<p>PURPOSE:To prevent a cell from being abandoned at an input node in the large capacity exchange and to facilitate and accelerate exchange processing. CONSTITUTION:This exchange is provided with plural input parts and output parts, plural nodes 1-i (i=1, 2...128) provided with exchange processing control parts are connected through a loop-shaped highway 3, and the transmission capacity of this highway 3 is set larger than the total capacity of the input parts of these plural nodes. Since the plural nodes partially take the charge of exchange control, the exchange processing can be facilitated and accelerated, and decentralized control is performed. Further, since hardware scale is almost proportional to the square root of input capacity, the device can be economically constituted. On the other hand, the cell abandonment can be prevented.</p> |
