Collocated event between 6TiSCH and CoRe (OsCOAP). - Action: TW to contact Carsten - ETSI: Will organize providing TRT tool - Remark from Michael: Not having NDA in the plugtest. ETSI agreed to not have the NDA. - Maria Rita volunteers to be part of the organization team. - Remy asks for the test descriptions as a markdown document instead of workd or pdf file. - MR should use some online tools. - F-Interop tools will be used.
        - The test description will be published by mid of June. - 14th and 15th of July Plugtest. - for each test think how the assertions can be made true or false. - Remy agrees to be proof-reader of the test-description - MR: have a new set of tests that are already done from previous plugtests that can be ported to F-interop. No need to add everything. - Remy: to demo F-Interop in 2 week (next meeting). - Minimal, 6P, Minimal security?
        - Malisa: we are at a point were we can use minimal security with pre-shared keys. - MR: agrees. - Remy: are those minimal security frames supported by tshark (wireshark). - Malisa: there is no dissector for OSCOAP in Wireshark. - 6P -> Adapt from previous tests. - Call for experts: send CVs and selection process to write the test description. beta version for mid June. Final version for 1st of July.

  • [7: ] Update on security (Michael/Malisa) [10min]

    • Concern on using EDHOC and OSCOAP which are not being adopted by any WG.
    • We need a lower network cost mechanism (w.r.t. DTLS) and this 2 mechanisms fit our needs.
    • the 6TiSCH minimal security needs more explanatory tags indicating why is not covering some aspects. Comment from AD.
    • Malisa is working to provide an evaluation of the joining overhead considering different mechanisms.
    • The key of using OSCOAP is the lesser number of packet exchanges.
    • DTLS has 29 B of overhead.
  • [7: ] Research Liaison Task Force (Thomas) [ 3min]

    • It might be useful to have some tracking of what is going on in terms of performance, experimentation, evaluation, simulation, etc...
    • List the ideas of stuff that we would like somebody to work on and validate concepts.
    • How this was in the RPL days? Pascal.
      • Nothing formal in RPL.
      • Might make sense to have somebody looking at what is going on in the research/industry community and link it to our activities.
      • Use the IETF Wiki, listing the experiments , results, etc....
      • Xavi volunteers to move this forward.
  • [8: ] AOB?

    • No other B.
