ABSTRACT:
Queues which correspond to each of the LANs in multiplexed virtual LANs are created. Received packets are distributed to the queues in accordance with a VLAN-ID and a destination address included in each of the received packets. The packets are output from the respective queues in a predetermined order, thereby ensuring fairness among the virtual LANs. As a result, even if a user of a virtual LAN transmits data with traffic having a wide transmission band, the virtual LAN does not occupy the band of the physical port and does not hamper transmission of other users.
