摘要
文章主要针对光传输网管系统中网元数量急剧增长导致的网管数据库更新查询效率极低,甚至出现系统崩溃的问题,提出了一种高效的分布式数据库系统架构。该系统采用主从技术、Memcached技术与分布式数据库结合的方式,将数据分散地存储在多台独立的设备上,提高了数据的查询效率。系统容量大、可靠性高、扩展能力强,具有很强的实用性。
With the sharp growth of the elements in optical transmission network management systems,the element management database has low update and query efficiency,or even comes to breakdown.This paper presents an efficient distributed database system architecture,which stores data in multiple independent units by combining the master-slave and mencached technology with the distributed database,thus improving the query efficiency.This system is characteristic of large capacity,high reliability and great scalability,having significant practical application values.
