ABSTRACT:
A cross-bar switch includes a set of input ports and a set of sink ports in communication with the input ports. The input ports receive packets, which are snooped by the sink ports. The cross-bar switch also includes a set of port address tables. Each port address table is adapted to store data identifying a plurality of destinations supported by a sink port. For example, a first port address table is adapted to identify a plurality of destinations supported by a first sink port in the set of sink ports. When determining whether to accept a packet, a sink port considers whether the packet's destination is identified in the sink port's port address table. By supporting multiple destinations, a port address table implicitly facilitates a sink port's multicast operation.
