DIME

  • DIME met on Friday morning with around 10 participants in the room.

  • Chairs solicit more activity to complete the end to end AVL level security milestone.
  • Chairs opened the discussion of potentially not having meetings in coming IETFs. The work could be done through emails and possible virtual interim meetings.

DNSOP

  • The Chairs were most pleased with the draft-woodworth-bulk-rr draft, as it was the authors first draft, and their first IETF, and was received positively.
  • There was also a short updates on the 6761 problem statements, and the current plan is to ask the working group to adopt one of the two drafts to move forward.

GROW

LMAP

Met on Friday 7/22. Main focus of the agenda was discussing open issues related to the three WG documents in WGLC. Good progress in solving the open issues due also to the f2f work done during the week by the editor and WG participants. Comments expected until 7/31, new version in August, followed by 2nd LC. Virtual interim in September if necessary. Proposals for new work are expected on the mail list. WG will meet in Seoul only if there is a consistent number of new proposals, or critical items that need to be solved f2f. The WG also received a presentation from the EC project and a demo of the Jacobs University implementation.

NETCONF

  • Approx. 120+ participants in the 2.5 hour NETCONF session.

  • Andy Bierman will provide an update for RESTCONF and YANG Patch within 2 weeks.
  • “YANG Push” drafts were discussed (Eric Voit, et.al.). The WG agreed to adopt the three drafts 5277bis, NETCONF Transport and RESTCONF & HTTP Transport. The next version of the drafts will be accepted as draft-ietf.
  • System Keychain Model, SSH/TLS Client Server Models, TLS/NETCONF Client Server Models, Zero Touch (Kent Watsen): Issues will be addressed and drafts will be updated as discussed. Client models will be addressed in the next version.
  • I2RS strawman proposal (S. Hares): Sue presented the I2RS requirements documented in ephemeral state draft. There was no further comments. The chairs asked the attendees to comment and discuss if they see an issue. Otherwise they will are seen as accepted. Sue agreed to provide an overview on which requirements are addressed in which draft and where an action is necessary.
  • Refined YANG datastores with Meta-data (R. Wilton): The datastore conceptual discussion is continuing in NETMOD WG. It has been proposed that the architectural discussion should be continued in NETMOD WG and the protocol part as well as the necessary changes to the datastore definition to NETCONF RFC should be done in NETCONF WG.

NETMOD

  • Two 2-hour NETMOD sessions (Monday and Tuesday)
  • Roughly 100 participants in both NETMOD sessions
  • The first session was dedicated to opstate and schema mount
  • The second session reviewed 9 chartered drafts and 3 unchartered drafts
  • Drafts nearing last call include 6087bis, routing-cfg, and acl-model
  • Ops AD stressed the urgency of unblocking other drafts ASAP
  • WG needs to provide clear guidance on how current drafts should handle 1) applied configuration and 2) derived state for system-generated objects in the interim while waiting for the rollout of a complete opstate solution

OPSEC

  • Three items on the on the agenda, all with an IPv6 orientation
  • WG is trying to progress -Operational Security Considerations for IPv6 Networks- after 4 years of existence to closure
  • WG meeting progressed positively and no notifications needed to highlight further to OPS ADs

RADEXT

  • Very high attendance by the standards of a radext meeting (19 people on blue sheets)
  • Productive discussions on all presented drafts

  • New Framework draft, replaces the former Architecture and Value Proposition drafts. The meeting supported its adoption as a WG draft (now announced on the SUPA list).
  • Problem Statement draft: vigorous discussion of whether it is needed, maybe it should be replaced by an Applicability draft. Further discussion was left for he SUPA list.

  • Reference model document presented work status. Progress since last IETF includes, etc. It is remaining for discussion how to handle the out-of-charter contents.

OPSAWG

  • draft-wu-opsawg-service-model-explained-01 explained the service model concept and service architecture.
  • A requirement of operator facing VPN model is proposed. While L3SM is customer facing, the composed VPN model helps operators to monitor, diagnos, and operat the PE based VPN deployment.
  • draft on IPFIX IE extension for BGP community. It's the first one based on basicList. It deserves special attention, review, and potential documentation as an RFC.
  • Automatic attachment goes a little further than the bootstrap process work.
  • In Band OAM was presented for comments from OPS.It's an interesting generalized "in band" method. We hummed to see if this work fit in OPS, some in favor none opposed.
