Currently, to ensure flexibility and reliability in managing computer networks, software-defined networking (SDN) technology has gained widespread popularity.The paper considers the problem of dynamic routing in a SDN with ensuring the quality of network service. A mathematical model of SDN is proposed to ensure quality of service based on fuzzy logic. Service quality is considered as a set of fuzzy values of communication channel parameters that satisfy a given quality criterion. The aim of the work is to develop a modified algorithm for paired transitions to ensure the quality of network service based on fuzzy logic. The work created a rule base for a fuzzy inference system to approximate the quality of service function and developed a visual environment FuzzySDNDesigner for studying dynamic routing processes in a SDN
Key words: : software defined networks, paired transitions algorithm, fuzzy logic, fuzzy inference, visual environment FuzzySDNDesigner, quality of service.
