摘要：
Current researches on content centric networking routing mainly focus on selecting the best routing path from forwarding information base (FIB). The path leads the requests to the server, so only the on-path caches are currently used, which results in low utilization of the in-network caches. More caches can be exploited if more FIB faces are used for multipath routing, but it will bring a lot of redundancies. To solve these problems, a content trace multi-path routing (CTMR) scheme is proposed. In this scheme, Interest packet is sent to the caches along with the traces of the former Data packet. Therefore, the Interest packets are routed to the in-network cache resources before they routing to the server, the utilization of the in-network caches is increased with a little redundancy, while the server load is decreased. Simulation shows that the CTMR decreases the server load about 10% and reduces the mean hops compared with the existing schemes. The cache hit rate in CTMR is increased about 20% relative to the single path routing. The redundancy in CTMR is reduced by more than 10% with the similar cache hit rate relative to the multipath routing.
