Abstract
A switch having a plurality of input/output (I/O) ports and a crossbar device programmably coupling a first of the I/O ports with a second of the I/O ports. A plurality of port request controllers (PRCs) are coupled such that each PRC is associated with one of the I/O ports. A plurality of serial request busses are arranged such that each serial request bus couples each PRC with its associated port. A plurality of serial response busses are coupled such that each serial response bus coupling each PRC with its associated PRC. In operation, the serial request and response busses operate independently in a non-blocking fashion to process connection and clear requests in parallel.
