摘    要

 近年来，计算机技术尤其是互联网的普及给我们的生活带来了丰富多彩的内容。我们在惊叹网络的快捷的同时，也或多或少因为资源的相对匮乏而苦恼。而一种称为P2P的技术在信息共享中被广泛应用。该技术提供了一种点对点的信息共享方式，受到了互联网用户的极大欢迎。我们日常生活中的的典型P2P技术运用有BT、eMule、迅雷、网络电视等等。P2P技术在信息共享应用中的潜力是有目共睹的。
 目前我校校园网内用户共享资源的方式主要有四种：校园网FTP、校内BT站、QQ群以及移动硬盘等。
 本文对这些途径存在的不足进行了分析，并针对湖南大学校园网络环境推出了一款新的资源共享平台。这个平台能有效规避校园网出口小的缺点，利用充足的内部带宽及分散的资源服务器形式，实现海量资源的高速共享。文中从设计到实现对该平台做了详细阐述。
 对如何将一个软件产品应用到具体环境并使之与校园生活有机结合起来这一问题，本文也总结了一些经验。最后的目的，是为湖南大学校园网用户建立一个自由、快速、方便的资源共享平台，以促使大家积极加入到校园网络文化建设中来。

Research and realization about
the P2P Resource Sharing Platform over LAN
Abstract
 In the past few years, the spread of computer technology, especially the Internet, has brought lots of advantages to our everyday life. When admiring the convenience of the network, we may comparatively feel the short of resource feed. There is a technique named P2P which has been widely used in info-sharing.P2P provided an "point to point" mode of work to share information and this ,has became very popular. Some typical applications of P2P are BT, eMule, Thunder, internetTV and so on. In a word, as people see,P2P has great potential.
 Currently, there are mainly four methods for our campus network users to share resource: Campus FTP, Campus BT, QQ Group and removable storage medium.
 This paper analyzes the weakness of the four methods above, and develops a new Resource Sharing Platform against the network environment of Hunan University. This platform can evade the shortage of the outgoing band width of our campus network, and use the sufficient internal bandwidth and those distributed resource servers to make the high speed sharing of mass resource possible. And this paper states the platform in detail from designing to realizing.
 This paper also concluded some experience on how to apply a software product to a real environment and blend it in our campus life well. And the final goal is to build a free, fast and convenient Resource Sharing Platform, and make everyone join in the construction of the campus network culture.
