ABSTRACT:
Disclosed is a full access, non-blocking, wide band switching network that is self routing. Responsive to input signals having embedded destination addresses, the self routing switching network comprises a conventional self routing sorting network followed by a self routing expander. Incoming signals are ordered, and simultaneously appear at the output of the sorting network in ascending order of destination addresses. The signals incoming to the expander network are also processes simultaneously. The processing consists of relating the intermediate address of the expander network input line at which each signal appears with the destination address of the signal, and steering the signal to the appropriate output line in accordance with said relating.
