ABSTRACT:
A three-stage network is operated in strictly nonblocking manner and includes an input stage having r1switches and n1inlet links for each of r1switches, an output stage having r2switches and n2outlet links for each of r2switches. The network also has a middle stage of m switches, and each middle switch has at least one link connected to each input switch for a total of at least r1first internal links and at least one link connected to each output switch for a total of at least r2second internal links, where m≧2*n1+n2−1. In one embodiment, each multicast connection is set up through such a three-stage network by use of at most two switches in the middle stage.
