Embodiment Construction

[0023] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0024] The purpose of the present invention is to try to solve the problems existing in existing hardware fault-tolerant and software fault-tolerant technologies. This paper proposes a fault-tolerant mechanism and strategy based on process redundancy, constructing dual-mode redundancy or multi-mode redundancy for key processes, and adopting process Inter-synchronization and other means ensure that redundant processes run according to the same execution logic, monitor the system and perform corresponding error handling for different errors, so as to improve the reliability and availability of the system.

[0025] The purpose of the present invention is achieved like this, with reference to figure 1 In the fault-tolerant system design method based on process redundancy, all fault-tolerant functional modules are concentrated in the core layer of the operating sy...

Abstract

The invention provides a fault tolerant system design method based on process redundancy. The method includes: using multiple CPUs (central processing units) as redundancy hardware, building redundancy tasks on an independent CPU set and executing the same, comparing redundancy tans executing data to detect faults, using a model descending and restarting mechanism to complete fault restoring, adding a fault tolerant container to a Linux system, allowing applications in the fault tolerant container to operate in a redundancy manner, allowing a process fault tolerant system to manage the redundancy tasks to be respectively executed on redundancy hardware, controlling task synchronization, data comparison, error detection and restoring, and allowing all functional modules related to fault tolerant to be integrated to the core layer of the operation system. The high-end fault tolerant computers are mainly applicable to key fields such as banks and telecommunication, sensitive to system failure, and significant for guaranteeing system key process reliability. Common fault tolerant mainly rely on static structure redundancy principles, redundancy of a hardware layer is high in cost and complex to realize, and redundancy of an application software layer is not universal.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a process redundancy-based fault-tolerant system design method. Background technique [0002] With the wide application of computer systems in banking transaction processing, information services, financial computing and other fields, the requirements for the reliability of computer systems are getting higher and higher. As an important means to improve the reliability of computer systems, the meaning of fault tolerance means that the computer can still correctly execute the specified algorithm in the case of internal failures in the system. High-end fault-tolerant computers are mainly used in key fields such as banking and telecommunications. They are extremely sensitive to system failures, and it is very important to ensure the reliability of key processes in the system. Common fault-tolerant mechanisms are mainly implemented based on the principle of static stru...
