%X Considering user access preference in streaming media,the paper proposes a new proxy caching replacement algorithm based on prefix caching and media popularity.The algorithm calculated the predicted popularity using the external and internal popularity of media segment.Then the segment with low popularity is chosen to be replaced.Simulation results demonstrate that,the method can achieve high caching hit rate and reduce request delay under same conditions.
