Evseeva O. Methods of adaptive routing in hybrid telecommunication networks with guaranteed quality of service

The object of research - processes of routing in telecommunication networks (TN). The purpose of work - increase of efficiency of functioning TN with guaranteed quality of service. The methods of research include the mathematical tools of the differential-difference equations of a condition, theory of optimum control, theory of hierarchical multilevel systems, mathematical tools of operations research, and also methods of imitating modeling. Results of work are dynamic model of routing in space of conditions, which in work has obtained the further development. The novelty of model consists in formalization of processes of guaranteed quality of service in hybrid ТN by the account of a possibility of realization within the network of various routing strategy (static and dynamic) and various modes of package switching according to a type of the users traffic and their requirements to a level and guaranties quality of service. In work methods of hierarchical - coordination routing in ТN of WAN-level with hierarchical structure also are developed. Novelty of the methods consists in use various decomposition principles at levels of decomposition on subnet and on time variable: accordingly principles of interaction prediction and purpose coordination in the routing method IP-PC and principles of interaction estimation and purpose coordination in the routing method IE-PC. The materials of the dissertation are introduced in research №129-1 (department ТS KNURE, state registration №0101U005126), where there were used results on development of a routing method in perspective ТN, and in research „Smuga-KhDRNTC" (Kharkov State Regional Scientific and Technical Center of Technical Protection of Information), where the results of the author on generation of the requirements to methods of routing in modern ТN are used. The materials of the dissertation are used in educational process KNURE. Area of application is telecommunication.
