The Internet has been a remarkable success, but many in the research community that contributed to its design now point to limitations and vulnerabilities that are stressing its underlying architecture. This has led to a call for new, clean-slate designs, but it is widely acknowledged that a "red flag day" for transitioning to such a new architecture is not realistic. This talk addresses this delima, and shows how wide-area network testbeds, such as PlanetLab and ViNI (and eventually GENI) can provide a platform for continually reinventing the Internet. Larry Peterson is Professor and Chair of Computer Science at Princeton University. He is Director of the Princeton-hosted PlanetLab Consortium and Chair of the planning group for NSF's GENI Initiative. He is also a co-author of the best selling networking textbook Computer Networks: A Systems Approach (3e).* His research focuses on the design and implementation of networked systems. Professor Peterson recently served as Editor-in-Chief of the ACM Transactions on Computer Systems, he has been on the Editorial Board for the IEEE/ACM Transactions on Networking and the IEEE Journal on Select Areas in Communication, and he has served as program chair for SOSP, NSDI, and HotNets. Peterson is a Fellow of the ACM. He received his Ph.D. degree from Purdue University in 1985.
