ABSTRACT:
A LAN switch includes port modules which receive frames from their respective LAN segments and forwards the frames simultaneously to all output ports and to a port look-up function which determines the output port to which the frames should be forwarded. If the port look-up function identifies the output port, frame transmission is halted at all ports except the identified port. By performing the forwarding function and port look-up function simultaneously, a zero latency switch is provided.
