Blocking probability in the multi-service switching networks with multicast traffic

Abstract

In this paper, a new approximate method of point-to-group blocking probability calculation in switching networks carrying a mixture of different multi-rate unicast and multicast traffic streams is presented. Special attention is paid to the methods for determining the effective availability parameter in the case of multicast connections. The results of analytical calculations are compared with the data of digital simulations of switching networks with unicast and multicast connections.
