摘　　要：网络实时通信软件是当前一个热门的互联网应用工具软件,其主要特点是无论何时何地连入因特网,通过用户账户与密码就可以方便地与在线好友实时通信。本文尝试采用C/S与P2P混合结构,一方面与目前因特网主要的技术模式(C/S)保持一致,另一方面通过引入P2P模式弱化服务器的作用,实现客户之间点对点的传送,而不必经过服务器,提高客户之间的通信效率。在此网络结构基础上,运用Web服务技术实现服务器端的主要服务,以便更加有效地减轻服务器的负荷,有利于以后软件的升级和维护,增加了软件的可扩充性。Nowadays, network instant messengers are a kind of popular software for Internet application. Their main characteristic is that, whenever and wherever users have connected to the Internet, they can perform real-time communication with their on-line friends through input IDs and passwords. This paper adopts mixed structure of C/S and P2P, thus on the one hand it can be consistent with main technology mode （C/S） for current Internet, while on the other hand through importing the P2P mode to avoid the function of server. It can implement point-to-point transmission between clients without using the server to improve the communication efficiency. Based on this network structure, this paper proposes the application of Web services technologies to implement the main services on the server edge, and in this way, to reduce the load of server more effectively, making for future upgrade and maintenance of software and enhancing their extensibilitv.
