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.

Systems and methods for network traffic monitoring

This disclosure pertains to systems and methods to detect network errors in a parallel redundant protocol (PRP) network. A node-level redundancy error subsystem of an intelligent electronic device (IED) maintains records (e.g., counts) of information associated with missing duplicate frames expected from node devices on the PRP network via redundant first and second local area networks (LANs). Non-zero counts of missing duplicate frames may be identified as network errors.
