网络流量监测技术

Research on Network Traffic Monitoring Techniques

网络流量监测技术对网络流量行为描述、网络规划、设计和管理提供基本依据,对网络运行的QoS保证和网络安全也产生很大影响。基于路由的网络流量监测技术(RMON、Net Flow、SFlow)以及基于非路由的网络流量监测技术(主动测量和被动测量),分析对比各种监测技术的性能,在此基础上探讨当前两种最新的组合网络流量监测技术:SCNM与WREN。

Network traffic monitoring techniques provide the basis on the description of network traffic, network planning, design and management, also has the very tremendous influence to the network movement＇s QoS guarantee and the network security. This paper discusses router based monitoning technigues （RMON. Netflow, SFlow） and non- based monitoing tcchnigues （pcgsive and active） and comparative analysis of the performance of various monitoring techniques. Finally, discusses the two kind of newest network traffic monitoring techniques： SCNM and WREN.
