异步服务的以太网流量监测系统设计

Design of Ethernet traffic monitoring system forasynchronous service

设计一种基于异步服务的以太网流量监测系统设计研究,实时、有效监测以太网流量,并及时提出告警。系统通过NetflowV5将采集的流量监测UDP数据包传输至Netflow处理模块,该模块利用异步服务的Twsited框架完成Netflow Collector和Netflow Analyzer的异步,将异步处理完成的流量数据反馈至Postgresql数据库,通过可与数据库实现信息交互的Web应用提供直观监测结果,应用Ajax设计服务器的告警模块,在流量数据超出设定值时,及时通过警告模块发出告警信息。实验结果表明:该系统可以实时、有效地监测以太网流量变化情况,并在产生异常时及时告警,实现系统的性能与应用优越性,提高开发的简化与资源的节约程度。

An Ethernet traffic monitoring system based on asynchronous service is designed, which can monitor Ethernet traffic in real time and effectively, and give alarm in time. The system transmits the collected UDP packets of traffic monitoring to NetFlow processing module through NetFlow V5. The module completes NetFlow collector and NetFlow by using twsted framework of asynchronous service The asynchronism of analyzer feeds back the data of traffic processed asynchronously to PostgreSQL database. Web applications that can achieve information interaction with the database can provide visual monitoring results. The alarm module of the server is designed by using Ajax. When the traffic data exceeds the set value, the alarm information is sent through the warning module in time. The experimental results show that: the system can monitor the change of Ethernet traffic in real time and effectively, and give an alarm in time when there is abnormal. It realizes the performance and application superiority of the system, and improves the development simplification and resource saving degree.
