摘要： 拥塞控制是网络设计中一个十分重要的问题。该文针对基于稳定性理论的拥塞控制算法SARED不能有效地增加带宽利用率的缺点,提出了增强型拥塞控制算法E-SARED。该算法可根据网络流量特性对队列占有率阈值 和最大输出输入带宽比两个重要参数进行动态调整,模拟结果表明,可有效地提高系统的吞吐量。

Abstract: Congestion control is a very important aspect of network design. Shock absorber random early detection (SARED) is a newly developed congestion control algorithm based on stability theory. This paper proposes an enhanced congestion control algorithm E-SARED aimed at the shortcoming of low bandwidth utilization of traditional SARED. E-SARED can adjust two important parameters: queue utilization rate threshold and the maximum of output input bandwidth ratio according to the network traffic characteristic. The simulation results show the efficiency of the improvement of system throughput.
