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

["Jeffrey (Zhaohui) Zhang" <[e-mail]>]

I support the adoption.
Mark has said what I wanted to say. It's a simple, clean, useful and generic building block in IPv6, and ready to be worked on by the WG.

I support adoption.

The argument that this working group can't adopt CRH without a whole suite of supporting control plane protocols doesn't apply in my opinion.

This working group didn't define OSPFv3, IS-IS extensions for IPv6 or Multi-protocol BGP support for IPv6 itself either - they were developed in other working groups.

This working group defines the IPv6 protocol building blocks upon which others can use to build upon.

I am willing to commit time to working on CRH, as it solves a problem that has existed since RFC 1883 - the overhead of a source route with a set of 128 bit addresses.

It is not a new problem. What is relatively new (3-4 years or so) is the recognition of the significance of the overhead of using 128 bit addresses in a source route, due to SPRING's work.

6man need to solve this problem in a way that is consistent with both the architecture and design of IPv6, in a way that is compatible with the existing, very "brownfield" deployment of billions of IPv6 capable nodes.

Regards,
Mark.

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

 https://tools.ietf.org/html/draft-bonica-6man-comp-rtg-hdr<https://urldefense.com/v3/__https:/tools.ietf.org/html/draft-bonica-6man-comp-rtg-hdr__;!!NEt6yMaO-gk!XblpMb4jqsF-EHjM1SrhkgeZi4EvdQPastanzPbwlzprRPhYrL8LwSxEFHRbRx9m$>

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.

Regards,
Bob and Ole
