MESSAGE TRANSMISSION CONTROL MODELS FOR SPECIAL PURPOSE COMMUNICATION NETWORKS

Relevance of the study. In modern conditions of managing specialized special-purpose communication networks, the problem of adaptive control of message transmission in conditions of dynamic changes in the network structure, which can be caused by equipment failures, cyber attacks and other factors, is relevant. Ensuring reliable and uninterrupted operation of such networks is critical for the effectiveness of control systems. The subject of study. Models of message transmission control in special-purpose communication networks, namely hierarchical models with a variable structure, their interaction and coordination at different levels. The purpose of the study. Formation of a control model that allows adaptive change in the structure of the operational communication network, taking into account new operating conditions and the current position of discrete objects (message packets) in the network. The following results were obtained. A model base is proposed that includes three classes of models: task models, perception models and interpretation models. Two types of mappings for task models are formulated and their interrelations are described. The problems of coordinating the joint use of models of different classes are identified. The presented models allow to formalize the process of functioning of the communication network and its redevelopment in real time. Conclusions. The developed models allow to automate the process of managing the transmission of messages and changing the configuration of a special-purpose network, which increases the efficiency of management and the resistance of the network to the influence of negative factors, such as cyberattacks or equipment failures.
