Assessment of the sustainability of communication networks built on the basis of computer networks

The article is devoted to the problem of quantitative assessment of the sustainability of communication channels or, more precisely, the sustainability of communication between two neighboring network nodes built on the basis of computer technology. Here, in order to achieve more accurate results, the process of assessing the quality of communication is carried out by determining the probability of its break within one segment. To carry out the calculations, network segments that are popular in practice are considered, where a different number of devices and communication lines are used. For this purpose, the article analyzes various models of network segments and examines the assessment of their stability. In particular, the “ 1x1” model is considered, built on one network device on each side and a plurality of communication lines between them; a “1x2” model built using one network device on one side and two network devices on the other side with two communication lines; and a 2x2” model built using two network devices on each side and four communication lines. It also compares the ring topology of the network- the”1x1x1” network model consisting of three elements, with these segment models. Finally, the optimal structure of complex networks located over a large geographical area is proposed in terms of sustainability and efficiency.
