There were two strategies for the data forwarding in the content-centric networking (CCN): forwardingstrategy and routing strategy. Forwarding strategy only considered a separated node rather than the whole networkperformance, and Interest flooding led to the network overhead and redundancy as well. As for routing strategy inCCN, each node was required to run the protocol. It was a waste of routing cost and unfit for large-scale deployment.This paper presents the super node routing strategy in CCN. Some super nodes selected from the peer nodes in CCNwere used to receive the routing information from their slave nodes and compute the face-to-path to establish forwardinginformation base (FIB). Then FIB was sent to slave nodes to control and manage the slave nodes. The theoreticalanalysis showed that the super node routing strategy possessed robustness and scalability, achieved load balancing,reduced the redundancy and improved the network performance. In three topologies, three experiments were carriedout to test the super node routing strategy. Network performance results showed that the proposed strategy had ashorter delay, lower CPU utilization and less redundancy compared with CCN.
