PACKET FORWARDING DEVICE AND PACKET FORWARDING METHOD, AND COMPUTER PROGRAM

摘要

Disclosed is a packet forwarding device which can keep down development costs and realize desired QoS control. Said packet forwarding device is provided with a second scheduler which includes: second packet queues corresponding to each of first packet queues of a first scheduler; a second packet classification unit (22) which distributes packet data to each of the second packet queues on the basis of a second classification different from the classification configured in the first scheduler; a throughput estimation unit (24) which estimates throughput, i.e., the amount of packet data forwarded from the first packet queues corresponding to the second packet queues to an information processing terminal; and a second packet scheduling unit (25) which forwards the packet data stored in each of said second packet queues on the basis of the throughput and the priority of each second packet queue.
