Zusammenfassung:This invention pertains to non-blocking switching networks, and more particularly, to Clos switch architectures. A novel folded Clos switch apparatus and method therefore for reducing the number of unemployed I/O terminals of a multistage Clos switching network by partitioning a crossbar switch to provide both the first (yth) and last (x−y+1th) stage of a multistage Clos switch where x is the total number of stages in the general case.
