Abstract
ATM switch method comprises a step of accumulating a cell input from an input port in an input multiplex buffer connected to the input port to which the cell has been input; a step of inhibiting output of cell addressed to a certain output port from an input multiplex buffer when the cell of the certain output port equal to or more than a threshold value have been accumulated in the input multiplex buffer; a step of outputting cell except for the inhibited output cell from the input multiplex buffer and accumulating the output cell in an output buffer corresponding to an output port of the output cell; a step of outputting cell accumulated in the output buffer and accumulating the output cell in an output separation buffer corresponding to output port of the output cell; and a step of outputting cells accumulated in said output separation buffer to be output to an output port to which the cell is addressed.
