Hi Matthew and Stewart,
thank you for your work addressing my comments; much appreciated. I have
several follow-up questions and comments to the new version of the draft,
mostly to the new Section 3.1.2
<https://datatracker.ietf.org/doc/html/draft-bocci-mpls-miad-adi-requirements#section-3.1.2>
:
- I may suggest an editorial update to bullet 2
OLD TEXT:
2. A common mechanism for ancillary data MUST be defined so that a
node receiving the ancillary data can determine whether to
process, ignore or discard it.
NEW TEXT:
2. A common mechanism for ancillary data MUST be defined so that a
node receiving the ancillary data can act according to the local
policies.
- bullet 4 receives two notes:
- I think it should be a requirement, not a recommendation
- I think that an LSR must not be able to insert any ancillary data.
Only ingress LER inserts data.
- it would be good if bullet 6 can be split into two
- RE: bullet 7, I don't think that MPLS is the appropriate layer to
guarantee in-order delivery. Should that be left to an application?
- it appears that bullet 8 is specific to the PSD case. If that is the
case, should it refer to the BoS instead of "as close to the label stack as
possible"?
- I think that having a requirement for the use of a common ancillary
data header will help the discussion.
Couple nits:
- "an/or" -> "and/or"
- s/lath/path/
Regards,
Greg
