Embodiment Construction

[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...

Abstract

The invention provides a reliability evaluation system design method based on software fault injection. In the method, a computer system is tested and evaluated specific to reliability serving as an important index for evaluating the performance of the computer system, and the fault-tolerance performance of a fault-tolerance system is tested and estimated by means of fault injection which can contribute to accelerating system failure. The invention introduces a design method of a fault injector oriented to reliability evaluation of the fault-tolerance system on the basis of the thought of software fault injection, and the method has the advantages of diverse fault types and triggering ways, realization of injection faults similar to real faults, easiness in operating, small influence on the system and the like, and can be used for effectively evaluating the system reliability.

Description

technical field [0001] The invention belongs to the technical field of operating system reliability evaluation, and relates to a design method of a reliability evaluation system based on software fault injection. Background technique [0002] With the rapid development of computer technology, people have higher and higher requirements for the reliability of computer system software and hardware. How to evaluate system reliability in system design and implementation stage is an important step in developing fault-tolerant computer systems. At present, there is no general method that can be used to analyze the reliability problems of various computer systems. Although there are many design methods to improve the reliability of computer systems, there is a lack of sufficient theoretical proof. Combination methods for computer system reliability design combined with practical applications are even more diverse, and there is no universally recognized standard to follow. [0003...
