It was believed that, for strictly nonblocking multicast and broadcast interconnect operations to be achieved, a switching network had to have a minimum of N2 switching states, i.e., a crossbar-type switch. A novel system concept that reduces the switching complexity while maintaining nonblocking multicast networking is proposed and experimentally demonstrated.
