带宽共享和拥塞控制对于Internet的健壮性和公平性是很重要的研究课题.对交换设备中流量共享拥塞链路的带宽公平分配进行研究,提出一个优化交换设备带宽的设置算法:根据出端口接收速率自适应设置入端口带宽门限,对入端口的带宽进行动态重新分配,提高资源利用率.模拟实验表明,此算法有以下优点:1)高适应性;2)最大最小公平性;3)快速响应网络变化;4)高可靠性;5)稳定性.
Bandwidth sharing and congestion control are very important research topics for the robustness and fairness of the Internet.This paper studies the bandwidth allocation of traffic-sharing congested links in switching equipment and proposes an algorithm to optimize the bandwidth setting of switching devices: The rate adaptively sets the in-port bandwidth threshold and dynamically re-allocates the in-port bandwidth to improve resource utilization. Simulation results show that this algorithm has the following advantages: 1) high adaptability, 2) maximum and minimum fairness, 3) fast Respond to network changes; 4) high reliability; 5) stability.
