Layered Design and Collaborative Development of Network System and Its Application in Real- time Information Cluster

In order to achieve the integrated optimization in developing the big network system, this paper presented the concepts and principles of layered design method and collaborative development using of different tools firstly. Then we gave a recommended layered architecture for the distributed computing network system and also analyzed its pros and cons. At last, we extended the distributed computing network system to an information server cluster based on the task scheduling of dynamic and self-adaptive algorithm. The application of real-time information system designed by layered architecture shows that the method proposed in this paper is practical and efficient.
