Abstract
A packet relaying apparatus includes queues holding packet information, and queue control units controlling dequeueing. The dequeueing means transmission of packet information from a queue of a previous stage to a queue of a next stage. The packet relaying apparatus further includes a packet information control unit that, on receiving packet information to be dequeued at the time of dequeueing, returns discard information and data volume corresponding to the received packet information, a first bandwidth adjusting unit that, on determining that the received packet has been discarded, discards the packet information, maintains a usable bandwidth, and transfers the discard information and the data volume to the previous stage, and a second bandwidth adjusting unit that, on receiving the discard information and the data volume from the next stage, adds the data volume to the usable bandwidth and transfers the discard information and the data volume to a previous stage.
