基于优先级分类的动态随机早期检测队列

Dynamic random early detection queue based on priority classification

针对随机早期检测(RED)算法在服务质量(QoS)保证方面的不足,提出了一种改进队列。该队列基于本地对数据分组的优先级划分,为不同的优先级类别设置不同的RED最大门限值。同时,此系列门限值根据各优先级分组的QoS参数测量值进行动态调整。实验表明,改进的队列继承了RED拥塞控制的优点,提供了一定的QoS保证功能。

To overcome limitations of Random Early Detection （RED） queue in Quality of Services（QoS） supporting,a improved RED queue is proposed.The queue sets different RED maximum threshold for different packet class based on local priority classification.At the same time,RED maximum thresholds are adjusted according to values of measured QoS parameters for each class.Simulation results show that the improved queue inherits advantages of RED and provides QoS in some degree.
