THE RELIABILITY ASSESSMENT OF LOCAL COMPUTER NETWORKS USING A MARKOV MODEL OF MULTIPLE HETEROGENEOUS SWITCH GROUPS

Terskov Vitaly, Sakash Irina

During the rapid development of information technology, it is impossible to exchange information without data transmission networks. Consequently, the design and development of new local computer networks requires an accurate analysis of their technical characteristics and on this basis remains one of the most urgent tasks in the field of information technology. Therefore, the article considers common topologies of local computer networks and models of reliability of restored systems, and also gives formulas for calculating complex reliability indicators of the topology in question. Relevant examples are shown. To do this, the Markov service model was used, that is, a description of the queuing operation using a Markov process with a discrete set of states.
