Active Measurement Approach to Traffic QoS Sensing for Smart Network Access in SDN

Abstract

Power communication network is very important for management of the power system. We propose a SDN-Based active measurement method to measure the evaluation parameters of the smart network access in the power communication network. Firstly, we introduce the some instructions provided by the OpenFlow protocols. Secondly, we define the parameters that should be measured in the power communication network to evaluate the performance of the network, and give the corresponding measurement method with them. Next, we proposed a SDN-based active measurement algorithm that updates its measurement interval based on the measurement throughput changes. Finally, we use the Mininet simulator and the POX controller build a simulation platform, and the simulation results show the accuracy of our proposed method and the measurement load of our proposed method are both better than that of Polling measurement methods.
