Abstract:
1. A packet routing apparatus for relaying a packet, received from one of a plurality of ports to which the packet routing apparatus is connected, to another port, the packet routing apparatus comprising: at least one routing unit; at least one coupling mechanism, connected to the at least one routing unit; at least one port controller, connected to at least one port and the at least one coupling mechanism, the at least one port controller receiving a packet from one of the ports and transmitting the packet to the at least one coupling mechanism, and receiving a packet from the at least one coupling mechanism and transmitting the packet to one of the ports; and at least one extended function processing unit, connected to the at least one coupling mechanism, the extended function processing unit receiving the packet from the at least one coupling mechanism, executing a predetermined append function to the packet, wherein, when the at least one routing unit has received a packet from the at least one coupling mechanism, the at least one routing unit transmits the packet to the at least one port controller or the extended function processing unit through the at least one coupling mechanism.
