基于P2P流媒体实时分发模型的异常探测研究

On the Anomaly Detection of the P2P Streaming Media Distribution System

CDN和P2P是现在常用的两种网络加速方法。本文首先简要阐述了CDN和P2P技术,然后针对CDN-P2P混合流媒体分发模型给出了一种探测异常节点的方案。此方案在一定程度上减轻了CDN服务器作为P2P索引节点的监测压力,从而使CDN服务器能更有效地进行流媒体服务。

CDN and P2P are two common approaches for network acceleration. This paper first briefly describes the basic principles of CDN and P2P,and then brings out a method for detecting anomaly node in a CDN-P2P hybrid streaming media distribution system. This method can alleviate the responsibility of the CDN server as a tracker to some extent,and make it provide streaming media services more effectively.
