Hi Jouni,

Thanks for preparing this. Some small comments below:

- Slide 6: I'd remove "native" in "PW-based native DetNet" to be
consistent with the terms used in the draft (alternatively, I'd use
"IPv6-based native DetNet" in slide 7for consistency with "PW-based
native DetNet in slide 6).

- Slides 11 and 12: use the same order for "Flow-ID" and "SeqNum" on
the slides (right hand side)

- Slide 11: though I have no concrete proposal, I think the S-label
could be better introduced (maybe with a figure, also introducing the
(DA-)T-PE and (DA-)S-PE node terminology).

- Slide 14: "already be seen" --> "already been seen"

Thanks,

Carlos
