Scalable area-based hierarchical control plane for software defined information centric networking

Recently there has been a new emerging trend in integrating Information Centric Networking (ICN) and Software Defined Networking (SDN) together in the future internet research area. Software defined information centric networking (SD-ICN) may face more serious scalability problem in control plane compared with traditional SDN environment due to new features about in-network cache and content-based communication. In this paper, we address the control plane scalability problem from viewpoint of ICN/SDN integration and propose a scalable area-based hierarchical architecture (SAHA) for controller deployment in SD-ICN. The SAHA supports scalable awareness of network resources and content resources, as well as guarantees efficient interest matching and resource adaptation. Simulation experiments under OMNET++ show that the proposed SAHA can achieve good scalability in resource awareness and content-based communication.
