Abstract

Methods of operating a communication node are provided. A method of operating a communication node may include receiving data from an electric grid device via a network interface. The method may include processing the data from the electric grid device at the communication node. Moreover, the method may include transmitting a filtered portion of the data to an electric utility head end system, after processing the data at the communication node. In some embodiments, a method of operating a communication node may include using a message broker controlled by a virtual machine in the communication node to provide a protocol to interface with a field message bus that includes a standards-based or open-source Application Programming Interface (API). Related communication nodes and computer program products are also described.
