基于嵌入式的P2P流量监控系统的设计及实现

摘要

The extensive use of P2P (Peer-to-Peer) network technology has a serious impact on traditional business of the existing network. A P2P traffic monitoring system based on embedded technology is designed, which uses deep packet inspection (DPI) technology for P2P traffic identification and uses bypass interference for P2P traffic control. Through establishing different identification and control strategies, the system can extend to other P2P traffic monitoring. The experimental result shows that the designed system has a good scalability and high detection.%P2P业务消耗大量的网络带宽资源,使互联网传统业务的服务质量下降,针对这个问题,设计了一种基于嵌入式技术的P2P流量监控系统.该嵌入式系统采用深层数据包检测(deep packet inspection,DPI)的流量检测技术,使用旁路干扰的控制方式,并具有扩展到对新的P2P业务流量监控的功能.测试结果表明该嵌入式系统检测和控制P2P业务流量的效果良好,扩展性较强.
