In a packet relay apparatus equipped with a hierarchical bandwidth control function, a queuing unit of a bandwidth controller for controlling a bandwidth of a packet to be transmitted recognizes user information for identifying a user from VLAN ID of a received Tag-VLAN packet, acquires queue information representative of a queue position by referring to a priority mapping table by using a user priority order in the packet, and queues the packet to the queue identified by the user information and queue information. Bandwidth control can therefore be performed without searching a QoS information management table.
