A Stochastic Push Scheme of Streaming Media Partial Content based on P2P

Abstract

In streaming media CDN, pushing copies of the new content to caching proxies ahead of time while allowing others to be pulled from the origin server is an effective way to reduce the client startup time and save network resource. In order to cope with the shortcomings of the existing streaming media CDN and accomplish large-scale deployment streaming media on the Internet, in this paper, first, we put forward a framework of streaming media CDN based on P2P. Second, streaming media content delivery strategies have been studied, according to the access feature of different part of streaming media file, we present a stochastic push scheme based on the access characteristics of streaming media and put forward a stochastic algorithm of destination selection using the history access information of the origin server recorded. The experiments indicate that the scheme and the algorithm are effective
