Abstract: Systems and methods may be used to assess network communications by generating one or more current communication parameters based on communications at an intelligent electronic device (IED) within an electric power delivery system. Network communications may be assessed by determining, at the IED, whether the communications fall within one or more thresholds for the current communication parameters.

Abstract: Systems and methods are disclosed to monitor real-time digital data for degradation. In one embodiment, an intelligent electronic device (“IED”) in an electric power system may include an interface to receive a stream of digital data, the stream of digital data comprising a plurality of data frames. A protective action subsystem may monitor the sampled digital data and implement a protective action based on the stream of sampled digital data. A digital data degradation detection subsystem may analyze a plurality of digital metrics associated with the plurality of data frames and make a determination regarding degradation of a communication channel based on whether the plurality of digital metrics fails at least one threshold. In response to the determination, the digital data degradation detection subsystem may implement a response to the determination that the plurality of digital metrics fails at least one threshold.

Abstract: The present disclosure relates to systems and methods to conduct a fuzzer test on a device under test and configured for use in an electric power system. In one embodiment, a system may include a configuration subsystem to receive a parameter of the device under test. A fuzzer subsystem in communication with the configuration subsystem may be configured to conduct a fuzzer test on the device under test. The fuzzer subsystem may include a fuzzer state machine to generate input data to deliver to the device under test, a packet buffer to store input data generated by the fuzzer state machine, and a packet regulator to deliver input data generated by the fuzzer state machine based the parameter. A physical interface in communication with the packet regulator may transmit input data to the device under test based on the parameter.

Abstract: The present disclosure relates to systems and methods for testing communication systems. In one embodiment, a communication device tester may include a traffic disciplining subsystem to generate a first stream of data packets satisfying a metric and may communicate the first stream of data packets to a test device in a first test scenario. A delay subsystem may generate a variable delay in a second stream of data packets and communicate the second stream of data packets to the test device in a second test scenario. A data corruption subsystem may corrupt a third stream of data packets and communicate the third stream of data packets to the test device in a third test scenario. A test subsystem may determine whether the test device satisfies at least one criterion of each of the first test scenario, the second test scenario, and the third test scenario.
