A Distributed Scheduling Algorithm in Central-Stage Buffered Multi-stage Switching Fabrics
The current MSM switching fabric has poor performance under unbalanced traffic. To eliminate the internal congestion of switching fabric, we put forward a new central-stage buffered multi-stage switching fabric- CB3Clos and the backpressure-based strategy to control flows under credit-dispensed mode. By analyzing the condition to satisfy the central-stage load balance, we also advance an iSLIP alike scheduling algorithm-RGA. The simulation results show: compared with CRRD algorithm based on MSM switching fabric, the RGA algorithm has high throughput irrespective with the arriving traffic model and better performance in packet delay. At the same time, the QoS can be guaranteed.
