摘　　要：系统分析了现有AQM算法对于链路拥塞程度的判断机制,为解决算法对动态数据流响应速度慢,以及链路利用率较低的问题,提出了基于路由队列和负载因子相结合的AQM算法QLFC,并采用瞬时队长对丢包概率函数的进行自适应调整。实验证明,改进算法提高了对负载变化的响应能力,增强了主动队列管理算法的适应性和鲁棒性。We have studied the mechanism of existing AQM algorithms to judge the status of link congestion.An new approach based on queue length and load factor is proposed to improve the response speed and link utilization rate when dynamic data flows emerge.The active dropping probability is modified self-adaptively with instantaneous queue length.The experiments show that improved algorithm can achieve fast response speed under changeable load factor and it raises the adaptability and robustness of algorithm.
