<p><P>PROBLEM TO BE SOLVED: To provide a relaying apparatus and a packet relaying method that perform congestion control for each virtual network. <P>SOLUTION: Each transmission port module includes a plurality of queues in association with combinations of a priority and a VLAN number. An accumulated-amount storage unit 157 stores a total size of packets accumulated in queues associated with the same priority. A threshold storage unit 158 stores a threshold of a total packet accumulated amount for each queue. When a packet is received, whether to discard the packet is determined based on a total packet accumulated amount stored in the accumulated-amount storage unit 157 in association with a priority set for the packet and the threshold stored in the threshold storage unit 158 in association with a storage-destination queue of the packet. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
