摘要随着互联网的快速发展,网络安全问题渐渐成为人们关注的焦点,像病毒、非法访问、恶意攻击等都会影响网络的正常运行,如今许多网络防御技术都被综合应用于网络安全管理体系中,其中之一能有效分析网络状况的方法就是流量监控系统。它从数据包流量角度来分析,通过实时收集监视网络数据包的信息,来检查是否存在违反安全策略的行为以及网络工作异常的迹象。
本文首先介绍流量监控系统的研究背景和研究的目的以及意义。以研究数据包捕获和TCP/IP原理为基础,采用了面向对象的方法进行需求分析和功能设计。本系统在VC6.0环境下进行开发,综合采用了Winsock、注册表编程等网络编程技术,在需求分析的基础上,对主要功能的实现进行了详细分析与设计,最终通过测试,实现了数据包捕获、流量监控功能,完成了预定要求。30646

Title The Design and Implementation of software for LAN Traffic Monitoring
Abstract
With the rapid development of Internet, network security has become the focus of attention, such as viruses, unauthorized access and malicious attacks will affect the normal operation of the network, now many comprehensive network defense technology has been applied to network security management system, one of which can effectively analysis the condition of network traffic monitoring system. To analyze it from the packet flow Angle, through real-time monitoring network packets of information collection, to check whether there is a violation of security policy and network abnormal signs.
This paper introduces the research background, research purpose and meaning of the traffic monitoring system. By using the way of object-oriented, this design makes a needs analysis and ability designing based on the study of TCP/IP theory and network packet collecting. This system is developed under the environment of VC6.0, comprehensively using the network programming technologies such as Winsock and registry programming, on the basis of demand analysis, the implementation of main functions are analyzed in detail and design, finally passing the test and achieving the function of packet capture, traffic monitoring, then completing the reservation request.
