针对主动队列管理算法普遍存在的公平性问题,提出基于速率的公平队列管理算法RFED。该算法根据分组的到达速率调节丢包率,将队列的到达速率控制在链路的服务速率下,根据非响应流UDP数据包空间分布特点,对非响应流实施有效的惩罚,以保证不同数据流之间的公平。NS仿真实验表明,该算法在公平性、稳定性等方面效果良好,无需进行复杂的参数配置,容易在现有网络中实施。
Aiming at the problem of fairness existing in active queue management algorithms, a fair rate queue management algorithm (RFED) is proposed. The algorithm adjusts the packet loss rate according to the packet arrival rate and controls the queue arrival rate at the service rate of the link. According to the spatial distribution of non-response UDP packets, the algorithm effectively punishes the non-response flow so as to ensure different data Fair between the streams. The simulation results of NS show that the algorithm works well in the aspect of fairness and stability without complicated parameter configuration and is easy to implement in existing networks.
