PRED:一种配合队列调度的RED算法

PRED:an Active Queue Management for SPFQ

论文讨论了队列管理和队列调度的关系,提出了一种新的基于势的RED机制:PRED,以增强SPFQ调度机制的公平性,来达到整个报文处理系统的性能改善。通过严格的仿真验证,同其他的队列管理机制相比,PRED同SPFQ的结合能够最大限度地利用系统资源,提高服务的公平性。

This paper proposes an active queue management (AQM)called Potential-based RED(PRED)to enhance the fairness of SPFQ(Starting Potential Fair Queuing)in bandwidth allocation.By comparing it with other well known AQM algorithms ,we prove that the combination PRED-SPFQ for packet processing achieves ideal fairness in allocating band-width among even aggressive or unresponsive flows.
