为了满足数据的一致性、提高性能等需求,同步建设高轨任务中心和低轨任务中心,并互为备份中心,详细阐述了双中心同步管理整体架构及控制流程、跨中心全量同步架构、跨中心增量同步架构、双中心校验和迁移架构,并介绍了数据一致性技术、数据冲突解决技术等关键技术.双中心基于数据同步技术和数据一致性校验技术,可以有力支撑达成中国星网双中心"控制面双活、业务面负载均衡"最终运行状态.
Research on Multi-Active Heterogeneous Data Synchronization Technology in Satellite Internet Scenarios
To meet the requirements of data consistency and performance improvement,we have synchronously constructed both a high-orbit task center and a low-orbit task center,serving as backup centers for each other.We have elaborated on the overall architecture and control flow of dual-center synchronous management,as well as detailed the architectures for cross-center full synchronization,cross-center incremental synchronization and dual-center verification and migration.Key technologies such as data consistency and data conflict resolution are introduced.Based on data synchronization and data consistency verification technologies,the dual-center system can effectively support the final operational state of"active-active control plane and load balancing on the business plane"for the China StarNet dual-center system.
