P2P流量监控系统的设计与实现

Design and Implementation of P2P Network Traffic Monitoring System

当前P2P技术迅速发展,网络占有率越来越高,这使得其他重要的网络数据流量减小,网络服务质量下降。对P2P流量进行监控,已经成为网络管理的重要环节。设计了一种P2P流量监控系统,系统对数据流的检测采用深层数据包检测和深度流检测相结合的方式。阐述了系统实现所需的主要技术,给出了实现所需的关键算法。

Peer-to-Peer technology is increasingly developed, consuming most network traffic resources. Other important data streams have less bandwidth because of kinds of P2P application, which results in the declination of Web Service quality. Monitoring P2P traffic has become a chief link of network management. A P2P traffic monitoring system is designed, which uses deep packet inspection combined with deep flow inspection to inspect data stream of the network. The chain technology used during the implementation of this system is discussed about, and the main algorithms are proposed.
