Abstract
A communication device, includes: a plurality of queues each configured to accumulate a packet; a scheduler configured to provide a permissible readout amount to each of the plurality of queues in accordance with an order that is based on a priority of each queue; a read processor configured to read out the packet from the plurality of queues, the permissible readout amount being consumed according to amount of the packets read out; and an accumulation amount counter configured to count an accumulation amount of the packets accumulated in each of the plurality of queues, wherein the accumulation amount counter notifies the scheduler of a change in the accumulation amount, and wherein the scheduler adjusts the priority of, among the plurality of queues, the queue of which the accumulation amount has changed, in response to the notification from the accumulation amount counter.
