Abstract
This article proposes a simplified approach to the internal blocking probability calculation in switching networks with mechanisms controlling resource allocation for offered multi-service traffic streams. This resource allocation control can be executed using the so-called threshold and resource reservation mechanisms, according to which the volume of resources admitted depends on a traffic class and on the occupancy state of the interstage and outgoing links of the switching network. The developed method is of generic nature and allows one to model switching systems regardless of the implemented resource allocation control mechanism. However, despite its generic character, the method provides better accuracy as compared to the methods worked out earlier.
