ABSTRACT:
A transmit packet generated by a CPU1is held in a buffer100a(100b). From among packets received from Ethernet820a(820b), a packet, a destination of which is a communication device800, is held in the buffer100a(100b). A packet which should be transmitted is transmitted from a transfer judging circuit200to Ethernet820aor820bthrough a MAC unit300aor300b. If a transfer judging circuit200judges a packet from the Ethernet820ato be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet820bthrough MAC300b. If a usage rate of a transferring FIFO buffer130a(130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer120a(130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet820aor820bin preference to the transmit packet. This prevents a transfer buffer means from overflowing.
