  • IETF update [Chairs] [5min]
  • update security [Michael Richardson] [15min]
    • Doodle poll to stablish a new weekly meeting time for the security design team
    • Propose 45 min before 6TiSCH meeting
    • [Pascal] it would be good to have text to see what we want to achieve in the security design team
    • [Pascal] for example, discussions about PSK vs no PSK, certicates, etc. Define what is the approach we take and justify why others are not required.
  • plugtest: draft test description [Maria Rita, presented by Xavi] [15min]
    • [Xavi] Presents the plugtest; group of experts selected, includes Maroa-Rita, Xavi, tengfei and Thomas. Idea to develop the drafts on openWSN and make that a golden device with openMotes.
    • [Xavi] Days are 15 and 16 not 17. Includes the previsou pugtests plus new functions. There will be security, which was lacking on early minimal plugtest. We'll have tests for SF0 using 6top. SF0 will cover over provisoinning of bootstrap and runtime.
    • [Xavi] We'll also test 6LoRH and interduce test of backbone operation and registration of nodes
    • [Xavi] Plan is 21 tests. The final list should be available today (6/24) and publish the goldeen device by July 4th
    • [Thomas] Question about BBR. Test content OK?
    • [Xavi] describes the flows being tested
    • [Pascal] Yes, perfect
  • update 6top [Qin] [15min]

    • [Xavi]: ready to publish 01. Lists comments addressed on slide 24. Last change on concurrent trasactions that explains what happens when there are concurrent transactions. <text displayed on screen>
    • [Xavi]: do we want a method to resync a node that rebooted. One proposal is to have a message to get all the cells scheduled.
    • [Thomas] Question of complexity, and message size, maybe easier to simply reset all
    • [Xavi] Then we'd need to design a reset message at least
    • [Pascal] Let's continue this on the ML. Resetting will cause packet loss since there are no cells to carry the current traffic. Maybe we can represent the allocated cells in a concise fashion using a bitmap of sorts.
  • AOB [1min]

    • No issues raised.
