Розглядається завдання забезпечення ефективного функціонування телекомунікаційних мереж (ТКМ).
Від того як функціонують ТКМ установи залежать критичні аспекти його діяльності. Найперспективнішим
напрямком розвитку закритих мереж є перехід від орендованих каналів зв'язку до відкритих каналів мережі
Інтернет. Однак використання відкритих Інтернет мереж призводить до загроз інформаційної безпеки.
Розроблені методи оцінки захищеності об'єктів мережі від загроз інформаційної безпеки засновані на якісній
експертній оцінці. Проведено удосконалення в переході до кількісної оцінки ефективності функціонування ТКМ на
підставі критеріїв доступності інформації і послуг зв'язку.
The article deals with the task of ensuring the efficient functioning of telecommunication networks. From the functioning of the telecommunications network of the closed network of the educational institution, the critical aspects of its activity depend, the task of ensuring the effective functioning of the network is extremely acute. The most promising direction of the development of corporate networks that can meet the growing needs of private networks is the transition from using their own or leased communication channels to open, built with the use of the Internet or other networks. However, the use of open Internet networks is accompanied by the fact that they are exposed to the impact of specific for open telecommunication networks threats to information security, which affects their performance. The methods of assessing the security of network objects from threats of information security developed to this moment are based on qualitative expert evaluation. Their improvement is offered in the part of the transition to a quantitative assessment of the efficiency of telecommunication networks functioning on the basis of the criteria for the availability of information and communication services. Mathematical modelling, as well as natural experiments and statistical research methods are used to solve the problems. Experimental verification was carried out by conducting field experiments, using hardware and software used on communication nodes of the investigated network. The proposed method allows to evaluate the efficiency of the functioning of the corporate telecommunication network with the formation of the result of evaluation in the form of a quantitative indicator, thereby increasing the quality of the assessment. The software developed during the study is designed to quantify the performance of the network elements. As a result of this analysis, it is possible to use the mathematical and methodical apparatus of the theory of reliability for the analysis of the structural reliability of complex telecommunication networks. As an indicator of the efficiency of functioning of networks and their elements, Kg is chosen as the normalized reliability index of telecommunication networks and their elements. Thus, the possibility of increasing the efficiency of network operation by topological methods is substantiated.
