Abstract

PURPOSE: To reduce a cell rejection rate by deciding the connected condition of its own switch based on a destination address and an idle or blocked state identifying bit stored in the header of a cell by means of each 2×2 unit switch.
CONSTITUTION: An idle or blocked state identifying bit I to indicate whether effective information is stored in an information field D of the cell or not is provided to a heater H of the cell, and each 2×2 unit switch 18 the connected condition of its own switch 18 based on a destination address AD and the identifying bit I stored in the header H of the cell. Consequently, when the cells having the effective information collide with each other, the cell with a high priority is outputted to a prescribed output terminal according to the stored destination address AD, the cell with a low priority is rewritten in a condition in which the identifying bit I stored in the header H does not have the effective information, and it is sent to the terminal at a side different from the prescribed output terminal. Thus, the rejection rate of the cell is lowered.
