摘要: 提出了一种基于Netflow的网络流量监测系统,介绍了系统中各组件的功能,并对其中的核心部分——Netflow处理模块——进行了分析;该模块的设计采用基于事件驱动的异步网络框架Twsited,与传统的基于进程或多线程的设计相比,该设计节省了系统资源,避免了多线程的复杂性并且在网络流量很高的情况下具有很好的吞吐性能。

关键词: 流量监测, Netflow, 异步服务

Abstract: A network traffic monitor system based on Netflow is presented, and the components of the system are introduced. An analysis is given on the Netflow-processing module, which is the core part of the system. The design of the Netflow-processing module is based on Twsited, which is an asynchronous event-driven networking framework. Compared to the traditional designs based on procedure or multi-thread, such design can save system resource, avoid complexity caused by multi-thread and gain good throughput under high network traffic.

Key words: Traffic monitor, Netflow, Asynchronous service
