EN This paper presents a new approximate calculation method of the occupancy distribution and the blocking probability in switching networks which are offered multi-service traffic streams generated by a finite population of two-state sources. The proposed method belongs the class of methods known as the effective availability methods. The basis of the proposed calculation algorithm is the occupancy distributions in interstage links as well as in the outgoing links (forming outgoing directions). These distributions are calculated with the help of the full-availability group model and the limited-availability group model. The results of analytical calculations of the blocking probabilities are compared with the simulation results of three- stage switching networks with infinite source population, and, therefore, the validity of the assumptions used in the model is proved.
