Abstract

The invention discloses a hardware monitoring and micro-packet protocol-based key data restoration method in a triple modular redundancy fault-tolerant computer system. The method is characterized by comprising the following steps of: dividing to-be-restored key data into hardware data blocks with equal size and dividing each hardware data block into monitoring packets with the same size; meanwhile, setting a monitor on hardware aiming at each hardware data block, wherein the number of the monitoring packets which can be monitored by the monitor is equal to that of the monitoring packets obtained by dividing each hardware data block; forming a basis for retransmitting a data region of the hardware data block once the condition that the monitoring packet is updated or amended is discovered; and retransmitting data with packet as a unit so as to reduce retransmitted data quantity.

Description

technical field

[0001] The invention relates to a key data recovery method in a triple-mode redundant fault-tolerant computer system, in particular to a key data recovery method in a triple-mode redundant fault-tolerant computer system based on hardware monitoring and a micropacket protocol. Background technique

[0002] Triple-mode redundant (TMR) fault-tolerant computers are usually used in environments that require high reliability. If one of the machines fails seriously, the system will be downgraded to a dual-level operation mode, and the faulty machine will be restored during the dual-machine operation, and During the recovery process, the normal operation of the system is not interrupted, so that the system can be restored from the dual-computer operation mode to the three-mode operation state, thereby improving the reliability and continuity of the three-mode redundant fault-tolerant computer. . For a repairable TMR fault-tolerant system, recovery is an important pa...
