摘　　要：当前计算机网络的规模不断扩大，复杂性不断增加，网络的负荷也逐渐增加。用户对网络性能要求的提高，以及网络本身的缺陷等都影响到网络的性能。因此网络的管理和安全问题日益成为网络技术研究的一个重要方面。为了提高信息安全性，特开发局域网数据包截取与分析系统，系统基于C＋＋技术和Access数据库的配合，在研究网络数据包捕获、TCP/IP原理的基础上，综合采用了Raw-Socket、多线程的创建和挂起等编程技术，实现数据包捕获、拆解和分析，有效数据的存储与查询等功能，为网络管理员了解网络运行状态提供了参考。The scale expands unceasingly, the complexity of the current computer network increases, network load also gradually increased. Users to improve the network performance requirements, as well as the defects of network itself and so on all affect the performance of the network. Therefore, network management and security problem has increasingly become an important aspect of the network technology research. In order to improve the safety of information, developing the local area network packet cap-ture and analysis system, which based on c＋＋technology and Access database, in a research network packet capture, based on the principle of TCP/IP, and integrated with the Raw Socket, multi-threaded programming technology such as creating and hung, implemented packet capture, dismantling, and analysis of efficient data storage and query functions, provides reference for net-work administrators to understand the running state of the network.
