Summary:A network communication system may include intelligent electronic devices (IEDs) in a dual-ring communication network. A software-defined network (SDN) device may be programmed by a removable or disconnectable SDN controller to control the flow path of data packets to the IEDs in the dual-ring network. A first ring of the dual-ring communication network may be dedicated to high priority data packets, and a second ring of the dual-ring communication network may be dedicated to low priority data packets. The SDN device may implement various levels of redundancy depending on the number and location of link failures detected. A first level of redundancy may direct high priority data packets in the opposite direction, and a second level of redundancy may direct high priority data packets onto the other ring normally used for low priority data packets.
