COMMENT:
----------------------------------------------------------------------

I support Benjamin's and Alissa's DISCUSS positions. I also agree with the
several people who commented that this should be informational. Otherwise, I
have some minor comments:

§3.2.1.2,
- first paragraph: Please expand "GigE"

- "In general, users are encouraged to use, instead of, "do this when you
get the packet," a combination of:" - Hard to parse.

§3.2.2.2: Please expand "PREOF" on first use. I realize readers can probably
construct it from the previous few sentences, but it's more reader-friendly not
to require them to do so.

§3.3.2: "Robust real-time systems require to reduce the number of possible
failures." - The sentence does not parse.  Are there missing words prior to
"to"?

§4.1.2:

- "Distinguishing the function of two DetNet data plane sub-layers, the
DetNet service sub-layer and the DetNet forwarding sub-layer, helps
to explore and evaluate various combinations of the data plane
solutions available, some are illustrated in Figure 4."

Hard to parse. Also, there is a comma splice.

- "There are many valid options to create a data plane solution for
DetNet traffic by selecting a technology approach for the DetNet
service sub-layer and also selecting a technology approach for the
DetNet forwarding sub-layer. There are a high number of valid
combinations."

Does this refer to implementation/deployment options, or protocol design
options? If the latter, are the choices still open?

§4.1.3: Please define or expand DetNet-UNI.

§4.2.1, first paragraph: Does L1 stand for Layer-1, etc? If so, please spell it
out.
