Hello, I have been selected as the Routing Directorate reviewer for this draft. Document: draft-ietf-teas-applicability-actn-slicing Reviewer: Tony Przygienda Intended Status: Informational *Summary:* In short, the draft has been a pleasure to read. It is well structured, informative and carefully laid out presenting actually a good overview of the whole network slicing & service modelling jungle of drafts so overall, time well spent for me ;-) *Comments:* Only thing to remark is that the draft references a lot in-flight drafts in section 4 and given that, after publication the ground may move and it may lose relevance to an extent. I do not consider that likely. *Major Issues:* *None* *Minor Issues:None* *Nits:* Polished, easy on the eye language, nothing sprung out.
