网络流量监控及分析工具的设计与实现
摘要
互联网迅速发展的同时,网络安全问题日益成为人们关注的焦点,病毒、恶意攻击、非法访问等都容易影响网络的正常运行,多种网络防御技术被综合应用到网络安全管理体系中,流量监控系统便是其中一种分析网络状况的有效方法,它从数据包流量分析角度,通过实时地收集和监视网络数据包信息,来检查是否有违反安全策略的行为和网络工作异常的迹象。
在研究网络数据包捕获、 TCP/IP原理的基础上,采用面向对象的方法进行了需求分析与功能设计。该系统在VisualC++,综合采用了Socket-Raw、注册表编程和IP助手API等VC编程技术,在系统需求分析的基础上,对主要功能的实现方案和技术细节进行了详细分析与设计,并通过测试,最终实现了数据包捕获、流量监视与统计主要功能,达到了预定要求,为网络管理员了解网络运行状态提供了参考。

The Design and Implementation of Monitoring and Analyzing Tool work Traffic
Abstract
With the rapid development of , network safety has e people’s concern, virus, vigorous attack, illegal visit and so on can easily affect the work performance. Various kinds work defending technology have prehensively applied into the management system work safety. Network traffic system is one of the effective measures to work condition. From the angle of analyzing packet traffic, it can examine the safety violation and the abnormal performance work by timely collecting and monitoring packets information.
By using the way of object-oriented, this design makes a needs analysis and ability designing based on the study work packet collecting and TCP/IP theory. Under the environment of Visual C++, this system adopts VC program technologies of Socket-Raw, Windows register and IpHelper API. On the basis of system analysis, it makes a deliberate analysis and test of plans and details to implement packets collecting, traffic monitoring and statistics. So this meets our needs and makes a reference for managers to get to know work conditions.
Key words: network management; data collection; traffic analysis; Winsock2
