- TITLE: INVESTIGATION OF THE RELIABILITY OF THE CABLE TELEVISION HEADEND USING A MARKOV PROCESSES
- ABSTRACT: 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 reliability of various kinds of obj ects (components, systems, devices, products, etc.) is investigated by applying established in the science and practice approaches, methods and means. They differ depending on what mathematical approach for modeling and processing of results is used, on what kind of object they are addressed (analog, digital or mixed), how the faults are defined, only the safety assessment after failure is evaluated or just the reliability etc. The main objective of this study is the modeling of reliability of the cable TV headend, which is system with capability for performance recovery after failure. The method of Markov chains is used for this purpose.
