ABSTRACT:
A scalable switch, a system of switches and methods, configured to sense a carrier at the output of the respective switch. The invention intelligently, and dynamically, controls the connection of a respective switch input to a respective switch output as a function of a carrier being present, or absent, at a selected output. Alternatively, a control plane is adopted to make request to send and acknowledge clearance to send. These control methods operate on a step-by-step manner allowing fast and parallel connectivity to be established to connect a variety of interfaces, including Ethernet, PCI, SCSI, and FibreChannels. The present invention reduces switch cost, energy cost, and switch volume, while allowing scalability of connection requirements, reduction of delay, and promotion of green IT.
