Point-to-group blocking probability in switching networks with multi-service sources and bandwidth reservation

This article proposes a new analytical method for the determination of traffic characteristics in multi-stage switching networks with multiservice traffic sources and implemented reservation mechanisms. The method proposed in the article provides a set of well-defined actions which can be performed to determine the point-to-group blocking probability in switching networks with resource reservation in which each single traffic source can generate calls of different service classes. The results of the analytical calculations of the point-to-group blocking probability are compared with the results yielded during the simulation experiments. The simulation results indicate high accuracy of the proposed method. The simulator was written in C++ using object-oriented programming.
