The improvement of cache replacement algorithm in P2P streaming media system

This paper has put forward the new cache replacement algorithm considering the popularity of the program, byte cache efficiency, file use frequency and other factors for P2P streaming media on demand system. The new algorithm can meet the high load requirements of the network. On this basis, it has completed the experiments of simulation in order to verify the new cache replacement algorithm. At the same time, it has compared the results with the traditional cache replacement algorithms and analyzed the advantages and disadvantages of the new algorithm.
