Abstract
<jats:p>The article investigates the current problem of controlling access to resources of the fifth generation optical transport network (5G), which is an important component of the infrastructure of modern telecommunication systems. In conditions of rapid growth in the number of connections, traffic heterogeneity and dynamic load changes, traditional access control algorithms lose their effectiveness and are unable to provide the necessary level of accuracy. In order to increase the flexibility of decision-making, the article proposes the use of fuzzy logic to develop an intelligent access controller capable of operating in conditions of uncertainty and incompleteness of input data. The simulation results confirm the advantages of the proposed approach.</jats:p>
