Systems and methods for efficient transmission of packets within a network communication device are described herein. Some illustrative embodiments include a network communication device that includes a plurality of ports (each port configured to communicate with one or more network devices), and a bus coupling the plurality of ports to each other (the bus providing a shared path for one or more bus transfers originated by a first port of the plurality of ports, and the one or more bus transfers including information). The bus includes a plurality of port map bits, a port map bit of said plurality of port map bits corresponding to a second port of the plurality of ports. The second port is configured to forward the information to the one or more network devices if the port map bit is asserted.
