Abstract:

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.
