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.

    Or Libraries of Congress per second. DVDs per second isn't a useful rate, unless you're transferring lots of DVDs in a series - which few people do. The much more interesting bandwidth unit is "simultaneous DVDs", multiples of 1.32MBps, 1x DVD speed (9x CD speed). 130GBps is something like 101KDVD:s, which means an audience could watch 101 thousand different DVDs on demand simultaneously over that pipe. That's probably enough for most American cities to have fully interactive TV.
