    Given you might need to serve a few thousand people an hour (or more?), I'd say it's still got awhile to go. Kinda sobering, when you think about it. Shiny discs and station wagons are going to be around for awhile.

      That's whole movies per second they are talking about. So even at only 2 movies per second thats 7200 people to get complete movie downloads per hour.

  2. A chain of airplanes has more throughput by davidwr · · Score: 3, Insightful

    Imagine you "owned" O'Hair Int'l and the Atlanta airport, two of the busiest airports in America.

    Imagine you had as many big planes as possible taking off from each airport and landing at the other every day.

    Imagine they were all filled with hard disks or DVDs.

    Now THAT is a lot of bandwidth.

    Latency sucks though.

    The moral of the story:
    Bandwidth isn't everything.
