Methodology for assessing the current state of the engineering telecommunications infrastructure of a special-purpose communications network segment

The article proposes a methodology for assessing the current state of the engineering and telecommunications infrastructure of a special-purpose communication network segment and tested it by the example of the regional segment of the integrated multiservice telecommunications system of the Ministry of Internal Affairs of Russia. A regional segment of a special-purpose communication network is defined as a physical or logical zone in which granting access to resources or the denial of this access are regulated by access rules and control mechanisms. Such zone has a clear boundary with other segments. Taking into consideration the need to maintain state operability of the regional segment of a special-purpose communication network, the task of assessing the current state of the engineering and telecommunications infrastructure is relevant. The paper proposes a sequence of actions aimed at conducting an audit of communication nodes at all levels of the regional segment including engineering infrastructure, telecommunications equipment, data transmission channels. As a mathematical apparatus, mathematical methods for processing expert assessments, associated with determining the significance of individual components of engineering and telecommunications infrastructure, are used. The method of hierarchy analysis with the involvement of expert groups is applied to define the significance coefficients of the factors accounted for when calculating the integral evaluation functions of the regional segment of a special-purpose communication network.
