Abstract
A packet transfer apparatus is configured to perform packet exchange processing for exchanging multiple continuous packets with low delay while maintaining fairness between communication flows of the same priority level. The packet transfer apparatus includes: a packet classification unit; queues that holds the classified packets for each classification; and a dequeue processing unit that extracts packets from the queues. The dequeue processing unit includes a scheduling unit that controls the packet extraction amount extracted from the queue for a specific communication flow based on information on the amount of data that is requested by the communication flow and is to be continuously transmitted in packets.
