Abstract:
The paper presents the results of a simulation study on multi-rate three-stage Clos switching networks with additional inter-stage links. Switching networks in which a system of overflow links was provided for the first, second and the third stage are investigated. Additionally, different structures of connections between inter-stage links are discussed. The investigation has proved that an application of overflow systems is followed by a substantial decrease in the internal blocking probability in the switching network. An appropriate capacity of overflow links can even result in a virtually complete elimination of internal blocking. This paper proves that the best results are obtained with the introduction of overflow links to the first stage of the network, both in the case of point-to-point and point-to-group selection.
