Abstract:
An apparatus for implementing an asynchronous transfer mode switch network, said apparatus comprising:an input buffer for storing input cells;an input switch network having a predetermined number of unit switches and having input ports and output ports connected between the input ports and the input buffer, said input switch network performing a fetch and add function in which a number of cell input is added in a direction from the input ports to the output ports and an address of the input buffer is transferred in a direction from the output ports to the input ports according to the number of cell input added, said input switch network transferring the input cells to the input buffer for storage according to a result calculated from the fetch and add function;a routing table for storing routing information for routing the input cells;a routing controller for receiving the input cells stored in the input buffer and for outputting and controlling the routing of the input cells in accordance with said routing information from said routing table;routing switch networks, each having an input port, an output port and a predetermined number of switches, for switching and outputting the input cells;a cell splitter connected to the input ports of said routing switch networks for splitting and transferring the input cells outputted by said routing controller for provision to said switches; anda cell merger connected to the output ports of said routing switch networks for merging and outputting the input cells outputted by said routing switch networks.
