Dear NETCONF WG,

below is the NETCONF WG session summary and AIs after IETF #95.

=> This mail is at the same time to verify the discussion result and decisions from the IETF 95 NETCONF session.
=> If there is no strong objection we will implement as discussed.

The NETCONF session took place on Thursday, April 7, 2016, from 2-4pm in Buenos Aires, Argentina.

- We had approx. 65+ participants in the 2 hour NETCONF session,
- We reviewed the status of the WG,
- We had a discussion on chartered documents.

- Many thanks to the note takers: Lada Lhotka and Jason Sterne and
Jabber scribe: Mikael Abrahamsson

The session agenda is available at: https://www.ietf.org/proceedings/95/agenda/agenda-95-netconf
The minutes of the session are available at: https://www.ietf.org/proceedings/95/minutes/minutes-95-netconf

Following is a summary of the discussion and the decisions taken per show-hands.

- Status update of the three drafts, RESTCONF, YANG Patch and YANG library. RESTCONF has some minor updates, and the other two drafts are in AD queue. Once the RESTCONF draft update is available, the write-up will be provided to the AD and WG.

- NETCONF YANG Push. The discussion centered around how best to organize the contents of the draft and draft-voit-netconf-restconf-push. There was also some discussion around filtering capability and to see if it could be extended.
Show hands result is that many are in favor of separating transport into a separate draft.

- Server Configuration Model. Discussion centered around keychain model and the need to split it from the configuration draft. There was no objection to moving forward on a keychain mechanism for NETCONF instead of preparing a universal method.
AI: Kent will bring the discussion on splitting the keychain model from the configuration draft to the mailing list.

- Zero Touch draft. There was some questions around where does zero touch configuration stop, and where does NMS take over.
AI: Kent will propose text around what is envisioned to be part of zero touch configuration.
Kent is planning to have LC in one month and finish the work in 2016.

- 5277bis. Eric Voit positioned the proposed work to be extensions to 5277 keeping backward compatibility. Original authors of 5277 Sharon and Hector seem to be fine with the arrangement and will be included as co-authors. 5277bis will include existing content from 5277 and replace it as RFC. The topic is chartered and the chairs will ask for adoption in a few weeks.
Result of show hands is that many in the room are in favor of the proposed extensions to the notification model.

- I2rs co-chair Susan Hares gave an update on i2rs requirements for NETCONF. Most of the discussion happened in i2rs.

- RESTCONF YANG push discussion mostly focused around the subject of the organization of drafts (see NETCONF YANG push above). The proposed names for the drafts are netconf-push-transport, restconf-push-transport, and yang-push-model. There will be four drafts including 5277bis. Current charter covers both NC and RC Push.
Show hands result is that many are in favor of having four drafts. Adoption should happen within a few weeks.

Regards,
Mehmet & Mahesh
