摘要: 通过在数据包中附加路由信息, 利用路由跟踪的策略, 确定数据包到达目标节点所经过的路由器的数量, 以此给出网络诱导时延的在线估计方法, 从而较好地克服了利用时间戳方法测量网络传输时延时所产生的远程节点与本地节点之间的时间同步问题. 通过对引入的数据包路由信息的设置和网络路由瓶颈的分析, 给出数据包传输周期的下确界和一种简单的数据丢包的判别方法. 最后给出控制器的协同设计步骤, 实验研究验证了本文方法的有效性.Abstract: An online evaluation technology for network induced time delay by redesigning the application protocol without any additional apparatus is proposed in this paper. Firstly, a computational method for network-induced time delay online evaluation and a lower bound on the transmission period are achieved by using automatic route trace technology (ARTT). Secondly, a simple decision-making for the data packet dropout is also discussed. Finally, the controller co-design is described. The effectiveness of the proposed schemes is validated by experiments.
