To enhance the degree of freedom in adjusting or changing communication quality while realizing high-speed packet processing.
A packet input 1 stores an input packet into a packet buffer 2. A queue controlling unit 5 stores packet information into predetermined queues. A QoS (quality of service) processor 6 receives the packet information from the queues in the decided order in accordance with packet scheduling (priority control, weighting fair control or packet shaping), and notifies a below-described packet transmitter 7 together with a transmission request. The packet transmitter 7 acquires a storing address of a packet to be transmitted in the packet buffer 2 based on the notified packet information or a management number, and transmits the packet to be specified on the basis of the storing address in the packet buffer.
