Output scheduling method of crosspoint buffered switch

Abstract

Provided is a method of scheduling an output in a crosspoint buffered switch by searching whether a cell exists in a crosspoint buffer at a start position for each output port, wherein the crosspoint buffer at the start position is a crosspoint buffer at a predetermined position among the crosspoint buffers respectively corresponding to output ports, outputting all cells stored in the crosspoint buffer at the start position and searching for a cell in a crosspoint buffer at a next position, outputting all cells stored in the crosspoint buffer at the next position and searching for a cell in the crosspoint buffer in a next position to the crosspoint buffer at the final position, and outputting all cells stored in the crosspoint buffer at the final position and searching for a cell in the crosspoint buffer at the start position.
