RE: [spring] CRH is back to the SPRING Use-Case - Re: Size of CR in CRH

["Ketan Talaulikar (ketant)" <[e-mail]>]

Hi Bob,



Perhaps I will try to make my case to you (and everyone else here) … one last time.



This is how I've seen RH work being done in 6man until now (in a matter that fits its charter).



1) There is a WG (not 6man) that defines the problem statement, use-cases and architecture that requires RH

2) The 6man being the experts on IPv6 design, either take up the document that specifies that RH (or even if it is done in another WG, reviews it).



So 6man has always had work done in (1) to reference and lean upon when doing (2).



My argument of the shortcut in the case of this specific adoption is that we don't have (1).



It is not in 6man charter nor expertise to take up (1) because CRH is not purely IPv6 work. It is not meant for "Internet" but a specific "limited domain". The SIDs that it introduces is a new "mapping ID" concept. It is not an IPv6 address and neither it is MPLS. This is a Routing Header and part of a new Source Routing solution.



Therefore, without (1) being made available to 6man, I believe that working on (2) in 6man is to me a shortcutting of the IETF technical review process (specifically of the Routing area in this case) for a solution and does not provide the necessary reference for 6man to work on.



Why the rush?



I close my arguments.



Thanks,

Ketan

But what I understand is that the reason why we have these "legal" process of charters and BoF is to enable a proper technical discussion with the right context and details of the proposal presented for review of the community.

There is no short cutting here.  The adoption call is to determine if there is interest in the w.g. to take this work into 6man.   If it becomes a w.g. draft, then the w.g. is responsible to decide what happens next.



It’s a first step, it is not a decision to publish it.



Bob (w/ w.g. chair hat on)
