[16:28] Architecture Next Steps [10 min]

• Presenter: Chairs, Ana Minaburo
• Associated draft: draft-ietf-lpwan-architecture
• Topics: Ivan’s comments, cont.
• let's have one architecture that encompasses all use cases.
• having the historical two steps of the architecture (point-to-point
  and multi-hop) does not help.
• Alex: once we have the new charter, we'll read the arch doc again
  and make sure everything is covered.
• Pascal: arch doc should describe how SCHC can be inserted between
  layers at multiple positions
• Pascal: discussion by Laurent on access control will get in there
  when stable enough.
• Laurent: access control just a draft, then find its way into the
  architecture. Should not be specific to point-to-point or mesh.
  E.g., make sure to identify SCHC instances.
• Pascal: please post a mail with crafted wording for the arch doc
  (security consideration section?)
• Laurent: not fully clear yet.
• Pascal: the "how" is in the standards track doc, arch is only
  overview
• Alex: we need time to work on the access control, looking forward to
  the discussion.
• Pascal: more discussion when Bob M is with us.
