A Joint Congestion Control Strategy in POF-Content-Centric Networking

Abstract

CCN (content-centric networking) provides a solution to solve the problem of content acquisition and distribution in the view of network architecture. The finiteness of network resource and unexpectedness of network traffic result in network congestion inevitably. The mainstream implementation of CCN still relies on IP routing, so the study of congestion control scheme in CCN now cannot reflect the value of the research which can only superimpose over the congestion control scheme of IP. POF (Protocol-Oblivious Forwarding) is an extension of the OpenFlow protocol, which can support forwarding packets in any format. We have realized a prototype of CCN using POF. Then a joint congestion control strategy is proposed in POF-CCN. The experimental results show that the strategy can effectively control congestion in POF-CCN.
