Reviewer: Ines Robles
Review result: Ready with Nits

I am the assigned Gen-ART reviewer for this draft. The General Area Review Team (Gen-ART) reviews all IETF documents being processed by the IESG for the IETF Chair.  Please treat these comments just like any other last call comments.

Document: draft-ietf-detnet-mpls-over-tsn-05
Reviewer: Ines Robles
Review Date: 2021-02-05
IETF LC End Date: 2021-02-05
IESG Telechat date: 2021-02-18

Summary:

This document specifies the Deterministic Networking MPLS data plane when operating over a TSN sub-network.

I have some minor questions to the authors.

Major issues: None

Minor issues: None

Nits/editorial comments:

- Page 5: Could you please describe what the "TSN treatment" comprise?

<Bala'zs> TSN treatment means to execute TSN functionalities during forwarding. I will extend the text
OLD TEXT:
       ... All these functions have to identify flows those 
       require TSN treatment.
NEW TEXT:
       ... All these functions have to identify flows those 
       require TSN treatment (i.e., applying TSN functions
       during forwarding).
END

- Are the security considerations the same for TSN-unaware that are for TSN-aware nodes? - How are the privacy considerations for those? It would be nice to mention explicitly how or where (I-D.ietf-detnet-security???) the privacy considerations are addressed for TSN-unaware and TSN-aware nodes

<Bala'zs> The I-D.ietf-detnet-security contains DetNet specific security considerations. TSN-unaware nodes are out-of-scope in the draft. TSN-aware nodes are part of both the MPLS and the TSN domain, where both domain has its own security considerations, which must be applied. 

Thank you for this document

Ines.
