Yes, I believe we made a lot of progress.  Most of us will be in Prague and having a meeting there to try and “wrap up” things will be good idea.

+ Alex
+ <te-topo-model> authors
Sue, Jeff,
The authors of the <te-topo-model> draft had a meeting today with one of the authors (Alex) of the <network-topo-model> draft and discussed ways to align the topo models. The consensus so far is that the <te-topo-model> WILL augment the <network-topo-model>. There are some issues that need to be worked out (mapping identifiers, termination-points), but those should get resolved in due course of time.

I'll sync up with you (Sue) and coordinate a meeting between the authors of the <te-topo-model> and the authors of the I2RS topo model(s) at the IETF --- hopefully early in the week.
Regards,
-Pavan

Lou and Jeffrey:

On 7/22, I talked with the TEAS TE authors team.  They had concerns about
how the I2RS was going to integrate the TEAS work.  I realized there are two
different approaches to the models - and I expressed my  hope that we could
have aligned/merged models.  I chatted with the I2RS topology draft authors,
and I found that the authors had not yet begun to work on the TE models.
The best plan is to try to get the TEAS authors and the I2RS Topology
authors together at IETF 93 and get a plan together for migrating these
teams together.

I will send a few times out to teams this evening.   It would really help
I2RS if the TEAS group would meet early in the week (or if the folks are at
the hack-athon like I am we may meet Saturday night).  We could then try to
give NETCONF our best insight on the TE additions.

 In order to prepare for this TE/Non-TE merge, I2RS WG need to finalize the
non-TE models in the topology.  Today's interim was target to firm up the
Service and T1 topology models, but the T1 topology model will not be ready
until IETF 93.  My message in June hoped that we would be to the TE models
by IETF so that NETCONF would have our entire scope, but we will not be
there by the beginning of IETF.   I2RS will be following up in August and
September with Interims that focus on the TE models in I2RS Topology model.

Do you have any other suggestions?

Sue

Sue, Jeff,
    Given some recent messages on the list, I thought it best to confirm
we're all still on the same page.

Based on our past discussions, it's my understanding that the work being
done in TEAS (see draft-ietf-teas-yang-te-topo) will serve as the foundation
for TE support in the I2RS models.  I complete agree that there are details
on how the different topology models will integrate/mesh still needs to be
worked out, and I assumed that this is what you/Sue were referring to above.
-- But we will not have two sets of TE topology models.

I believe that the authors of the respective drafts are already are working
this.  (Pavan, my co-chair as well as coauthor of the TEAS yang model, can
comment on this.)

Please let me know if I missed/miss-understood something.

Thanks,
Lou
(as TEAS WG co-chair)
