The current Internet is based on host-centric networking, and a user needs to\nknow the host address before reaching a data target in the network. The new\narchitecture of information-centric networking (ICN) facilitates users to locate\ndata targets by giving their data names without any information about\nhost addresses. In-network caching is one of the prominent features in ICN,\nwhich allows network routers to cache data contents. In this paper, we emphasize\nthe management of in-network cache storage, and this includes the\nmechanisms of cache replacement and cache replication. A new cost function\nis then proposed to evaluate each cache content and the least valuable content\nis evicted when cache is full. To increase cache utilization, a cooperative\ncaching policy among neighboring routers is proposed. The proper network\nlocations to cache data contents are also discussed in the paper. Experimental\nresults show the superiority of the proposed caching policy than some traditional\ncaching polices.
