摘要:随着计算机网络技术的快速发展，电脑终端的网络安全日益受到关注。自从网络能够为我们提供音频甚至是视频功能服务后，使用宽带上网的网民也急剧增加。大多数用户上网的原因就是能够更快地下载自己所需的音、视频文件，因此互联网上那些数量有限的音、视频服务器通常都要在超负荷的状态下长时间工作，甚至导致一些从事媒体服务的服务器在当大量使用者连续不断地访问时发生瘫痪的问题。在这种背景下，由于工作模式的便利性，P2P数据网络得到越来越多的网民甚至是网络开发者的青睐，因为P2P的工作模式解决了集中式的媒体服务器可能会出现的瓶颈性的问题。目前各种各样的互联网软件应用日益激增，同时也产生了非常多的网络信息垃圾甚至是网络病毒，因此加强对互联网的管理和控制才显得更加重要。本设计目的是在windows平台下实现的一个能够鉴别互联网中使用P2P技术传输的数据包内的交互指令的软件程序，该软件运用互联网络信息捕获手段，通信跟踪技术，信息筛选手段来获取网络传输过程中的那些原始数据，再进行步步分析，读取有关协议里面用来进行通信的数据信息和传输控制信息，并对所提取出来的协议信息进行报告和显示，该软件能够帮助我们查找和过滤掉那些有害于我们正常的网络生活的网络数据。通过实时数据捕获与网络信息监控，实现对信息进行过滤和跟踪，这就是本课题研究的目的和意义。

Abstract:As the computer internet develop to now, the security issues of network security are more serious. Since the network can provide us with audio and even video service, the user of internet are also increased dramatically. The reason that why most users get online is to be able to download those audio or video files faster, a limited number of audio on the internet, and their servers usually work long hours in an overloaded state, and even lead to some servers is paralyzed when a large number of users are constantly visiting. In this context, p2p is used by the majority of internet users and network developers in their work, the p2p solve the bottlenecks of centralized media server. At present, a variety of internet software applications are increasing, but also with a lot of network information garbage and even network viruses, so strengthen the management and control of the Internet is even more important. The purpose of this design is to achieve a software that work in the windows platform to identify the interactive instruction using p2p technology to transmit data packets in the Internet. The software uses the Internet information capture means, communication tracking technology, information filtering means to obtain the original data in the process of network transmission, and then report and display the protocol information extracted, the software can help us find and filter out the network data that is harmful to our normal network life. Through real-time data capture and network information monitoring, we can achieve the information filtering and tracking.This is the purpose of this research and significance.

Key words:P2P; WireShark; P2P communication; Network packet
