Nevzorova O. Models and methods of hierarchical-coordination routing in software-defined telecommunication networks

Object – processes of hierarchical routing in software-defined telecommunication networks. Purpose – increasing the scalability of routing solutions in software-defined telecommunication networks by improving the models and methods of hierarchical-coordination routing. Methods – graph theory, set theory, optimization methods of mathematical programming, mathematical tools of operations research, theory of multilevel hierarchical systems optimization, and methods of a laboratory experiment. Results – the improved flow-based model and method of hierarchical coordination of intra-area source routing in the SDN/MPLS-TE network; for the first time a mathematical model and method of hierarchical-coordination inter-area routing in a software-defined telecommunication network have been proposed; for the first time a three-level hierarchical coordination routing method in SDN/MPLS network has been proposed; a two-level routing method with the link resources allocation in the SDN/MPLS-DiffServ-TE network has received further development. Introduced – in the educational process of the Kharkiv National University of Radio Electronics; in scientific research №299-1 (№ DR 0115U002432) «Increasing the scalability of technological decisions concerning maintenance of the quality of services in convergent telecommunication systems»; in the activity of the enterprise LLC «Telecommunication systems»; in the activity of the enterprise LLC «Euro-Utrejd» in the development of network equipment software of modern multiservice telecommunication systems. The patent for a utility model has been obtained. The field of use is telecommunication systems and networks
