Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a networking router that transmits data at nearly 40 gigabytes per second, significantly faster than the previous record for such devices. The researchers say the system could lead to a number of breakthroughs, including the use of cheaper commodity chips in high-performance routers. The software also could serve as a testing ground for new networking protocols.

"We started with the humble goal of being the first to get a PC router to 10 [gigabytes per second], but we pushed it to 40," says KAIST's Sue Moon.

The software, called PacketShader, uses a computer's graphics processing unit to help process packets of data sent across a network. PacketShader could slash the number of physical machines needed to comprise a terabit-per-second software router to one third of what research has previously indicated would be required, says Intel Labs Berkeley's Gianluca Iannaccone.
