Problems solved by technology

[0005] However, the current evaluation model of distributed software focuses on the reliability of distributed software, and rarely reflects the characteristics of time constraints; at the same time, the indicators used in reliability evaluation are usually single, that is, each evaluation is only for software A certain performance index of reliability is evaluated

Abstract

The invention relates to a distributed software reliability evaluating system with time constraint, comprising of reliability evaluator on the main control terminal, simulator on each node machine in the distributed system and distribution software simulator. The reliability evaluator is used for receiving configuration file and doing original configuration, controlling simulation of simulator to the node machine; the simulator is used to received test information sent from the reliability evaluator, and executable program and data file from the simulator of the distributed software; the simulator of the distributed software is generating program in program listing and data file in file program listing and distributing them with random to simulator of node machine.

Description

technical field [0001] The invention belongs to the field of software performance evaluation and provides a new model and method for reliability evaluation of distributed software with time constraints. Background technique [0002] In recent years, with the rapid development of science and technology, microelectronics and computer technology have begun to penetrate into various fields, and the application of electronic information technology has entered a new period of rapid development. Due to the time-constrained distributed software system has the characteristics of time constraints on the one hand, and the redundancy of programs and data files on the other hand, it is widely used in the fields of military, aerospace, navigation and energy control. As a part of the computer system, the distributed software with time constraints, with the expansion of the scope of application, its scale is also expanding, the function is increasing, and the complexity is deepening, and it...
