基于ZeroMQ的民航空管数据库同步软件设计和应用

Design and application of civil aviation air traffic control database synchronization software based on ZeroMQ

文章针对广域网架构下的多数据副本的数据一致性问题,提出了基于ZeroMQ及增量数据抽取的同步方案,研制了同步软件UltraSync。在中国民航流量管理系统的研制与应用中,UltraSync能高效地同步中心节点数据分布在全国的二级分系统,有效解决了核心数据的分布式存储问题。

This article is aimed at the data consistency problem of multiple data copies under the WAN architecture,a synchronization scheme based on ZeroMQ and incremental data extraction is proposed,and the synchronization software UltraSync is developed.In the development and implementation of the National Civil Aviation Traffic Management System,UltraSync can efficiently synchronize central data to secondary sub-systems distributed across the country,effectively solving the problem of distributed storage of core data.
