基于区分服务的队列调度算法研究
Research on Queue Scheduling Algorithm Based on DiffServ
摘要
Abstract
Weighted Round-Robin (WRR) and Deficit Weighted Round-Robin (DWRR) scheduling algorithm' s advantages and disadvantages in the architecture of DiffServ was discussed. And based on DWRR,a Deficit Weighed Round Robin plus (DWRR+) algorithm was presented in this paper. The algorithm dynamically set the maximum number of bytes for the current queue based on its length. The algorithm remedies the shortcoming of DWRR that can not meet the characteristics of delay under the premise of guaranteeing minimum bandwidths for different type of services. Extensive simulations were performed using NS-2. Simulation results demonstrate the validity of DWRR+, which can ensure the quality of service of different business to some extent.关键词
