| 摘 要： | 针对目前基于CICQ(combined input and crosspoint queuing)支持组播的调度策略在公平性和实时性能保障方面存在的不足，提出了一种简单、高效的支持组播公平服务的分层平滑轮询调度算法——mFGSR (multicast fair service and group smoothed round robin)。mFGSR依据组播业务流的权重进行分组和平滑调度，具有良好的可扩展性和公平性能，能够适应实时业务的性能需求。理论分析和仿真结果表明，该算法具有良好的时延、吞吐量和公平性能。

| Abstract: | To overcome the deficiencies in supporting fair and QoS scheduling,this paper proposed a fair and simple high-performance multicast scheduling algorithm for combined input-crosspoint-queued switches,which was called mFGSR.mFGSR grouped and scheduled flows according to the weight of flows.It had good fairness and could adapt to the need of real-time performance.Theorotical analysis and simulation results show that the mFGSR exhibits good delay,throughput and fairness performance. |
