A survey of the research on future Internet architectures

The current Internet, which was designed over 40 years ago, is facing unprecedented challenges in many aspects, especially in the commercial context. The emerging demands for security, mobility, content distribution, etc. are hard to be met by incremental changes through ad-hoc patches. New clean-slate architecture designs based on new design principles are expected to address these challenges. In this survey article, we investigate the key research topics in the area of future Internet architecture. Many ongoing research projects from United States, the European Union, Japan, China, and other places are introduced and discussed. We aim to draw an overall picture of the current research progress on the future Internet architecture.
