摘要:

基于P2P的流媒体点播系统,由于实时点播和拖动等VCR操作没有得到有效支持,以及用户不能随意发布节点等原因,没有得到广泛应用。本文提出了一种基于混合P2P的流媒体点播模型TTVOD,讨论了模型的缓存机制,提高了数据冗余度和分发性能,最后通过实验验证了模型的有效性。

Abstract:

Because of the limitation of video sources and deficient VCR support, Video-On-Demand (VOD in short) based on the P2P network is not applied widely. This paper presents TTVOD,a VOD model based on hybrid P2P, mainly discusses the buffer control strategy which improves data delivery efficiency and red undancy, and verifies the validity of the model through experiments.

Key words: hybrid P2P, streaming media;VOD, buffer
