The article defines and substantiates the method of reserving the structure of the information transmission channel of the telecommunications network, provided that the reliability characteristics of the basic main element of the channel are taken into account. The parameters and characteristics that are taken into account in the process of evaluating the reliability of the reserved information transmission channel of the telecommunications network have been systematized.
The model for assessing the reliability of the information transmission channel, taking into account the reliability parameters of the main basic element, has been developed and presented.
The presented model is based on probabilistic reliability characteristics of the basic element of the telecommunications network with redundancy. It takes into account the probabilities of fault-free operation of the main and backup element, the probability of switching from the main to the backup element in a set time, and the probability of the serviceable state of the data transmission channels to the base element. Wireless radio communication is one of the most dynamically developing areas of telecommunication networks widely used in solving economic issues. A complex property that characterizes the quality of functioning of telecommunication networks based on wireless communication is its reliability. Solving the problem of assessing the reliability of an information transmission channel, as one of the structural components of telecommunication networks, whose work is based on the functioning of the main basic element of telecommunication networks, taking into account its reliability indicators, is a timely scientific task, the solution of which is devoted to this article.
The results of the evaluation of the probability of a healthy state show that the probability of a healthy state for the selected range of reliability of basic elements and communication channels lies in the range of 0.9 - 0.99 and its tendency to increase with increased reliability of the constituent elements of the telecommunication network structure with redundancy.
