Using cluster technology for establishing meteorological communication system based on shared memory

National meteorological communication system is the main project in CMA. For improving system credibility,the system uses the load balance technology to build cluster system. The communication servers make use of cluster technology to ensure that all of the servers in the cluster system can share the storage. In this article, cluster and cluster file system are introduced. Future more, the architecture of National meteorological communication system is analyzed based on cluster, and at last we present the scheme of establishing meteorological communication system based on shared memory.
