Optimal routing for networked control systems using OpenFlow

Abstract

Networked Control System (NCS), which implements a feedback control loop over a communication network connecting sensors, actuators and controller, has gained a significance demand. However, in many cases, the infrastructure is not previously designed for dedicated control network because of the cost or because of the technology vision. Therefore, NCS should utilize the popular IP networks, which often do not provide any QoS provision. This is a challenge as NCS are sensitive toward delay and loss. In this thesis, I want to revisit a previous study on NCS, as well as to look at the measurement of delay in previous literature and current market devices. After that, I will point out the challenges of implementing NCS services of the previous study in real switches supporting SDN technology. Finally, I propose a solution on the most popular platform of SDN technology and demonstrate my evaluation.
