Investigation of the Reliability of Service Equipment in Communication Networks

The security of a communication system is the system’s ability to resist the external destabilizing factors and impacts, as well as the internal changes that can lead to emergency operation. The security according to the European Committee for Electrotechnical Standardization (CENELEC) is normally integrated under the conditions of reliability. The main objective of this study is the modeling of reliability of the communication service equipment, which is system with capability for performance recovery after failure. For this purpose, the method of Markov chains is used.
