应用于P2P网络串流的实时监控系统

Real-time Monitoring System with Its Application in Peer-to-peer Streaming

点对点(Peer-to-Peer,P2P)传输架构的新技术能利用用户的网络带宽以及运算能力来分担串流服务系统的负担,对于该网络进行实时监控已经成为近年来的一个研究热点。分析了应用于P2P网络串流的实时监控系统,指出跟踪监控的3类主要方法,即网络级别、被动的应用程序级别和主动应用程序级别的监控。给出了主动应用程序级别的监控模式下监控系统的架构与组成,并通过实验分析了其监控性能。

A new technology, the peer-to-peer （P2P） transmission framework, has been applied in the real-time video/audio streaming system, and it has been a hot researching topic in recent years that designs a real-time monitoring system, and it is applied in peer-to-peer streaming. In this paper, the designation of the real-time monitoring system is analyzed, and the monitoring systems is divided into three types： the network monitoring, the passive application program monitoring and the active application program monitoring systems. An active application program monitoring system is designed and the components of the system is discussed. Some experiments are taken to investigate the performance of the proposed system.
