Dear Greg, As you know, there are a number of proposals in the so called ‘Beyond SRv6’ topic. Unifier Identifier is one, but there are others. Given that we are not seeing some natural convergence on a solution, I think that the WG needs to refine the technical issue(s) that we want to address and the requirements for the new solution(s)/extension(s). Cf slide 9 of latest chair’s slides https://datatracker.ietf.org/meeting/106/materials/slides-106-spring-sessa-chairs-slides-01 more specifically > Several solutions on the table. Need to be explicit about the goals and the costs of each proposal. > ■ Authors are invited to explicit both in their document (short text) Then we can look at merits and costs of each solution, possibly refine them, possibly converge on a single one, probably drop multiples. This first step is to be done in the SPRING WG. I’m assuming that this part be the hardest part. Once SPRING has figured out what we want to do on this topic, I would expect the header format and processing be done in the 6MAN WG. (This may eventually depends on the outcome of this first step; in particular this is assuming that both spring & 6man want & need something new) In order to prepare this first step, do you think that for the next meeting, the document could be updated to spell out: a) The goals/requirements that this proposal wants to address. Aka, why do we need a fourth SR data plane. b) Which goals/requirements are addressed by this proposal, and what are the costs. I would encourage to carefully think about “a” as it would be good to avoid discovering, in 3 years from now, that we missed something (again) and that a new team asks for a N+1 SR dataplane. On a personal note, I’d be also interested in any feedback about the reasons why we missed those requirements/goals when SRv6 has been originally proposed, discussed and specified, in order to avoid repeating the same mistakes. Thank you, Regards, --Bruno From: Greg Mirsky [mailto:email@example.com] Sent: Monday, February 10, 2020 11:16 PM To: 6man WG; firstname.lastname@example.org Cc: email@example.com Subject: Where to continue work on the Unified Identifier? Dear Chairs of SPRING and 6man WGs, on behalf of the authors of the Unified Identifier in SRH draft, I'm asking for your consideration and suggestion. We're looking for your decision on which WG may, at the time, become the adopter of this work. One the one hand, as the draft proposes an update to SRH by allocating the new field, 6man WG seems as logical as it was the group that has led the work on SRH specification. On the other hand, a significant part of the draft is on using the Unified Identifier to realize the Segment Routing with SRH in an IPv6 network. Please let us know if you have any further questions or concerns. Thank you for your consideration.
