Utility communications are increasingly required to support machine-to-machine communications for thousands to millions of end devices ranging from meters and PMUs to tiny sensors and electric vehicles. The Software Defined Network (SDN) concept provides inherent features to support in a scalable and self-configurable manner the deployment and management of existing and envisioned utility end devices and applications. Using the SDN technology, we can create dynamically adaptable virtual network slices to cost-effectively and securely meet the utility communication needs. The programmability of SDN allows the elastic, fast, and scalable deployment of present and future utility applications with varying requirements on security and time criticality. In this work, we design a SDN-enabled utility communication architecture to support scalable deployment of applications that leverage many utility end devices. The feasibility of the architecture over an SDN network is discussed.
