ABSTRACT:
A rearrangeably nonblocking multicast network 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≧n1+n2. The network has all multicast connections set up such that each multicast connection passes through at most two middle switches to be connected to the destination outlet links.
