Abstract
A packet switch for switching packets received on a number of incoming packets channels to a number of outgoing packet channels. The packet switch includes a number of packet buffers each for storing packets received from an associated one of the incoming packet channels and further includes a number of selectors each permanently connected to each of the packet buffers and each associated with one of the outgoing packet channels for selectively connecting any of the packet buffers to the associated outgoing packet channel. A packet switch control mechanism responds to packets stored by the packet buffers by controlling the selective connections made by the selectors based on headers included in the stored packets. The control mechanism also responds to the stored packets by selectively effecting the transmission of the stored packets by the packet buffers.
