Abstract

Abstract: P2P applications are widely used and make tremendous traffic in today’s network. With the increasing number of IPTV users, it is reasonable to foresee that P2P live media streaming media will account for a considerable proportion in future backbone traffic. Few works focus on the P2P live media streaming cache in the view of ISP and directly compare its performance with the P2P file delivery. The paper studies the various cache replacement algorithms and caching differences between P2P live media streaming and P2P file delivery, then proposes a novel “time sensitive” cache algorithm for P2P live media streaming called Time over Weight (TOW) and confirms its better performance than popular algorithm such as FIFO, LRU, LSB and LFU.

Keywords: cache replacement algorithm P2P live streaming，hit rate
