Abstract:A new generation of national meteorological communication system is established in China Meteorological Administration. For the high demand of data transmission time, the huge amount of information data, complex and irregular transmission, incomprehensive monitoring and other problems, the provincial and national level unified management platform is established with the data transmission and processing and system monitoring function based on the Symantec VCS (VERITAS Cluster Server) technology. The meteorological communication system to achieve high availability, easy scalability, and the standardization of business processes, improves data processing capacity and transmition capacity. In the business operational test, all observation data can be transmitted to the National Meteorological Information Center within the prescribed time, and the system can still function properly when an exception occurs on any node. The test results show that: the system is stable, monitoring is comprehensive, so as to meet the design objective. This paper describes the construction of the system, the background and purpose, overall system architecture, implementation details, and other key technologies.
