Re: [Teas] Poll on draft-lee-teas-actn-requirements-01 a WG documents

[Vishnu Pavan Beeram <[e-mail]>]

A few points to mull over and move the discussion along:

- Fitting "ACTN" into the "TEAS" body of work:
Work focusing on "how TE networks can be abstracted and managed in a
controller(s) driven environment" is an obvious item of interest to the WG.
And this is primarily where we believe the "ACTN" work can contribute; the
requirements discussed in the document that just got adopted by the WG
aligns well with this. The intent behind the name-change was to have
something generic enough to capture what we want this work to be about.
Note that this is just a requirements document and since this is the first
document to be adopted in this realm, it is important to get the "naming"
right now rather than later. "VN Controller" is perhaps not a great choice
-- very much open to other choices that would capture the essence of the
first statement above.

- Complementing existing TEAS work:
<draft-ietf-teas-interconnected-te-info-exchange> discusses the
architecture for the exchange of TE information between interconnected TE
networks in support of end-to-end TE path establishment. It discusses in
great detail the notion of "abstraction in TE networks". Our sincere hope
(belief rather) is that the <actn-requirements> document (and other <actn>
related documents that get adopted by the WG) would be complementary to
(/consistent with) the <interconnected-te-info-exchange> draft.

- Focus on the term "Controller":
One train of thought is to use this new work (conveniently facilitated by
the induction of ACTN into TEAS) to focus solely on the "controller"
aspects (given the belief that non-controller aspects are adequately
covered by existing solutions). Personally, I don't have a strong
preference on whether the "naming" should reflect this or not (Danielle's
latest suggestion - use "TE" in the ACTN acronym - is pretty close to what
I personally would like it to be), but it is important to get some clarity
on this "scoping" detail before zeroing in on any "name".
