摘　　要：国内气象通信系统CTS1.0是CIMISS业务的重要组成部分,其资料传输情况也是各省气象信息业务考核的重要指标之一。但目前省级CTS1.0缺少有效的备份手段,导致其在运行连续性方面存在隐患。在本文中,作者从性价比、运维复杂度等方面综合考虑,提出了一套单机版的省级CTS1.0备份方案,并对其系统架构、数据流程、基础平台选型等关键内容进行了分析。该方案对业务切换过程进行了精细化设计,确保业务配置一致性及监控数据流转的不间断,保证了单机版CTS切换过程中的业务连续性。同时在基础架构方面,采用SSD固态硬盘替代磁盘阵列,获得了较高的系统I/O性能,使单机版承载能力显著提升。通过在部分省局进行的压力测试以及对系统I/O性能的分析,表明该方案能够为省级CTS1.0业务备份提供可靠的支撑。The domestic meteorological communication system CTS(China Telecommunication System)1.0 is an important part of CIMISS(China Integrated Meteorological Information Service System),while the data transmission performance of CTS1.0 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 cost-effectiveness and complexity of operation and maintenance,the author proposes a provincial CTS 1.0 backup plan of single-machine 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 single-machine version CTS switching.At the same tim e,the SSD solid-state 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 stand-alone 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.
