WG Status

IETF 110: status

ToDos from last meeting are done Request meeting for next IETF is done, 1h

[16:15] SCHC over LoRaWAN [5min]

  • Olivier: Still working on Ben Kaduk's comments.

[16:20] LPWAN Architecture [25min]

  • Alexander: New draft, much asked for
  • From CoAP draft, how do things work together?
  • How do we reset parameters, install context, compute IID, etc...
  • A framework was needed as opposed to scattered information in multiple drafts
  • For now the draft has the lessons from the SCHC OSCORE specification
  • Q from Juan Carlos: are upper/lower case significant in the picture?
  • Laurent and Alex: No; inherited from differnet documents
  • Ana: Can be used to show different instances
  • Pascal: I suggest you homogeneize
  • Edgar: Been discusseing with product. You could have crypto before TLS, same principle to have a separation where you have encryption
  • Alexander: true, good case. Each instance can be managed by different entities with different sets of rules
  • Alexander discusses how the 2 rule managers can talk to one another
  • Pascal: Need to instantiate the architecture with classic use cases 1) preprovisionned field device and 2) SCHCoPPP(oE)
  • Juan Carlos: Need some clarification about how this doc compares to the arhictecture described in section 3 of RFC 8724. Perhaps it can be called "Extended SCHC Architecture" and put a reference to 8724 section 3, explaining what else is now being defined (security, rules management, etc.).
  • Alexander: needed dto clarify the title; this is early work to get feedback
  • JCZ: I believe so *

[16:45] CoAP over SCHC [5min]

  • Ana: will publish 17 with language correction and Benjamin Kaduk's review
