本文首先分章介绍 P2P 技术、P2P对等点发现技术、网络技术、面向对象的网络fr a mework 技术；然后实现一个P2P对等点发现模型，以及利用设计模式思想实现对 WINSOK 的面向对象的封装，实现TCP，UDP，及同步时间分离模型(Reactor模型)和主动器模型(Proactor模型)，并实现相应的测试程序。-At first,This text divides Chapters to introduce P2P technology, P2P peer discovery technology, network technology and object oriented network fr a mework technology　Then, realize a P2P peer discovery model, As well as realize using design pattern thought for the object oriented case of WINSOK, realize TCP, UDP, and synchronous time split model(Reactor model) and active ware model(Proactor model), realize corresponding test programs .
