<p>A packet classification part 39 classifies input packets into a transparent packet, a management packet, etc. The transparent packet is sent to a transmission priority control part 51 through the packet classification part 39 and an output packet sorting part 46. The management packet is sent to a management control part 45 through a packet authentication part 44 and the output packet sorting part 46. After decoding the management packet, the management control part 45 outputs a transmission packet for management communication. The transmission packet for management communication is sent to the transmission priority control part 51 through the packet sorting part 46, a transmission packet authentication processing part 49, and an authentication packet generation part 50. The transmission priority control part 51 transmits the transmission packet for management communication, giving priority to it over the transparent packet.</p> |
