| 摘 要： | 该文提出一种基于控制平面背景流量测量方法的动态偏置时间算法。该算法以控制平面的探测突发丢失率为依据,估计瓶颈核心节点的背景流量,并据此动态设置偏置时间。理论分析和仿真表明:该算法能够在满足目标早到丢弃率的前提下,得到较适中的偏置时间,从而实现时延与早到丢弃率的较好折中。

| Abstract: | A dynamic offset time assignment algorithm based on the measurement of cross traffic on control plane is proposed.This algorithm uses probe burst’s drop ratio as observing variable to determine the core node,s background traffic and assigns offset time dynamically based on the measured result.Analysis and simulation show that this algorithm can get moderate offset time under target Insufficient Offset Time(IOT) drop ratio’s restriction and obtain tradeoff between end to end delay and IOT ratio. |
