This article presents an approximate method of blocking probability calculations in a switching node of virtual circuit networks carrying a mixture of different traffic streams, including multicast traffic. This mixture can be composed of an arbitrary number of unicast and multicast traffic classes generated by a finite population of two-state sources (pseudo-random traffic). It is assumed that outgoing directions node consist of links of various capacities. Hence, the model enables calculations of blocking probabilities for calls of all traffic classes for any structure of the groups forming the outgoing directions. The proposed method is based on an approximation of the service process occurring in outgoing directions by appropriately constructed one-dimensional Markov chain. The analytical results of the blocking probabilities in sample switching nodes are compared with the simulation results.
