一个改进的BitTorrent类型流媒体系统模型

Enhanced BiTorrent-like media streaming system model

本文首先介绍了BitTorrent类型流媒体系统的概念,然后在分析BitTorrent类型流媒体系统和具有代表性的多源流媒体系统模型-基于CollectCast协议的PROMISE的基础上,针对BitTorrent类型流媒体系统缺乏发送节点智能选择算法提出了一种采用CollectCast协议改进的BitTorrent流媒体系统模型,仿真实验证明该模型的性能优于普通的BitTorrent类型流媒体系统。

This paper first introduces the concept of BitTorrent-like media streaming system,then proposes a BiTorrent-like media streaming system model improved by CollectCast protocol to redeem the lack of wise sender selection algorithm based on analyzing BitTorrent-like media streaming system and the most typical multi-source media streaming system,PROMISE which is based on Collectcast protocol.simulation results show that the model has better performance than ordinary BitTorrent-like media streaming system.
