Approach to Estimating the Probability of Providing “Cloud” Services in the SDN

The subject of the study is “cloud” services that are provided to customers in software-defined networks. The purpose of the work is to offer mathematical software for calculating the channel resource when implementing a “cloud” service at the client's request and assess the possibility of providing it, taking into account the specifics of software-defined networks. The methodological basis of the work is made up of methods of theoretical analysis, mathematical modeling and method of generalization. The mathematical model is based on a proven method of sifted load for a multiservice network. Mathematical modeling was carried out for a generalized network structure using the MATLAB mathematical package. The results were obtained for the most frequently used number of channel units (from 1 to 10) and different network load, which makes it possible to put the proposed method into practice. Based on the results of an experimental study, conclusions and recommendations are made.
