文档介绍：摘要
随着因特网技术的发展,网络通信问题日益成为人们关注的焦点,IP包流量分析程序便是一种分析网络状况的有效方法,它从数据包流量分析角度出发,通过实时地收集和监视网络数据包信息,来检查网络数据传输的状态,从而监控网络环境。当前,网络在人们生活中发挥着越来越大的作用,人们也对网络有了越来越高的需求,要适应时代的需要,提供完善便利的网络服务,进行IP包流量分析的课题研究很有必要。分析IP网络流量,开展IP网络流量的监测活动,对IP网络的发展都具有极其重要的意义。
本设计是针对于IP包流量分析的,对所经过的IP数据包进行分析可以得到一系列对应的属性值。通过对这些IP数据包属性值进行对应的解析可以得到该网络具体的通信情况。IP包流量分析程序使用RAW SOCKET设置网卡混杂模式以此来接受经过的数据包,并且运用链表结构来存储符合条件的数据包,实现了分析IP数据包来源、类型、数量及长度的功能。IP包流量分析程序的功能实现,有助于我们对网络的数据传递以及数据包类型进行掌握和分析,有助于对流量的多少进行判定,便于对发生或即将发生的网络问题进行提前防范。

ABSTRACT
With the technology, munication is increasingly ing the focus of attention, IP packet traffic analysis program is one effective method work conditions, it is the angle from the data packet traffic analysis, real-work data collection and monitoring Package information, to check the status work data transmission to monitor work environment. At present, work plays in people's lives increasingly important role, it also has increasingly high demand for work to meet the needs of the times, providing convenient services, IP packet flow analysis for research Necessary. Analysis of work traffic, work traffic to carry out monitoring activities, the development of the work are of great importance.
This design is aimed at the IP packet flow analysis, on which the IP data packets through the corresponding analysis can be a series of corresponding attribute values. IP data packets through the corresponding attribute values resolve to get the specific circumstances of work. IP packet traffic analysis program that uses RAW SOCKET set promiscuous mode in order to accept the card after the data packets, and the use of linked list structures to store eligible packets of IP data packets to achieve the source, type, number and length features. IP packet traffic analysis program implementation, help us work data transmission and data packet type for control and analysis, help to determine the amount of traffic, facilitate, or is about to advance to work problems.
