Abstract

Today, the equipment of electronic communication networks (EECN) consists of two interconnected components. The first is hardware, the second is software, the normal functioning of each of which depends on the functioning of the network in general. One of the main concepts characterizing the network's ability to perform tasks as intended is functional safety (FS). This concept is similar to the concept of reliability, but differs mainly in that in the context of reliability, all possible failure situations are considered, and when considering FS, only those that lead to the failure of the certain system functioning. Failures are divided into four categories: detected safe and dangerous, undetected safe and dangerous. From the point of view of FS, only undetected dangerous ones are considered and constitute threats. According to the number of dangerous undetected failures, there are four levels of security completeness. The article also considers the main international standards, which provide definitions and quantitative characteristics of the main parameters of FS. So, the main parameters of FS include the system availability ratio, the average time to failure, and the probability of a dangerous undetected failure. At the same time, the mathematical apparatus of reliability theory can be applied in the analysis of FS. At the same time, the hardware component of EECN is quite widely researched, and the software component needs further study. Also, the FS of the software component is affected by a number of factors, both external and internal. The further task consists in the formation of methods and measures aimed at eliminating or reducing the impact of influencing factors. Also, since various types of software, mainly system software, are widely used in EECN, it is necessary to focus further research on it.
