Point-to-Group Blocking in 3-Stage Switching Networks with Multicast Traffic Streams

Abstract

In this paper we propose a new approximate method of effective availability for calculating the probability of point-to-group blocking in multi-stage switching networks with unicast and multicast connections. The results of analytical calculations of the probability of blocking are compared with the results of discrete events simulations of the switching network with multicast and unicast connections. The present analytical study has confirmed the correctness of all theoretical assumptions and fair accuracy of the analytical method proposed.
