Abstract :
In this paper we study the influence of Weighted Round Robin (WRR) scheduling algorithm frame size to the performance of Crosspoint Queued (CQ) crossbar switch. In order to show that throughput and cell delay can be adjusted with appropriate WRR frame size, we analyzed switch for different values of frame size and under the unbalanced bursty traffic. We show that WRR scheduling algorithm achieve throughput similar to Output Queued switch when frame size is low. Also, with an increase of the frame size, the delay decreases.
