| Abstract(in English) | In recent years, peer-to-peer (P2P) systems are becoming more popular as the size of contents becomes larger than before. The number of requests follows the power-law distribution, which means very popular contents are requested frequently. In this unstructured P2P network, cache algorithm like Least Recently Used (LRU) leads to a large amount of duplicated very popular contents in the neighboring peers. This causes a problem, deletion of rarely requested contents. This paper proposes an efficient cache replacement policy using clustering. Proposed method classifies peers and contents by the clustering ID. Peers replace cached contents to the contents bearing the same ID with their clusterig ID. Simulation results show that the policy distributes the different contents among neighboring peers and improves the hit rate. |
