| Abstract: | In order to promote the quality of service(QoS) of streaming system based on P2P technology,the smallest cache value(SDU) is proposed.First the existing cache replacement algorithm is researched.Based on these,by analyzing the existing cache replacement algorithm we can obtain that the efficiency of the existing cache replacement is not high in the P2P network.Then the P2P network and streaming media system are analyzed.And then SDU algorithm is proposed.SDU considers copy's supply and demand, data's necess... |
