Abstract
The paper treats the blocking problem in banyan multistage interconnection networks. After presenting the specific features of banyan networks the author describes some known solutions for the decrease of the blocking probability. A new solution is described which ensures the decrease of the blocking probability without the important increase of the cost imposed by the other solutions. The name proposed by the author for this new network is the passing banyan network. Next the blocking probabilities of a unique connection in the normal, the p – replicated, the p – dilated and the passing banyan networks are calculated and a comparison among them is performed. The conclusions which result from the comparison are presented.
