摘要: 基于树状拓扑协议及扩展的模型和基于Gossip协议的模型在媒体数据分发方面存在缺陷。针对该问题,提出一种基于区域化的P2P流媒体直播系统模型,采用动态自适应的区域化自治机制,在大规模的流媒体直播网络系统中降低系统管理控制负载的开销,优化系统带宽和时延,提高了流媒体数据资源的利用率。

关键词: P2P流媒体, 树状拓扑协议, Gossip协议, 区域化

Abstract: Considering the shortcomings of the P2P streaming media technology, which based on the model of the tree topology and extensions and Gossip protocol in media data distribution, the model of P2P streaming media live system based on regionalization is proposed, and a dynamic self-governing regionalization mechanism is used. In a large-scale live streaming media network system, the new model reduces the probability of network congestion, and optimizes bandwidth and latency of the system, while improving the streaming data resource utilization.

Key words: P2P streaming media, tree topology protocol, Gossip protocol, regionalization
