The Design And Implement Of Communication System In Cluster

The communication station includes many kinds of traditional or modern communication ways, such as short wave, wire (DDN, dial in service) and satellite communication. The system must be in time, reliable, safe, correct, highly effective, intelligentized and extensible. At the same time, to adapt to the development of the communication networks the communication system must be an Intranet system that is isolated to Internet by using TCP/IP protocols. Considering the high availability and safety of the system, we construct the system to complete stabile and available file transfer and ensure the system running correctly or continuously when malfunction happened. The basic technology of file store and transfer was discussed in this paper, and the hotspot of computer field----HA Cluster System technology was also presented. In this paper, we discuss some basic points of design HA Cluster system, such as Failure Monitor~ Heart Beat and Agent, which are widely used in most Cluster system. Especially, we analysis the basic mode of the communication system and put forward the project of I-IA Cluster system. We design and develop a communication subsystem to complete file receive and send in one link without people by using object oriented technology. The communication subsystem refers to develop some special protocols used to complete sending and receiving files correctly and secretly. Starting and stopping of the multithread is controlled. We also design a stack to manage the interlock and share among multithread. We discuss the way of accessing Sybase Database and managing the messages.
