and C/S (Client/Server, Client/Server) mode, multi protocol conversion munication protocol implemented. Then, the paper of the instant messaging system server and client modules of the main ponents of a detailed analysis, discusses the detailed design of each module and implementation, respectively, described the main function of each module, and gives the module flow chart. Finally, the paper of the instant messaging system designed for serverside performance test, and test data were analyzed. Experimental data show that the system has easy to implement, reliable, scalable, and high transmission efficiency, achieved its design goals.
