当今社会科技日新月异.信息技术的崛起正在悄然改变着人们的生活,学习和工作；然而在人们对网络的应用日渐普遍的时候,各种安全隐患渐渐地浮现在世人眼前；为了有效的避免这些不明因素带来的安全隐患,网络监控应运而生.网络监控是一门新兴技术,它的核心在于能够有效的针对网络中传输的数据包进行检测、捕获、分析,然后根据分析的信息人们可以有意的避免各种网络入侵；所以,该工具的产生使得网络安全更加安全可靠,且具有很高的应用意义.
本文基于网络数据包捕获为基础,通过协议分析数据包以达到检测数据包是否对网络具有攻击性这一目的.本文介绍了几种系统实现算法,重点指出网络流量自相似性原理的应用；通过网络攻击时变化后的自相似性值与前提设置的Hurst值进行比较,如果变化以后的相似性值超过了Hurst值,就认为发生了网络攻击.本系统设计简单,操作便利；通过系统子模块间相互调用,进一步实现网络监控这一目的,具有较高的现实意义.

In today's society science and technology with each passing day. The rise of information technology is quietly changing people's life, study and work; However when people increasingly widespread application of Internet, all kinds of potential safety problems gradually emerge in front of the world; In order to effectively avoid these uncertain factors bring safe hidden trouble, network monitoring arises at the historic moment. Network monitoring is an emerging technology, its core is to effectively detect in view of the network transmission of data packets, capture, analysis, and then according to the analysis of information people can to avoid all sorts of network intrusion; So, the generation of the tool makes network security is more safe and reliable, and has the very high application significance. Based on network packet capture, packet through the analysis of the protocol to detect whether packets on the network aggressive this purpose. Several system are introduced in this algorithm, the key points out that the network traffic self-similarity principle of application; Attack after change the self-similarity of value through the network and the premise set Hurst value comparison, if change after the similarity value exceeded the Hurst, think network attack happened. This system design is simple, operation is convenient; Through the system call each other between sub-modules, further realize the network monitoring this goal, has the high practical significance.
