Dear Benoit, NETCONF WG,

below is a summary and action items from the NETCONF WG session on November 4, 2013 in Vancouver, Canada.
A short version of the summary is also available at: http://trac.tools.ietf.org/area/ops/trac/wiki/IETF88summary

- We had approx. 60 participants in the 2.5 hour NETCONF session,
- We reviewed the status of the WG,
- We went through the chartered WG items and had a discussion also on three non-chartered documents.
- Note takers were: Lada Lhotka and Balazs Lengyel. The Jabber scribe was Juergen Schoenwaelder.

The session agenda is available at: http://www.ietf.org/proceedings/88/agenda/agenda-88-netconf

NETCONF Over TLS update - RFC 5539bis<http://www.ietf.org/proceedings/88/slides/slides-88-netconf-0.pdf>
http://www.ietf.org/proceedings/88/slides/slides-88-netconf-0.pdf

We went through last changes and issues. The discussion on new port has been taken again. Opinion poll of the WG showed that many people were in favor of a new port and nobody against.
The WG also decided to separate the YANG module in a new document, align with the module in Reverse SSH draft and use it for both WG items.

Text on ZeroConfig has been put into ZeroTouch draft with some extensions.
There is an IPR on this draft. The chairs and the author informed the WG on the details.

The WG has still interest in the document to develop. There was not much comments on the maillist. Discussion on whether we need different solutions in one draft or the WG should select one. Also discussed whether the draft should be merged with DHCPv6 option draft. The discussion has been taken to the maillist.

RESTCONF Protocol<http://www.ietf.org/proceedings/88/slides/slides-88-netconf-3.pdf>
http://www.ietf.org/proceedings/88/slides/slides-88-netconf-3.pdf
Andy Bierman went through the last changes, the RESTCONF protocol summary and applicability.
The chair explained why it is proposed to develop in Netconf WG. The authors do not want to create a protocol which competes with Netconf. And it is seen as beneficial if Netconf and Restconf are developed in parallel and aligned with each other. There are obviously different projects outside of IETF (e.g. OpenDaylight) which use or plan to use Restconf. The opinion poll showed that there is a huge interest in this draft and nobody against. As a result of the discussion with the AD the WG chairs will prepare a charter update and adopt Restconf as the new WG item.

NETCONF Efficiency Extensions<http://www.ietf.org/proceedings/88/slides/slides-88-netconf-4.pdf>
http://www.ietf.org/proceedings/88/slides/slides-88-netconf-4.pdf
The draft proposes different extensions to Netconf, which have been partly discussed already earlier.
Approx. 15 hands in favor nobody against. There is more discussion necessary on the maillist. The WG participants are requested to provide comments on the extensions and highlight the importance for each of them.

NETCONF DHCPv6 Option<http://www.ietf.org/proceedings/88/slides/slides-88-netconf-5.pdf>
http://www.ietf.org/proceedings/88/slides/slides-88-netconf-5.pdf
Providing a bootstrapping option the draft has been supported. 10 hands in favor and 1 hand against.
The authors will discuss with the ZeroTouch author whether the two drafts can be merged.

OpenDaylight Update<http://www.ietf.org/proceedings/88/slides/slides-88-netconf-6.pptx>
http://www.ietf.org/proceedings/88/slides/slides-88-netconf-6.pptx
Jan Medwed presented on the OpenDaylight project status and how they use Netconf/Restconf and YANG.
The presentation also highlighted which extensions the project would like to propose Netconf and YANG.
OpenDaylight has a Restconf implementation and is interested to use such a RESTful solution.

Addendum:
After seeing that 6tisch WG discusses a draft, which plans to transport YANG modules with CoAP, Netconf chair proposed a discussion on Restconf. The 6tisch chairs found the idea good and the 6tisch, 6lo, Netconf chairs and the Restconf coauthors will meet on Thursday to discuss the use of Restconf in these WGs.

Cheers,
Mehmet
