Abstract
The reliability of distributed network is researched by establishing one set of effective modeling, analysis, evaluation, and optimization method theory, which is a hot research area in the distributed network system field. The phased analysis method is utilized to study the reliability of the distributed network including the analysis and definition of the distributed network on the basis of studying its operational process. Meanwhile, task request, task scheduling, and execution phase will be also studied, and the establishment of reliability mathematical model of distributed network will be discussed to provide actual reference significance for the design of the distributed network system.
Highlights
Distributed network is a system based on a common network to provide software services
It has a high degree of cohesion and transparency. e difference between a distributed network and a common network lies in the difference of high-level software
There is a layer of software middleware on top of the distributed network operating system to implement this model. e World Wide Web is such a familiar distributed network
Summary
Distributed network is a system based on a common network to provide software services. Because machine fault, network disconnection, and process termination resulted by priority use of remote host on local computing resources, the unavailability of computing nodes of the distributed network occurs commonly. Fault management technology plays an important role in improving the reliability of the distributed network and ensuring the performance of services, the use of fault management technology will inevitably increase the power consumption of a data center, bring additional operating costs to distributed network service providers, and reduce the return on investment. Erefore, while ensuring the reliability of the distributed network, how to reduce the energy consumption of data centers is a problem that must be considered when designing fault management technology. The research results obtained through the analysis of sensibility of reliability parameters in the distributed network system in this paper can provide reference bases for how to improve system service reliability when designing the distributed network system
