In-network caching scheme is one of the key technologies of Content Centric Networking (CCN). In some existing CCN caching schemes, the dynamic information of cache state and load condition are not fully considered so that the differences of cache state between nodes cannot be reflected accurately, which affects the reasonability of caching decision. In this paper, a Cache Pressure Based Selective Caching Scheme (CPBSC) was proposed. In this scheme, the cache occupancy rate and cache replacement rate were used to estimate the cache pressure of node. According to the cache pressure and content popularity, the caching nodes were rationally selected. Meanwhile, the content replacement is implemented based on the cache value of content which is evaluated by the content request rate and the residual time to live of Interest packet. Simulation results show that CPBSC effectively increases the resource utilization and improves the whole cache performance.
