As a representative network architecture of future network, CCN has attracted more and more attention from academia and industry. Among many components of CCN, caching policy is the key feature, which directly influences CCN’s performance. In this paper, an interesting topic is explored, i.e. whether the network performance will be promoted if popular and non-popular contents are cached respectively. A cache partition policy based on content popularity is proposed with the theoretical expression derived and the Matlab calculation results provided to verify its performance. The numerical results have shown that, the proposed policy is always superior to the commonly used LCE/LRU policy due to the increased characteristic time.
