Abstract
When a plurality of pre-stage packet controllers receive an instruction on transmission of the priority information from a post-stage packet controller, they derive priority information on the basis of the ratios of bandwidths which can be used at minimum by the user devices, and statuses of storing packets in the buffers, and transmit the priority information to the post-stage packet controller. The post-stage packet controller then selects a pre-stage packet controller to be actually given packet transmission permission on the basis of the priority information received from the plurality of pre-stage packet controllers, and transmits an instruction on packet transmission permission to the selected pre-stage packet controller. The pre-stage packet controller which has received the instruction on packet transmission permission from the post-stage packet controller then transmits a packet to the post-stage packet controller.
