<p>A local area network switch (10) includes input and output ports (RPO-RPO23 and TPO-TP23, respectively) for receiving and transmitting broadcast and unicast data transmissions from and to corresponding network stations (30, 98) and a crosspoint switch (12) for forwarding incoming broadcast and unicast data transmissions to the crosspoint switch (12). Each output port has a unique unicast link to the switch (12) for receiving unicast transmissions directed solely to its corresponding network station. All output ports also share a second broadcast link to the crosspoint switch for receiving broadcast transmissions directed to all network stations. The switch (12) routes each unicast transmission from an input port only to the appropriate output port via the output port's unicast link and routes broadcast transmission from an input port to all output ports via the common broadcast link.</p> |
