A three-stage one-sided rearrangeable polygonal switching network

This paper proposes a three-stage rearrangeable polygonal switching network (PSN) for interconnecting one-sided input-output terminals. In comparing our PSN with a three-stage one-sided Clos switching network of the same size and with the same number of switches, we prove that rearrangeability of a PSN is better than that of a Clos switching network. Also, the switching efficiency of the PSN is explored.
