Abstract
This research conducts an in-depth analysis of the dual-machine synchronization mechanism of the DMHS-V automatic message switching system.The system employs a dual-machine hot standby architecture,multi-level hardware redundancy,and a mixed AA/AB working mode.By combining full synchronization strategies during the startup phase and real-time incremental synchronization strategies during the operation phase,it effectively ensures the reliability of key data transmission,such as civil aviation messages,and achieves rapid failover.The study delves into the basic architecture,synchronization process,and exception handling strategies of the system.It also points out bottlenecks in network dependency,synchronization time window constraints,and the complexity of mixed-mode coordination,and proposes targeted optimization suggestions.This research provides a theoretical basis and development direction for introducing intelligent disaster recovery,quantum communication,and a cloud-native architecture into the next generation of automatic message switching systems.关键词
