Abstract
Application of the technique of statistical line grouping to banyan-type networks to practically alleviate the problems of output contention, traffic fluctuation, burstiness, and so forth without incurring additional preprocessing and buffering on the input traffic by introducing alternate-routing ingredient to the unique-routing banyan-type network, but without complicating the switching control too much through alternate routing. The multicast concentrator, a concentrator with the capability of multicasting, composed of interconnected bicast cells is employed to fill in each of the dilated nodes of the banyan-type network to give a hybrid network. An extremely simple self-routing control mechanism over the hybrid network which is the natural melting of the self-routing control inside the multicast concentrators and the self-routing control over the banyan-type network is presented.
