Performance analysis of crosspoint queued crossbar switch with weighted round robin scheduling algorithm under unbalanced bursty traffic

The possibility of enabling Quality of Service (QoS) in crosspoint-queued packet switches has been presented in this paper. For this purpose, the weighted round robin algorithm was simulated and analyzed. The packet delay represents one of the most important parameters in modern networks. Therefore,...

Summary:The possibility of enabling Quality of Service (QoS) in crosspoint-queued packet switches has been presented in this paper. For this purpose, the weighted round robin algorithm was simulated and analyzed. The packet delay represents one of the most important parameters in modern networks. Therefore, besides the throughput, we have been investigating the delay that crosspoint queued switch introduce, under bursty unbalanced traffic. Along with the average delay, the truncated maximum cell delay is analyzed. Results show that the weighted round robin scheduling algorithm achieves throughput similar to output-queued switch, under unbalanced bursty traffic, while maintaining low cell delay.
