Abstract

Caching management strategy is a main research aspect for on-demand streaming system on peer-to-peer network. In this paper, we propose a CORPC caching management scheme, which defines a best suitable caching capacity for chunkpsilas replicas. Based on replica capacity, chunk popularity and peer capacity, CORPC scheme adopts heuristic greedy algorithm to implement cache admission control and replacement policy. This scheme can improve QoS of chunks with lower popularity while with little sacrifice of chunks with high popularity. Experiment results show that system QoS is improved obviously with an increase of peerspsila cache capacity.
