| 摘 要： | 网络流量1测量系统提供了一种测量和理解网络流量特性的工具。该文首先介绍了网络流量测量系统框架和当前流行的抓包构件BPF的原理,深入分析了造成基于BPF构件的被动网络测量系统可能的丢包因素,并给出了相应的解决办法;设计和实现了一种基于多采集器的网络流量测量系统;测试表明,与基于单采集器的被动网络流量测量系统相比,该系统明显减少了采集器端的丢包率,提高了系统测量的准确性。

| Abstract: | The traffic flow measurement system provides a tool to measure and understand the network traffic flow characteristics.ln this paper,the traffic flow measurement architecture and the principles of the popular packet capture component BPF are introduced firstly,then the analysis of possible packet loss factors in passive network measurement system based on BPF component and the corresponding solutions are given;at the end,a multi-meter based traffic flow measurement system is implemented.The test indicates that compared with single-meter based traffic flow measurement system,the system reduces the packet loss ratio obviously and enhances the measurement veracity. |
