Hi Tim,

Many thanks for the review and the nits.
Updates will be done according to comments added inline.

Thanks

Reviewer: Tim Chown
Review result: Ready with Nits

Hi,

Re: INT-DIR review of draft-ietf-detnet-mpls-over-tsn-06

This draft details how a DetNet MPLS data plane can run over a TSN sub-network.

I have reviewed this document and believe it is Ready for publication, with Nits, as listed below.

Nits:

p.2
Loss rates -> loss rate
Provides congestion -> provide congestion For MPLS-based -> for an MPLS-based
<Bala'zs> OK.

p.3
Include MSRP and RSVP-TE?
<Bala'zs> OK.

p.4
And resources -> and resource
<Bala'zs> Already fixed in v06.

p.5
>From MPLS -> from the MPLS
Does not -> do not
In case of -> In the case of
<Bala'zs> OK.

As per the IP doc, not being familiar with DetNet in detail it might be useful to expand on the rationale for mapping to multicast given the “directed” flow.
<Bala'zs> OK. See IP doc reply.

p.7
As per the IP doc, I note it says there are no requirements stated for TSN-unaware MPLS DetNet nodes in the document, but is it worth adding something about requirements to ensure the TSN Relay can be reached?
<Bala'zs> OK. See IP doc reply.

p.8
Implementations -> implementation
<Bala'zs> OK. 

P.9
of the document -> of this document
challanges -> challenges
Are member -=> are members
Single hop -> a single hop
In some case -> in some cases
<Bala'zs> OK.

P.10
Regarding the more complicated triggering for TSN-unaware nodes, should further text be added about this?
<Bala'zs> I see your point, but that is more a control/management plane issue and not a data plane one.
Controller plane discussions recently started in DetNet, so I will keep this comment on the table. :--)))
