Abstract
A communication control device includes an RM cell receiving unit which receives an incoming RM cell from a source terminal via a forward transmission line. A point-to-multipoint RM cell transmitting unit overwrites, when a congestion at a downstream portion of an ATM-based network is detected, a congested-condition ER value and a congestion notification data to the incoming RM cell received by the RM cell receiving unit, and transmits a point-to-multipoint RM cell, having the congested-condition ER value and the congestion notification data, to an upstream communication device via a backward transmission line, so that a state of the congestion is notified to the upstream communication device.
