Analysis of hot-standby scheme of weapon system's center computer
Jianlin Li · Journal of Computer Applications · 2012
The technique of duplicate hot standby is a fault-tolerance scheme combined hardware with software,which is used to make computer system operate in a stable,reliable,efficient and continuous way.As command,control and communications center of a weapon system,the reliability of the center computers can be ensured by a duplicate hot standby scheme.The host computer's working state can be watched by its heartbeat signal to backup computer.The weapon system can work normally by switch between host and backup in case of host fault or no heartbeat signal.Redundance function can be improved by adding network heartbeat after analysis of the scheme,which can be realized by upgrading software not changing hardware.
