| Popis: | The effectiveness of the functioning of telecommunication systems, which belong to the class of complex technical systems, depends on the reliability of its subsystems and elements, as well as the complexity of the relationships between them. The aim of the article is to substantiate a general approach to a comprehensive assessment of the reliability of telecommunication equipment telecommunications network with a reducible structure with the development of a methodology for calculating equipment reliability indicators. This article presents a formal description of a scientific problem and offers a general approach to solving the problem is based on the use of the decomposition principle, which allows a phased assessment of the reliability of a telecommunication network at three interconnected levels: the first stage is at the level of individual equipment elements (such typical devices as routers, switches, servers, workers stations, IP-encryption equipment, etc.), in which various types of redundancy can be provided separately or jointly: structural, load, temporary; the second stage – at the telecommunication equipment level of information paths (routes); the third stage is at the telecommunication equipment level of information areas, which are a combination of equipment of various paths. Methodology for solving the problem. A technique has been proposed for a comprehensive reliability assessment of telecommunication equipment of communication networks with a reducible structure, taking into account a combination of factors, some of which are aggressive and lead to a decrease in reliability (failures causing short-term interruptions in operation; steady equipment failures that need to be restored to serviceability of failed devices in a repair body ; insufficient qualification of the attendants), and others – support the normal functioning of the telecommunication equipment in at the given level |
