Methodology for a comprehensive assessment of the quality of telecommunication services of transport networks using SDN/NFV technologies

Methodology for a comprehensive assessment of the quality of telecommunication services of transport networks using SDN / NFV technology has been developed. This methodology can be the basis for selection the structure and number of SDN controllers and their optimal location in the communication network based on SDN/NFV, calculation reliability indicators, obtainment loss probabilities of streams and control messages as well as time delays for processing streams in SDN telecommunication equipment. Proposals were also given on balancing the traffic load on SDN controllers of the communication network.
