Method of Providing Rationale for Reasonable Number of Backup Comunication Channels in Information & Telecommunication Network

The article considers a method of rational selection of the composition of backup communication channels to increase the sustainability of the network with the account of hostile action results intended for providing a rationale of reasonable number of backup communication channels between communication hubs. To do this, the authors use a logical and probabilistic method implemented with the help of the orthogonalization of the network structural function.
