SDN-based Resilience for Smart Grid Communications

With the recent advances in SDN-based technologies, there is a great interest from different communities to exploit SDN for their domain needs. One of such domains is Smart Grid where the underlying network is going through a massive upgrade to enable not only faster and reliable communications but also convenient control. To this end, SDN can be a viable option to provide resilience in Smart Grid SCADA and distribution networks. In this demo, we present such an opportunity by utilizing SDN for redundant communications. Specifically, we introduce multiple connection interfaces among distribution substations. In case of any failures of the wired connection, the backup connection that uses a wireless interface will be enabled by using an Open Daylight SDN controller. To be able to show this, we integrate a network simulator, namely, ns-3 with Mininet.
