一种基于速率的BLUE改进方法

A Rate-Based Method to Enhance BLUE

连接数量的显著变化会使得BLUE队列管理机制的参数失效并导致队列在丢包和空队列之间波动 分析和实验表明BLUE对于动态网络环境的适应性仍然存在不足之处 为了解决这一问题 ,通过引进自适应思想提出了一种改进方法 其主要思想就是依据数据包的到达速率自适应地调整其标记概率 大量仿真实验表明所提出的方法能够明显增强BLUE在动态网络环境下的鲁棒性 和BLUE相比 。

A significant change in the number of connections can invalidate the parameter settings of BLUE and cause the queue backlog oscillation between loss and under utilization Analysis and experiments show that BLUE is not strong enough to adapt to dynamic network environment To solve this problem, an improved method is proposed though adopting the adaptive thought The main idea of it is to adjust adaptively the marking probability of BLUE according to the arriving rate of packets Extensive simulation experiments show that the proposed method can enhance the robustness of BLUE considerably under dynamic network environment Compared with BLUE, it can improve link utilization and decrease packet loss rate at the same time
