摘　　要：针对当前网络延迟测量相关研究成果在测量准确性等方面性能有待提升的问题,提出了基于边缘计算的物联网数据包传输延迟测量技术。基于测量网络边缘位置流量数据及边缘测量结果对物联网中各条链路流量数据进行评估。将数据包传输延迟部署规划划分成数据中心和内容分发网络以及边缘网络等尺度范围各异的测量体系,基于边缘流量估计,通过探测工具探测按一定顺序跳步的路由链路,依据路由器地址连接各路由路径,获取全局连通网络拓扑结构,根据物联网地址路由规则得到节点之间路由路径和相应数据包传输延迟。实验结果表明,该测量技术精度高,测量性能优于目前现有成果。The current research results of network delay measurement need to be improved in the measurement accuracy and other aspects. Therefore, the measurement technology of Internet of Things packet transmission delay based on edge computing is proposed. The traffic data of the edge position of the network is measured, and the traffic data of each link in the Internet of things is evaluated based on the edge measurement results. Divided into data center and the packet transmission delay deployment planning content delivery network and edge network scale of measurement system, based on the edge of the traffic estimates. By detecting tool further detection in a certain order hop routing link, on the basis of the router address connection by the path of all stripes, access to global connected network topology. Then the routing path between nodes and the corresponding packet transmission delay can be obtained according to the Internet of Things address routing rules. Experimental results show that the measurement technology has high precision and better performance than the current results.
