The FREEDM Architecture of Fault Tolerant Network Routing through Software Overlays

Control decisions of intelligent devices in critical infrastructure can have a significant impact on human life and the environment. Insuring that the appropriate data is available is crucial in making informed decisions. Such considerations are becoming increasingly important in today's cyber-physical systems that combine computational decision making on the cyber side with physical control on the device side. In the FREEDM system, power management of green energy is provided in a highly distributed and scalable manner. The system has to insure that Intelligent Energy Management (IEM) and Intelligent FaultManagement devices have the appropriate data to make control decisions for microgrids and with respect of microgrid connectivity to an upstream utility power grid.
