Design And Implementation Of Enterprise Instant Messaging System

Instant messaging is currently the most popular way to communicate on the Internet. Because of the variety of instant messaging software have been coming out, the service providers are supporting more plentiful communication services function. As the development of the Internet, instant messaging will be used widely and instant messaging software will be flourishing.This paper first described the development and the current status of the instant messaging, and preliminary discussed the technologies of the instant messaging such as communication protocol, service mode and friend-making mode. The existing technology are compared and analyzed, and some possible improving methods are presented, a instant messaging systems called InstantMessage is designed at last. The InstantMessage instant messaging system uses TCP protocol as the transfer protocol.It combines C/S and P2P as the architecture of communicate model. UML and object-oriented analysis are used in the process of system design and modeling. The system used Rose as the modeling tool, and VS2008as developing tool. It made some new features of.Net applied in this system, and reconstruction development method to optimize the design of system during the developing process.
