Abstract
A cell transmitted from a transmitting terminal is multicast to a plurality of receiving terminals. The plurality of receiving terminals respectively transmit B-RM cells to the transmitting terminal. Each of the B-RM cells is assigned an ER value. An ER value calculating unit calculates an average value of the ER values which are respectively assigned to the B-RM cells from the plurality of receiving terminals. A B-RM cell processing unit transfers to the transmitting terminal a B-RM cell to which the ER value calculated by the ER value calculating unit is assigned. The transmitting terminal controls the transmission rate of a multicast communication with the plurality of receiving terminals according to the ER value assigned to the received B-RM cell.
