This article proposes an analytical method for determining the traffic characteristics of multi-service switching networks in elastic optical networks. The method takes into consideration the limitations of W-S-W (wavelength-space-wavelength) switching networks in the execution of multi-slot connections in line with the concept of elastic optical networks. The results obtained on the basis of the developed analytical model are compared with the results obtained from the simulation experiments for a selected structure of a switching network. The study confirms the high accuracy of the proposed model. The model can be used to optimize and evaluate the effectiveness of blocking optical switching networks.
