Design and realization of the real-time communication system based on java

摘要

To solve the internal communication and cooperative work problems between the employees in enterprises, a Java-based real-time communication system is developed in this paper, which also improves efficiency and overcomes the poor security disadvantages caused by installation of commercial Internet communication software, such as QQ, MSN, etc. The system performance is greatly improved by Java data object encapsulation, researching the optional transmission model, the application layer optimization algorithm and the version non-destructive extension. Also the filed-based downward compatibility is guaranteed or ensured. What's more, the fault tolerance of the filed-based disappearance has also been largely increased, which provides a good protection mechanism for the hot swap upgrade of business. Besides the security are ensured through installing the server of the real-time communication system inside the enterprise and allowing the system administrators to select the crews.
