Abstract

Methods and devices useful in high-speed scalable switching systems include a memoryless switch fabric, per virtual channel queuing, digital phase aligners, randomized and complement connection modes, a mid-point negative acknowledge and output negative acknowledge scheme among other elements. A particular implementation of a routing table and switch element is described in part to illustrate the various techniques and devices of the invention.
