摘 要

近年來，計算機技術尤其是互聯(lián)網(wǎng)的普及給我們的生活帶來了豐富多彩的內(nèi)容。我們在驚嘆網(wǎng)絡的快捷的同時，也或多或少因為資源的相對匱乏而苦惱。而一種稱為P2P的技術在信息共享中被廣泛應用。該技術提供了一種點對點的信息共享方式，受到了互聯(lián)網(wǎng)用戶的極大歡迎。我們?nèi)粘Ｉ钪械牡牡湫蚉2P技術運用有BT、eMule、迅雷、網(wǎng)絡電視等等。P2P技術在信息共享應用中的潛力是有目共睹的。
目前我校校園網(wǎng)內(nèi)用戶共享資源的方式主要有四種：校園網(wǎng)FTP、校內(nèi)BT站、QQ群以及移動硬盤等。
本文對這些途徑存在的不足進行了分析，并針對湖南大學校園網(wǎng)絡環(huán)境推出了一款新的資源共享平臺。這個平臺能有效規(guī)避校園網(wǎng)出口小的缺點，利用充足的內(nèi)部帶寬及分散的資源服務器形式，實現(xiàn)海量資源的高速共享。文中從設計到實現(xiàn)對該平臺做了詳細闡述。
對如何將一個軟件產(chǎn)品應用到具體環(huán)境并使之與校園生活有機結(jié)合起來這一問題，本文也總結(jié)了一些經(jīng)驗。最后的目的，是為湖南大學校園網(wǎng)用戶建立一個自由、快速、方便的資源共享平臺，以促使大家積極加入到校園網(wǎng)絡文化建設中來。

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.
