Despite its obvious success, the Internet suffers from end-to-end performance and availability problems. We believe that intelligent routers at key access and interchange points could improve Internet behavior by actively managing traffic. We describe the inefficiencies in routing and transport protocols in the modern Internet. We are constructing a prototype, called Detour, a virtual Internet, in which routers tunnel packets over the commodity Internet instead of using dedicated links.
