“…The literature on the subject distinguishes multiservice systems with single-service traffic sources and multiservice systems with multiservice traffic sources [46]. In the case of the former type of a multiservice system, a single source of a given traffic class can generate one, strictly defined, traffic stream.…”

“…terminals related to only one type of service. Relevant investigations, originally initiated in [46], are then continued in [50,51]. Gła˛bowski and Sobieraj [50] proposes the PGB-R method for calculations of the point-to-group blocking probability in a switching network with multiservice traffic sources and a reservation algorithm, while [51] discusses the PGB-T method for the determination of point-to-group blocking probability in a network with multiservice traffic sources and threshold mechanisms.…”

“…The assumption in the adopted method is that inter-stage links will be modelled by the model of a fullavailability group without threshold mechanisms [46]. The influence of the threshold mechanisms introduced in output links on the structure of traffic in inter-stage links will be taken into account by a change in the number of traffic classes offered to inter-stage links.…”

“…Calls of particular service classes are generated by Erlang, Engset and Pascal traffic sources. Because of the multiservice nature of the traffic sources (the possibility to generate calls of a number of services by just one source), they are grouped into appropriate sets [46]. Another assumption is that each set includes a defined number of traffic classes that generate traffic streams of the same type (i.e.…”

“…The authors in [46] attempt to develop a new model of multiservice switching network in which a single source can generate different traffic streams that correspond to service classes related to the given source. In the model considered in the study, traffic sources correspond to real terminals (end devices) that support different types of services (e.g.…”

This article proposes a new analytical method of determining occupancy distribution and blocking probability in multiservice switching networks with admission control mechanisms and resource management mechanisms. The proposed method is a universal one, which allows for determining blocking probability using the same model, regardless of the type of admission control mechanisms and resource management mechanisms. The versatility of the method is demonstrated in the article for two selected mechanisms, i.e. a threshold mechanism and a resource reservation mechanisms. The switching networks under consideration are offered multiservice traffic streams, generated by the so-called multiservice sources, according to Erlang, Engset and Pascal distributions. The proposed method is based on a generalised way of determining traffic characteristics for inter-stage links of switching networks with resource and call management mechanisms. Particular attention is given to determining the influence of the introduced mechanisms in outgoing links of the switching network on the traffic properties of inter-stage links of the network. The results of analytical calculations are then compared with the results obtained in digital simulation for a number of selected switching networks.
