Communication networks and systems for power utility automation - Part 90-13: Deterministic networking technologies

IEC TR 61850-90-13:2021(E), which is a Technical Report, provides information, use cases, and guidance on whether and how to use deterministic networking technologies. Furthermore, this document comprises technology descriptions, provides guidance how to achieve compatibility and interoperability with existing technologies, and lays out migration paths. It will separate the problem statement from the possible solutions.
