ABSTRACT:
Improved throughput is realized in a packet cross-connect switch by including an addressable memory unit in each of a plurality of input ports for storing packets and by allowing each of a plurality of output ports to address directly any one of the input ports to obtain a particular packet stored therein, which is destined for the output port. To this end, the input ports supply the packet destination and starting address of the packet stored in their memory to a scheduler. The scheduler controllably selects an output port assigned to the packet destination and supplies packet output information to the selected output port including the packet starting address and the identity of the input port storing the packet. When a particular output port is ready to obtain a particular packet, it addresses the memory unit in the particular input port to read the first packet word. The addressed packet word is supplied via a data bus to the requesting output port. Thereafter, the packet address is incremented by one packet word at a time and the corresponding packet words are read out of the input port memory units until the entire packet has been supplied to the requesting output port.
