Research on reliability design of network nodes in operational command and control system

In view of the problem of dual computer hot standby for key nodes, a new reliability design is put forward to enhance their usability in operational command and control system based on information exchange device. The original data exchange module can be replaced perfectly. The result does not affect the primitive design and function, but further support dynamically modifying network configuration, outputting priority of the device. This method can be applied widely in dual computer hot standby with higher performance demand.
