    • published v9 last week
    • minor correctiosn
    • discussion if we should submit to IESG
    • XAVI: maybe wait to the plugtest outcome as it will help to detect little nits on the examples and other details from 15.4e
    • PASCAL: recommends to push the button and then with the comments and during the review include the changes derived from plugtest
    • THOMAS: we want to avoid having to republish RFC in case a bit is wrong.
    • PASCAL: asks Pat Kinney to move the minimal document through the 15.4e interest group so we get feedback from it

    • PAT agrees.

  • [07.??] ML updates

    • 6top get remote routing information

    • 6top will be augmented with minimal and generic routing information

    • ROLL will develop a more sophisticated model later.

    • TX power control from the YANG model

    • overall tx power setting to a node


    • PAT: likes the concept. But in 15.4 is not defined as a controllable attribute. 15.4 does not have any way to set the TX power in a standardized way.

    • TW: would we break the std if we add this?

    • PAT: no but you will be out of specs

    Proposes to circulate the requirement to the 15.4 WG so it gets in when the amendments are released.

    • two ways to do this. e.g indicate the power and indicate that power is too low or too high so reduce it.

    • ACTION: to ask Anan to contact Pat to ask to consider the proposed requirement.

    DIscussion in the ML about IE termination fields.

    • PAT: sent an email indicating a document with an IE table guide. There is an explanation on how to use the IE and the termination IEs.


  • [07.38] progress on draft-ietf-6tisch-6top-interface

    • dedicated call on Monday
    • discussed interface draft. What we miss and what we should do to get to the next version published before cutoff date
    • three issues:
      • how to version
      • if we want to change the interface how to version it. security
      • security is beyond the 6top interface scope. We consider to keep 6top simple and provide the minimal security capabilities to setup the minimal draft K2.
    • next steps
      • remove commands sections and editorial changes.
    • open questions:
      • need to discuss how to specify if attributes are read or write
      • more consistent naming
      • setting multiple resources with a single request.
    • With COMI we still need to contact multiple times the resource if more than 1 property needs to be set.
  • Next Call 3rd July

  • IETF final agenda published then
  • Draft cutoff date 6th?

  • [08.48] AOB *No other B.
