Abstract

A multicast concentrator to both concentrate and multicast packets, and the concomitant self-routing control mechanism for the switching of the packets in the multicast concentrator. An m-to-n multicast concentrator always guarantees that the total number of 0-bound and bicast signals routed to its 0-output group and the total number of 1-bound and bicast signals routed to its 1-output group are both the maximum possible. An m-to-n multicast concentrator can be easily adapted from an m-to-n concentrator by replacing each of the sorting cells in the concentrator by a bicast cell.
