Network status aware routing in content-centric network
Yueping Cai, Jun Liu · DOAJ (DOAJ: Directory of Open Access Journals) · 2016
To improve the efficiency of content delivery and to reduce the network overhead of content centric network (CCN),a network status aware routing(NSAR)mechanism was proposed.NSAR utilized data packets from the content server nodes to collect network statuses.The forwarding probability of the matching ports of the nodes on the path would be updated according to the network statuses.The subsequent interest packet forwarding would be based on the updated forwarding probability.Therefore the content delivery efficiency would be improved.Simulation results show that NSAR can effectively reduce the average delay of content requests and the number of packets in network as well as the network bandwidth overhead compared with the traditional routing algorithm in CCN.
