6lo

Summary

The 6lo working group meeting covered several topics including updates on existing drafts, applicability of IPv6 over short range optical wireless communication, and a proposal for a generic address assignment option. Discussions focused on clarifying protocol stack usage, addressing duplicate address detection, and determining the best path forward for address assignment options.

Key Discussion Points

IPv6 and Prefix Registration: Discussion on the draft that allows a host to claim a prefix to the router, and the desire for a mechanism for the host to prove ownership of the prefix.
Transmission of SCHC Compressed Packets over 802.15.4 Networks: Clarification of protocol stack options, the use of single-hop communication, and modifications to routing approaches (straightforward, tunneled, pointer-based). The need for guidelines on when to use each of these solutions was discussed.
Path Aware Semantic Addressing for LLNs: Updates to the base document were presented. Concerns about multicast and privacy were addressed. Need to address duplicate address detection in the document.
Generic Address Assignment Option for 6LoWPAN: Discussed the addition of a generic address assignment option and explored the idea of making Pasa a use case of a more general mechanism.
Transmission of IPv6 Packets over Short Range Optical Wireless Communication: Discussed addressing, neighbor discovery, header compression and fragmentation, and multicast. A question was raised about whether the protocol works if the link layer is unidirectional.

Decisions and Action Items

IPv6 and Prefix Registration: Pascal will update the draft with the new flow and the working group will provide feedback.
Transmission of SCHC Compressed Packets over 802.15.4 Networks: Align the draft with the chic working group architecture draft. Provide details on rule ID management. Complete examples in appendix a.
Path Aware Semantic Addressing for LLNs: The working group will review the updated draft. The document should clearly state that address duplicates are not possible.
Generic Address Assignment Option for 6LoWPAN: Decide whether to move forward with the generic address assignment option (GAO) as a separate document or merge it with Pasa. If GAO moves forward, revise the document. If not, wrap up Pasa.

Next Steps

Authors to incorporate feedback received during the meeting into draft revisions.
Working group members to review updated drafts and provide feedback on the mailing list.
Decision on GAO will determine the path forward for Pasa.
