A survey on future internet architecture

Internet has become as a social infrastructure. The current Internet architecture based on TCP/IP is faced with many challenges. This fact makes the clean-slate design of future Internet architecture be a hot research topic. This paper analyzes the essential problems that are inherent in the current Internet architecture, including scalability, mobility, security and controllability, and comprehensively introduces the existing research works on the future Internet architecture such as the scalability-oriented architecture, the mobility-oriented architecture etc. Considering experiment-based validation is an important means for the research of future Internet, this paper further presents the development of programmable virtual routers and the corresponding testbeds. Finally, open issues on the future Internet architecture design are discussed.
