Research On The System Reliability Of Computer Network And Application To Mines

With the rapid development of computer technique and network technique, people's demands of information are more and more. As the high-way and main carryer of information, the reliability of computer network has been paid more and more attention to.This paper describes the research on system reliability of computer network deeply. Its main contents and analyze are as fellows.First of all, this paper analyzes the research state at present and the advantages or disadvantages of the reliability research in computer network. Then the paper gives the necessity for applying the system reliability and system reliability engineering to computer network.Secondly, this paper introduces the develop steps, work principle and layer model of computer network, while puts forward a new layer model for analyzing the risk of computer network, then doing some analysis.Next, this paper introduces the definition, trait, principle of system and system engineering simply. Then the paper analyzes the definition, develop steps, measures and common model of system reliability, while introduces the definition of system reliability engineering.Next, according to the idea of system engineering, this paper analyzes and designs the reliability of computer network system from six aspects, such as network topology, network device, network routing, network operation, network business and network management deeply and detailed. With this base, this paper analyzes and studies the framework of evaluation measures, approaches, simulation technique and relevant mathematics models of computer network system's reliability. Additionally, this paper discusses the management of reliability for computer network deeply.Finally, this paper applies the study to the computer network system of JinDuicheng mine system. According to the characters of computer network system in mine, the paper analyzes and studies its reliability elaborately, and then evaluates the framework of evaluation measures in reliability aspect.
