Agreed. Also for the relatively-long term solution, I doubt there is an one-size-fits-all solution. We need to have enough building blocks in protocols and any data center design/operation can utilize with to achieve their operational goal.

And hopefully some elements deployed in the short term can be leveraged and further tuned for the long term solution.

If we can list all the requirements and see what technical approaches we can do to achieve them. But incremental improvements on existing protocols is useful also. They may not solve the complete set of “requirements”, but they do help data center and also non-data center deployments to improve their operations. I would think this group can proceed with both approaches.

You can peruse the dcrouting mailing list archives. https://mailarchive.ietf.org/arch/browse/dcrouting/ It is rather befuddling to me that the IETF seems to have decided to move forward on two new protocols (no objection from me) but seems to feel there is insufficient reason to move forward on proposals to extend existing IGPs. I think the suggestion that we need to write (yet another) requirements document before doing so is a recipe for delay – not for progress. Multiple drafts have been presented over the course of the past two years and discussed on the list as well. In the case of two of the drafts: draft-shen-isis-spine-leaf-ext draft-li-dynamic-flooding WG adoption was requested in Montreal. Please explain why we cannot proceed with “business as usual” as regards these drafts.

Would help to disambiguate requirements from claims and have apple to apple comparison. Doing it on github was a good experience.

In fact, we have so many proposals that there wasn’t agree as how to move forward and we agreed to discuss on the list. This Email is to initiate that discussion (which I intend to participate in but as a WG member). Hi Acee, Perhaps a useful starting point of the discussion is to talk about requirements. There seem to many different perceptions.
