The Optimization of the WRR Algorithm in Multi-Class Real-Time Data Scheduling
Shenghui Zhang · Computer Engineering and Science · 2012
With the development of converged networks,the quality of service(including the available bandwidth,end to end delay,jitter and packet loss rate)for some real-time data streaming applications(voice flow,video flow,etc.)become more and more important.The traditional WRR algorithm can only meet the fairness of the real-time queue,but it can not assure that the multi-class real-time data is low latency and low jitter.The BSTLRR algorithm is based on the WRR scheduling algorithm.The BSTLRR scheduling algorithm not only in the low delay and low jitter multi-class real-time data stream frame is superior to the WRR scheduling algorithm,and to some extent,the priority queue ensures the fairness of scheduling.
