Latency Measurement in an SDN Network Using a POX Controller

The use of Software-Defined Networking (SDN) offers several advantages, including flexibility, and a dynamic way of programming functionality in a network. The design and capabilities of the underlying SDN infrastructure influence the performance of common network tasks, therefore, it is important to know how to measure different performance parameters in an SDN network. In this study, we analyze the traffic that is traveling across an SDN network, and from that analysis we infer its latency using a POX controller. Furthermore, we validate the statistical relevance of measurements by analyzing their mean and standard deviations.
