摘要
在核心无状态公平队列调度(CSFQ)算法的基础上,针对其实际实现公平性方面的不足,提出了一种改进的MCSFQ算法。在链路产生拥塞的时候,根据队列长度的变化情况,对公平共享速率进行不同程度的调整,以使得公平共享速率的取值更加合理。仿真实验证明,该算法在保持了CSFQ算法的优点基础上,更进一步地改善了在不同数据流间带宽分配的公平性。
An improved algorithm based CSFQ (Core-Stateless Fair Queuing) to achieve the approximate fairness is presented. According tO the variety of queue' s length, the link fair share rate to take its value more reasonable as congestion is adjusted. Simulation results show that the new algorithm achieves comparable or even better bandwidth fairness between different data flows.
