Mobility management scheme based on Software Defined Controller for Content-Centric Networking

Content-Centric Networking (CCN) is a promising architecture in the current Internet, and has the potential to be a revolutionary innovation in the future Network. CCN has not broken away from the binding of physical location and content name, however, the content source mobility will remain a great challenge for CCN. In addition, the problem of the large overhead incurred during the handoff requires urgent resolution. Software Defined Networks separate the control plane from the data plane to reduce the overhead of the signaling exchange and routing update processing. Hence, we present a method that uses a software defined technique to realize mobility management for CCN. In this work, we propose a mobility management scheme based on a software defined controller. The key point of Software Defined Networking is that the routing table in each content router can be rewritten, allowing the latest relationship between the location and content name to be updated on the network. Numerical simulations show that our scheme provides better performance than existing techniques in terms of total handoff overhead.
