[0026] The method of the present invention is described in detail below with reference to the accompanying drawings.
[0027] The purpose of the present invention is to provide a software fault injection system for reliability evaluation of fault-tolerant systems based on the Ruanji fault injection technology based on the actual requirements of reliability evaluation of fault-tolerant systems, so as to accurately evaluate the reliability of fault-tolerant systems.
[0028] as attached figure 1 As shown, the main part of the evaluation system includes the main control machine and the target machine. The main control machine is responsible for selecting the type of fault injection, sending fault injection instructions, selecting the load generated on the target machine, storing recovery results, and all user interaction operations. The host computer and the target computer are connected through a dedicated heartbeat line, which is used for heartbeat detection on the one hand, a...
