* 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.
        * https://doodle.com/poll/y8vgcnxca5dychke
* 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.
