摘要： A packet relay device is equipped with a buffer memory including a plurality of queues for temporarily storing packets, and a storage unit for storing the first queue lengths indicating the respective queue length of each of the queues and a second queue length indicating a value according to a total of the plurality of first queue lengths. When the packet relay device receives packets, it discerns the queue to which the received packet belongs from among the plurality of queues, and temporarily stores the packet in relation to the discerned queue within the buffer memory. Then, the first queue length and the second queue length are updated, and a determination is made of whether or not to send a congestion notification to the packet sending source according to the first queue length corresponding to the discerned queue, and to the second queue length.
