Abstract: The present invention is to provide an Ethernet switch fabric controller requiring output port buffer unit of less capacity while still working with an Ethernet switch to smoothly forward the packet from each input port of the Ethernet switch to an output port corresponding to the packet header at the input port. It is featured by the use of proper number of temporary buffer units each of proper length, and output port buffer unit of proper length.

Abstract: A digital data exchange device, used for the dynamically electrical connection of a plurality of input ports to a plurality of output ports, which comprises: a first multiplexer, electrically connected to the plurality of input ports, used for selecting an input port to output data of the selected input port, wherein the data contains an output port ID; a demultiplexer, electrically connected to the first multiplexer and the plurality of output ports, used for selecting the output port based on the output port ID to output an input port ID to the output port; an address generator, electrically connected to the multiplexer and the demultiplexer, for sequentially generating the input port IDs of the plurality of input ports. This allows the first multiplexer to select the appropriate input port, so that the input port ID is transmitted to the output port by using the demultiplexer, thereby electrically connecting the input port to the output port.
