摘  要
   經過幾十年的發展，Internet上的資源逐漸豐富起來，資源的流向趨于集中化，網絡應用多以集中化方式提供服務， P2P技術不同于基于Server的集中化應用技術，它是基于P2P拓撲結構發展起來的一項新型網絡通訊技術,P2P就是一種用于不同PC用戶之間，不經過中繼設備直接交換數據或服務的技術，它允許Internet用戶直接使用對方的文件。每個人可以直接連接到其他用戶的計算機，并進行文件的交換，而不需要連接到服務器上再進行瀏覽與下載。因為消除了中間環節，P2P技術使得網絡上的溝通變得更容易、更直接。本題目是設計實現“在局域網中實現兩臺機子之間的通信,包括消息和語音的實時發送和接收,文件的傳輸等”，我在老師的指導下，通過閱讀相關的參考資料，從基本線程開始然后是編寫調度線程，設計界面，增加要求的功能。經過反復的編程與調試，程序基本上實現了Peer-to-Peer的模式，實現了基本的功能。

Abstract
  With the development of the Internet in past 40 years, the resources were richer and richer, while the flow of the resources went to centralize. Most of the services were supplied by the implication of the network in a central way. P2P technology is different from the central implication technology which was on the base of server, it was a new network communication technology which was developed on the base of P2P topology. P2P is a kind of technology used between different pc users which changes data or services directly rather than connecting to the server. It allows the users in the Internet to use the file of others directly. Everyone on line can connect to each other and change their files. Because of the lack of the middle medium, p2p technology made the communication on line more easily and more directly. My project is "the communication of two PCs in LAN, including the sent and receive of the message and translation of the file". With the guidance of my teacher, I have completed this project basically. I design the interface firstly; and then programmed the manage thread; finally, after the debug, the project was completed in p2p model, and have met the requirement of the functions.
