| 摘要: |
| 网络服务质量控制已经成为互联网技术的主要研究方向之一．主动式队列管理以及RED(randomearly detection)算法的改进问题是近期网络服务质量研究的一个热点问题．提出的基于平衡点的自适应RED算法可以根据网络上的流量特点，动态地修改最大丢弃概率，能够对不同类型的数据流聚集进行调节，与目前大多数其他RED改进算法相比，该算法没有采用逐步逼进的途径，而是基于计算的平衡点，修正最大丢弃概率，可以更快的达到稳定状态，从而解决RED算法对于参数的依赖性和队列抖动问题． |

| Abstract: |
| Quality of services is a key to next generation Internet．More people focus on these problems，such as active queue management and random early detection．In this paper,we present an algorithm of adaptive RED，which can modify the max probability of packets dropping．We modify this parameter based on calculating the equilibrium point，so we can get the steady-state faster than some other methods based on self-adjustment． |
| Key words: active queue management random early detection probability of packets dropping adaptive equilibrium point |
