Abstract

Abstract

Lack of cache and service time-delay in the media streaming system are considered. PCSPC (Proxy- Caching Scheduler based on P2P Cooperation) is proposed. First according to the principle that more popular data are assigned more cache, corresponding cache is allocated to every media files prefix. And then prefix sequence and proxy sequence are sorted in ascending and descending order respectively by transmission cost, and this method can reduce transmission cost effectively, which is proved by mathematical method. Both cache efficiency and transmission cost are considered in PCSPC. Simulation results show the effectiveness of the strategy.
