Modelling of switching networks with multiservice traffic by the IPGBMT method

Abstract

This paper presents a new analytical method for approximation of blocking probabilities in multiservice switching networks with point-to-group selection. The method is based on the classic PGBMT method which has been adequately modified to improve the accuracy of the final results. In order to estimate and verify the correctness of all theoretical assumptions adopted in the study, the results of the analytical modelling are compared with the results of the digital simulation and the results obtained by the classic PGBMT method in a number of selected three-stage multiservice Clos networks.
