基于NetFlow V9协议的网络信息采集研究与实现

Research and Implementation of Network Information Collection Based on NetFlow V9 Protocol

NetFlow是目前主要的网络信息采集协议之一,V9是它的最新版本,它可在最大限度减小对路由器/交换机性能影响的前提下,提供详细的数据流统计信息。该文结合网络性能管理软件项目(NPMS)的开发,讨论了基于NetFlow(V9)协议的网络信息采集的研究与实现,即对NetFlow(V9)数据流的解析与保存。

NetFlow is one of the most important network information collection protocol , and its latest version is V9 . NetFlow can provide detailed statistic information of network flow on the promise of furthest reducing the influences of the performance of routers and switches. This paper discusses the research and implementation of network information collection based on the NetFlow V9 protocol according to the development of NPMS （Network Performance Manage System）, that is , how to parse and store the NerFlow V9 flow.
