Abstract

At present, in all areas of life, the rapid development of information technology, which needs high-quality and fast exchange of information, needs data networks. The technical parameters of these networks must be studied accurately enough to design and develop new local computer networks. The task of investigating the reliable operation of these network parameters is the most urgent in the field of information technology. Therefore, common topologies of local computer networks and reliability models of recoverable systems are considered in the article. The Formulas for calculation of complex reliability indicators of the considered topology are given. The corresponding example is shown. For this, the Markov service model, that is, the description of a mass service operation using a Markov process with a discrete set of states, was used. This paper describes results that can improve the hardware reliability of local data communication networks in the design and modernization of existing technical systems.
