Hi Eric,

Agree, I also believe that the authors will improve these two parts.

When I read the introduction, I see that the requirements come from the overhead introduced of header, I assume that this is a problem of SRv6, and we also can learn it from the previous revision of this document.  If not from SRv6, it is better to specify the requirements.

Regarding the security part, the rules should be settled down, two many discussions of it, it seems that it is not clear right now. As a foundational building brick, security is really important. Jingrong’s input may help.

[Removing my internet area director hat for this post]

While I understand that the document will evolve, I cannot "throw my voice" yet for WG adoption because:
1) the justification for this I-D is a mere 9 lines in section 1 and there is requirement neither from other IETF WG nor from other SDOs;
2) the management and security considerations are really weak in the current draft [1].

Personally (and still no hat), I would prefer to see the above points fixed before adopting the document.



[1] I am sure that Ron Bonica and his co-authors will improve these sections.

Subject: Adoption Call for "The IPv6 Compact Routing Header (CRH)"

    This message starts a two-week 6MAN call on adopting:

     Title:          The IPv6 Compact Routing Header (CRH)
     Authors:        R. Bonica, Y. Kamite, T. Niwa, A. Alston, L. Jalil
     File Name:      draft-bonica-6man-comp-rtg-hdr-21
     Document date:  2020-05-14

    as a working group item. Substantive comments regarding adopting this document should be directed to the mailing list.  Editorial suggestions can be sent to the authors.

    Please note that this is an adoption call, it is not a w.g. last call for advancement, adoption means that it will become a w.g. draft.  As the working group document, the w.g. will decide how the document should change going forward.

    This adoption call will end on 29 May 2020.

    The chairs note there has been a lot of discussions on the list about this draft.   After discussing with our area directors, we think it is appropriate to start a working group adoption call.  The authors have been active in resolving issues raised on the list.

    Could those who are willing to work on this document, either as contributors, authors or reviewers please notify the list.   That gives us an indication of the energy level in the working group
    to work on this.

    Bob and Ole
