A new approach to modeling behavior of SDN-based networks is proposed in the paper. The main feature of the proposed approach is the ability to modeling boundary meanings of quality of service characteristics of Software-Defined Networking, taking into account the dynamic change network infrastructure and particular services degradation and subsequent analysis of the results based on mathematical apparatus of the theory of network calculus. In accordance with the basic principles of network calculus theory formed mathematical model of Software-Defined Networking infrastructure functioning, the analysis of temporal parameters of the process of service delivery. Examples of modeling the behavior of commutation element of Software-Defined Networking, taking into account the intensity of incoming requests, as well as various methods of data transfer, with aggregation and without aggregation of data flows, are also proposed in the paper.
