University of Arizona researchers and colleagues from nine other institutions are collaborating on the Named Data Networking project to restructure the Internet's architecture. The architectural change should focus on improving performance, security, and usability, says Arizona computer scientist Beichuan Zhang.

The researchers want to develop a system that places a unique marker on the packet of information where the data resides, which will allow specific users to download that data, and then the router can forward the data to other users who request it. This type of system means that the data only travels once, minimizing the wait time for users. "The Internet was built in the early '70s, and the fundamental architecture hasn't changed much," Zhang says. "However, almost everything else has changed. The applications have changed."

The Palo Alto Research Center has already developed open source software that will form the basis for the Named Data Networking project's final system. The research team plans to develop a prototype system within three years, Zhang says.
