一种基于动态阈值的主动队列管理算法

A DT-Based Active Queue Management Algorithm

针对BLUE算法缺少早期拥塞检测机制,导致队列溢出或空闲现象频繁发生的问题,通过引进基于动态阈值算法的控制机制,借鉴RED算法所采用的早期拥塞检测机制,提出了DT-BLUE算法。仿真实验表明本文算法能保持队列长度的稳定性,有效降低队列空闲或溢出现象的发生,提高链路的利用率。

One improved method of active queue management algorithm was presented in this paper.Aiming the shortcoming of parameter setting in BLUE,the paper improved BLUE through introducing into dynamic threshold algorithm.The simulation results demonstrate that the proposed approach can effectively stabilize the queue occupation at a level and mitigate the queue overflow and underflow,and it can improve link utilization.
