基于P2P的流媒体客户端缓存管理机制的研究
Research on the Client Buffer Cache Based on Peer to Peer for Video on Demand System
摘要
Abstract
According to the problem of the quality of service of streaming Video-On-Demand been affected by the inefficient utilize of client buffer cache in Peer to Peer(P2P) Video-On-Demand system, this paper presents P2PVOD, a streaming media Video-C)n-Demand model based on hybrid P2P, the client buffer cache been divided into three partitions in this model and discusses in detail the buffer control strategy of client buffer cache, it considers the proportionality of the data blocks distribution and the hit rate of peer VCR operation comprehensively to remit the server load and optimize the distribution of data blocks between the peers, and verifies the advantages of the model in start delay and server load through contrast experiments.关键词
