The joint research as preparatory work is intended to foster the following major research topics: architectural re-design of the Internet, involving new models for naming, addressing and routing to overcome serious limitations of the current Internet. Working towards a decentralized and information-centric architecture based on the principle of self-organization will be of major interest. Furthermore, security related research with focus on denial-of-service, network availability and resilience will provide a complementing focus. These long-term goals will only be achieved if based on thorough testing in a realistic environment of global scope. Starting with the current PlanetLab overlay infrastructure a more generic testing facility will be investigated. The research on the testing facility is intended to spawn or to feed into other European and US related research initiatives.
