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.
