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.
