Abstract
In an ATM switching system, calls are equally distributed. The ATM switching system is arranged by a transmission path storing unit for storing therein a transmission path to which a first terminal is connected; a terminal storing unit for storing therein a plurality of second terminals which constitute a group and the representative of which group is predetermined; a communication time calculating unit for calculating communication time by subtracting a communication start time instant between the first terminal and the second terminals from a communication end time instant between the first terminal and the second terminal; a communication amount calculating unit for calculating a communication amount by multiplying the communication time calculated in the communication time calculating unit by a use bandwidth; and a communication amount accumulating unit for accumulating the communication amount calculated in the communication amount calculating unit with respect to each of the second terminals. In this ATM switching apparatus, such a second terminal the accumulated communication amount of which is the lowest among these second terminals is selected as a terminal for call receiv…
