Design of Dual Redundancy Communication for VoIP Control and Command System
Firstly,aiming at the high reliability requirements of voice communication and switching system in military and civil aviation airports in China,the feasibility of dual redundant communication scheme for the main and backup switching services is analyzed based on a centralized system architec-ture.Then,from the perspective of dual system collaborative operation,a synchronization method and design process for the switching decision of the main and backup systems and node distribution are pro-posed.Finally,through synchronization testing of dual redundant communication,the strong real-time and high reliability performance of the method is verified.Compared with the traditional dual standby redundant communication mode,the method has more reasonable design and more convenient and flexible system deployment.It can serve as a guide for highly reliable communication applications in fu-ture military and civil aviation control and command.
