Hi Bala'zs, Thank you for the reply and clarifications. I still have a question on Q2. ... Q2: >> The first line of the 2nd paragraph of the Introduction says: >> >> “This document describes the concepts needed by any DetNet data plane specification…” >> >> What is meant by DetNet data plane specification? The definition of DetNet flows over a specific network technology? Please clarify, or reference if already defined elsewhere. > > <BV> Data plane documents focuses how DetNet packets are recognized and served according to DetNet service and forwarding sub-layer functions. >The next sentence is intended to clarify that. The next sentence is fine. It is just a little unclear to me what the definition of DetNet data plane specification actually is. Is it a specification that defines the combination of service sub-layer using protocol X and forwarding sub-layer using protocol Y?
