We propose a new output arbitration method for an input buffered switch with a buffered crossbar. In the proposed method, each output selects the first nonempty buffer from the starting point. The starting points of output are determined to minimize the synchronization phenomenon that more than one input module sends cells destined for a same output. Using an approximate analysis of the synchronization phenomenon, we show the uniqueness of the starting points improves the switch performance. Finally, using computer simulations, we verify the proposed method outperforms the previous methods under the uniform and burst traffic.
