Abstract:
The domestic meteorological communication system CTS (China Telecommunication System) 10 is an important part of CIMISS (China Integrated Meteorological Information Service System), while the data transmission performance of CTS10 is also one of the key indicators for all provincial meteorological departments in weather information services. However, at present, the provincial CTS 1.0 lacks effective backup means, which leads to dangers in its running continuity. In this paper, considering the costeffectiveness and complexity of operation and maintenance, the author proposes a provincial CTS 1.0 backup plan of singlemachine version, and analyzes its system architecture, data flow, basic platform selection and other key contents. In this plan, the process of service switching is elaborately designed to ensure the consistency of service configuration and the uninterrupted monitoring of data flow, and to ensure the service continuity in the process of singlemachine version CTS switching. At the same time, the SSD solidstate hard disk is used to replace the disk array in the infrastructure, which achieves the higher I/O performance of the system and significantly improves the carrying capacity of the standalone version. Through the pressure test and I/O performance analysis of some provincial services, it shows that the plan can provide the reliable support for provincial CTS 1.0 service backup.
