| Abstract: | Based on mining the network video and audio date in multilayer and statistics analyzing user action,a prediction model of popularity prediction is constituted.According to this model,a intelligent proxy cache replacement strategy is put forward.The simulation experiments show that this strategy can improve the cache hit rate and reduce the delay time of client. |
