The powered method of proxy cache for streaming media

The transmission of large capacity and high bit rate for streaming media becomes a challenging problem for the Web application. The proxy cache for streaming media is an efficient method to solve this problem. We propose the algorithm of dynamic cache-multicast based on partial cache method such as the prefix cache, segmented cache etc. The idea of the algorithm is using a dynamic cache to keep partial media object requested by clients in an interval. The advantage is that reference frequency of partial media for the duration is higher than that of full media requested by clients. The cache-multicast method enhances the efficiency of proxy cache for streaming media, mitigates network burden from content server, and saves the traffic resource for the network backbone. Event-driven simulations are introduced to evaluate the effectiveness of this algorithm.
