ABSTRACT:
A network switching device is provided for enabling priority control of packets, enhancing the using efficiency of a buffer for storing a received packet, and reducing the costs of components. The received packet is stored in the corresponding buffer with information of the packet under the control of a buffer controller. Further, a priority determining circuit is also provided for determining a priority class and a destination of the received packet. The buffer controller creates a transmit queue to which the packets of priority classes are to be registered in each buffer. When writing the received packet in the buffer, the buffer controller is served to reserve the received packet for transmission next to the last registered one of the packets of the same priority class registered in the corresponding transmit queue based on the determination of the priority determining circuit.
