摘要： 实现带宽资源的分配对于QoS控制来说是非常重要的。常见的带宽分配算法如WFQ、DRR等分组调度算法存在着诸如计算复杂度高、需在路由器进行每流状态的管理等不足。该文在前人的基础上,提出了一种基于RED的带宽分配算法,避免了上述问题,从而提高了算法的可扩展性。

Abstract: Bandwidth allocation plays an important role in QoS control.General bandwidth allocation algorithms,such as WFQ and DRR,have the shortcomings of high complexity and requirement for the router to manage per-flow state.This paper proposes a RED-based bandwidth allocation algorithm,which overcomes the mentioned shortcomings.So the algorithm is more scalable.
