Network Adapter Keeps Talking While a PC Is Asleep

Posted by timothy on from the would-make-me-feel-better-about-keeping-a-server-on dept.

Al writes "Researchers at Microsoft and the University of California, San Diego have developed a network adapter that lets a computer enter sleep mode without disrupting the network connection. The adapter, dubbed Somniloquy (meaning to talk in one's sleep), consists of a gumstix running embedded Linux, 64MB of RAM and a 2G SD memory card, connected via USB. The adapter keeps the network connection going and the researchers have also developed a simplified IM client and bittorrent client that carry out more complicated tasks autonomously, only waking the computer if, for example, an actualy IM is received or a download is completed."

  1. Mainframe architecture revisted ... by golodh · · Score: 4, Interesting
    It's funny how today's PCs continue to take architectural queues from earlier mainframe and minicomputer designs.

    Remember when your IBM mainframe had an array of special I/O processors? Well, the bus arbitrator on your motherboard looks suspiciously like one of those. And remember when disk arrays because "smart"? Well ... just looks at the electronics on the average SATA IDE drive and you'll see what I mean. It manages the hardware, and you only talk to the drive's on-board controller, never to the drive itself.

    And now this network controller. Pardon me, I mean network card.

    Is this scary technology? Now your system can become a true zombie on a botnet while asleep. Couldn't a virus/worm just wake your system up and infect it?
