基于Linux和高速网络环境的网络监控系统设计

目前,基于Linux的网络监控系统不多,大多数传统的网络监控系统在高速网络环境下经常出现丢包现象。为此,结合分层软件设计和协议分析技术,设计了一个基于Linux和高速网络环境的网络监控系统。在系统的关键部位引入缓冲队列集,并利用同步信号量机制来同步数据包截获和分析在速度上的差异,同时使用延迟写方式来降低磁盘的读写开销,进一步优化了系统的性能。该网络监控系统有效地解决了高速网络环境下的数据包截获和分析的问题,可以较好地完成目前高速网络环境下的网络监控任务。

Design of Network Monitoring System Based on Linux and High Speed Network Environment

At present, there are few network monitoring systems based on Linux. Most of the traditional network monitoring systems always lose packets under high speed network environment. So, through combining the multi - tier application software design technology with protocol analysis technology, a network monitoring system based on Linux and high speed network environment was designed. Buffer queue set was used in the system's key positions. Synchronized semaphore mechanism was used to synchronize the difference between data packets capture speed and analysis speed. Delay writing method was adopted to reduce disk read - write spending. All these measures optimize the system performance. This network monitoring system can effectively solve the problem of data packets capture and analysis under high speed network environment, and it can preferably complete the network monitoring task under high speed network environment at present.
