A Rewired Internet Would Speed p Content Delivery
Credit: University of Notre Dame
A new networking technique could accelerate video downloads and other forms of Internet content delivery. Content-centric networking, under development at the Palo Alto Research Center (PARC), involves the computer attempting to retrieve content by requesting the content itself by its unique name, instead of relying on machines' Internet protocol (IP) addresses to pass data along. PARC researcher Glenn Edens says the method could lower the cost for transmitting video or other data to large audiences, which should subsequently reduce many services' costs as well as increase reliability by shortening the distance that content travels.
The Internet connections of mobile devices could improve significantly through the new networking model, as switching between wireless access points would not require a new IP address, Edens says.
PARC is making its content-centric networking technology available as open source, and is providing a Web site to help coordinate research across an expanding community that includes academic and corporate research labs around the world. "There are now a couple of deployments at a level that aren't quite production and aren't quite research," Edens notes. However, he says an Internet service provider could implement content-centric networking inside its own network and realize substantial cost savings.
