SDN-based autonomic CCN traffic management

Content-Centric Networking (CCN) is a novel architecture that has been proposed as a solution for dealing with various problems obsessing the Internet, such as the excessive bandwidth costs that result from peer-to-peer (P2P) traffic and content delivery networks (CDN). CCN names packets rather than end-hosts, and most of CCN's characteristics are the consequences of this fact. However, the current design of CCN has some limitations in traffic control, especially in flow fairness and node-to-node collaboration. To solve this problem, we propose an SDN-based autonomie system as the control plane to supplement CCN traffic management. Correspondingly, in the data plane, we utilize a multiprotocol switch to support CCN protocol, flow-aware content delivery and traffic control. We also discuss the implementation and extension issues, and finally, we demonstrate our hybrid scheme to perform centralized and intelligent traffic management, which provides higher awareness, fairness, and low congestion.
