- overview
- WG meeting
- overview
- Milestones are presented. Next week we will have adopted 6top interface and CoAP draft.
- [Raghuram] Pouria and Raghuram went through the CoAP draft and are analysing/identifying what needs to be changed to be aligned to 6top draft. Changes are very minor.
Action item: Raghuram and Pouria to publish new version of the draft and call for adoption 2 weeks from now.
- [Thomas] we need a little time so everybody reads it and decides about its adoption.
- The YANG model is the generic description of payloads, the CoAP draft is an implementation of the YANG model,
- The draft is a method to integrate the yang model using CBOR payloads
- [Thomas] At CORE WG meeting a week ago, a mail was sent to point out various management methods using CoAP (COMAN). Nothing really new there but we have to check.
- [Raghuram] Yes, saw e-mail, will take a look.

- Next steps
- 6top interface
- verification of YANG model; requires YANG people to validate
- Interface verification: to make sure the interface is enough to handle management of 6TiSCH
- [Pascal] as for the sublayer draft, it is a good opportunity to interact with the IEEE group. Collaboration will be beneficial. Ability to have an IE reserved for IETF.
- OTF draft.
- Integration with 6top interface. Analysis and implementation are required.
- complex part is the interface to 6top
- Xavi proposes to have a list of OTF/6top mappings for the next call so we can identify missing functionalities.
Action item: Diego and OTF team to prepare a list of OTF/6top mappings for the next call so we can identify missing functionalities.
- define a security architecture draft
- Integrate 6LoWPAN ND and RPL
- As demonstrated in the plugfest with the integration of SmartMeshIP network from Dust Networks and a Cisco switch
- 6top interface
- plugfest
- ND in-efficiency in WiFi (Pascal)
- Pascal presents the use of ND integrated to the LLN backbone.
- Multicast on WiFi wastes resources
- Wake up hosts unnecessarily
- Packets are sent at the lowest speed
- 6man and v6ops address similar problems
- identifies the main points to be addressed on other working groups such as 6lo, 6man etc.
- AOB [1min]
