Net Pioneer Wants New Internet
David Clark, who led the development of the internet in the 1970s, is working with the National Science Foundation on a plan for a whole new infrastructure to replace today's global network.

The NSF aims to put out a request for proposals in the fall for plans and designs that could lead to what Clark called a "clean slate" internet architecture. Those designs, Clark said, could be tested on the National LambdaRail, the nationwide optical network that researchers are using to experiment with new networking technologies and applications.

Two NSF program directors in the agency's Networking Technology and Systems program refused to speak on the record about the $200,000 grant the agency gave Clark to explore his "clean slate" internet idea. Nor would they comment on a broader initiative taking shape at the NSF, of which Clark said his research is a component.

But Clark hinted that the agency is poised to take a leading role in developing new internet technologies.

"There are (program directors) at the NSF who are willing to rally the academic community," said Clark. "They are saying, 'Let's break some eggs.'"

Clark, who served as chief protocol architect for the government's internet development initiative in the 1980s, wants researchers to re-imagine the infrastructure that connects computer users around the world.

The problem with today's internet, according to Clark, is that its 30-year-old design, which allowed for the development of exciting new applications (the world wide web, e-commerce, file sharing, you name it), is now stifling further growth.
