Poster abstract: NMEMD: A novel method for efficiently measuring software-defined network delay

Currently, many QoS-sensitive software-defined network applications expect the network end-to-end delay to meet certain constraints. In this context, it is significant to measure and monitor network delay. The only way traditional measurement methods can improve their accuracy is by increasing the number of measurement times or frequencies. However, the measurement process itself considerably consumes network resource. To address this problem, a novel method for efficiently measuring software-defined network delay, called NMEMD, is proposed to automatically optimize the measurement frequency and cycle based on the software-defined network delay. Simulation results demonstrate the ability of the proposed method to improve measurement accuracy of network delay and reduce resource consumption.
