Carnegie Mellon University is leading a project named for the long-range goal of building a clean-slate Internet that will provide 100 mega-bit-per-second connections to 100 million US homes. AT&T Labs-Research; the University of California, Berkeley; the Center for Appalachian Network Access; Fraser Research; the Internet2 Project; the Pittsburgh Supercomputing Center; Rice University; and Stanford University are also participating in the 100 x 100 Clean Slate Project. Economists, security and networking experts, network operators, andpolicy specialists are contributing to the project, designed to develop protocols and create an Internet that will offer large amounts of band-width and be economically self-sustaining, secure, and manageable. They will address issues such as network architecture, management,security, reliability, scalability, and economics. The National Science Foundation has provided $7.5 million in fundingfor the project, which will entail fundamental research, proof-of-concept implementations, and testbeds that could be used in further studies.
