基于P2P混合模式的网络即时通讯与资源共享软件研究与实现

P2P hybrid model can effectively balance the network server and client load, enhance the overall performance of the software system. This paper firstly analyzes the implementation technologies of TCP/IP protocol and socket in the Windows, and discusses the P2P hybrid model. and then, The network instant communication and resource sharing software was implemented based on hybrid P2P model with VS2010 platform, which realizes the user management, communication management, resource upload management and resource download management etc.. The software has friendly interface and stable performance, which not only can significantly improves this kind software performance, but alos can provide reliable technical support to instant communication and resource sharing in small and medium-sized enterprises and groups internal.
