Cache mechanism in P2P streaming media system

Providing streaming media service over the Internet is challenging. Since this requires high communication bandwidth for delivery. How to avoid the bottleneck of the streaming media service with the use of P2P system has become a hotspot. In this paper, we review the existing caching management and propose a novel cache allocation fit for P2P streaming media system. Our approach allows the system to retain many copies of popular videos to avoid creating hot spots and at the same time, prevent unpopular videos from being quickly evicted from the system.
