Abstract:
1. A switch for transmitting data from a first device to a second device, comprising: output segments comprising output ports in communication with the second device, the output segments comprising buffers; input segments which receive slices of data from the first device: queues which store the slices of data; circuitry for selectively outputting a slice of data from a queue to an output segment for transmission to the second device; and a bus over which the first device communicates with a third device, the first device communicating to the third device that the first device controls an output port thereby preventing the third device from transmitting data to the second device via the output port; wherein the input segments broadcast receipt of new data to the output segments, and the output segments buffer information relating to the new data following broadcast in order to keep the output segments in synchronism.
