ABSTRACT:
In a ring type ATM network system employing an ATM cell transmission mode, two paths are provided to correspond to a dual ring between node equipments, one path is selected to transmit a cell, and the other path is defined as a stand-by system. The path is selected for each combination of the node equipments, and is switched over to the stand-by system when a malfunction is caused. In order to configure a path for multicast, a multicast cell is not relayed between specific adjacent node equipments, thereby logically regarding the two rings as two buses. It is thereby possible to select a path having a smaller number of passing node equipments in a normal state, and reduce a transmission delay. During reconfiguration of a path at a time of occurrence of the malfunction in the ring or the node equipment, it is possible to reduce the transmission delay between optional node equipments to a delay less than a time required for one cycle of the ring, and to implement multicast transmission of the cell.
