Orlov Y. Methods of analys and optimization of systems management Software Defined Networks (SDN)

The thesis on the degree of Candidate of Engineering Sciences, specialty 05.12.02 - Telecommunication systems and networks. - State University of Telecommunications, Kyiv, 2015. The thesis is devoted to development of methods of the analysis and optimization of parameters of a control system of network streams of Software Defined Networks (SDN). In work the principles of creation of the telecommunication networks possessing ability to self-organization are investigated. The method of multicriteria optimization for determination of parameters of Software Defined Networks which consists in receiving the resultant criterion function used for calculation of a priority of a network traffic at the organization of management of network streams with automatic detection of priorities is improved. The option of creation of a control system of network streams with automatic detection of priorities of network packages realized by dynamic change of tables of network streams in the course of which for each record the priority on ToS byte is set is offered. The technique of determination of parameters of optimum system of transfer to the managing director of information on two indicators of quality with application of conditional criteria of advantage is offered. The model of controlled object by means of decomposition methods is developed. The technique of the functional description of model of development of Software Defined Networks on the basis of the theory of the conflicts is offered and recommendations of rather optimum choice of system of the equations for the most evident understanding of the nature of the conflict inside and outside the network are provided.
