摘　　要：结合电信行业实际业务需求,利用数据库代理,设计出了能够提供强一致性、高可用性并支持弹性水平扩展能力的分布式数据库架构.验证结果表明,对于分布式数据库采用数据库代理可满足高可用性与弹性水平扩展的设计要求,实际部署中,双Master部署模式性能体现较佳,读写分离的部署模式、读写操作部署在一台设备性能下降明显,说明数据库代理可以实现高可用性的分布式数据库架构,各类部署架构中影响性能的是磁盘I/O.With the actual business requirements in the telecommunications industry,using database agents,we designed to provide a strong consistency,high availability and scalability to support the level of flexibility of distributed database architecture. Validation results show that for a distributed database using database agents could meet the high level of availability and flexibility of scalable processing requirements. In the actual deployment ,the deployment of dual-master mode performance reflects better,separate reading and writing deployment mode,reading and writing operations in a single deployment equipment performance decreased significantly. This shows that the database agent can achieve high availability distributed database architecture,and the various deployment architectures affect performance disk I/O.
