Used In E-government Research And Design Of The Instant Messaging System

With the rapid development of computer technology, Instant Message (IM) technology is becoming a most important application after Email and Web. As a new means of communication, IM systems can help people communicate easily. People can transmit files, chat online, hold video meeting on internet. At present, IM system is being used in government, business, and communication fields and so on.First of all, we introduce communication model and communication protocol in some leading IM systems and analyze the insufficiency of these IM systems in egovernment application in this paper. Then we improve some key technology in communication system and design a new IM system which integrates P2P model and server transfer model. It is a compatible mulprotocol and real-name instant system. For improving load ability, Concurrency of communication is managed by network transmission and system deployment.Based on these researches about key technology of IM domain, We propose and implement a IM system for government. The system consists of server module and client module. Server module provide login in, connecting, gateway and database service function. Client module provides a good interview for business communication in government. Client also can integrate many other IM systems.In the end, we summarize our research works and analyze some problems that have not been resolved. We prospect the future research direction. Up to now, the IM system has passed function test and pressure test, and is being used in HangZhou government department widely.
