Abstract
A method and apparatus for a high speed asynchronous transfer mode switch is provided which includes an input buffer circuit coupled to communication lines for receiving and temporarily storing packets from the communication lines, a switch comprising one or more planes and output circuitry for coupling the switch outputs to respective communication lines. The switch is comprised of a plurality of switching elements, each of which include a sorter for ranking packets responsive to addresses associated with the packets, compare circuitry for receiving the ranked packets from the sorter and passing up to a predetermined number of packets having the same address, and routing circuitry for routing the packets passed by the compare circuitry responsive to the associated addresses. After a packet is successfully transferred through the switch, an acknowledge signal is returned to the sending input buffer circuit.
