Our WGs (6LoWPAN/ROLL/CoRE/LWIG) are about making IP work well on constrained node/network environments. A number of issues in this space are cross-layer (or at least cross-WG) in nature. While these are a constant topic in the hallways, maybe we can make more progress by getting a group of people in one room. We are going to have an informal get-together to discuss some of these issues at Thu, 1740-1940, room 102 While the room maybe is not optimal for an informal discussion (and the overlap with TLS is unfortunate for some of us), it does enable use of the projector -- and it was available now that the LISP WG meeting is canceled. I'm going to try to get some structure into the discussion. The following items have been mentioned as possible subjects (drafts are mentioned as potential background material): 0 -- implications of 802.15.4g, 802.15.4e on 6LoWPAN is there anything we need to do/should be doing to make 6LoWPAN more useful with these new/extended link layers in the 802.15.4 space? Anything beyond the adaptation layer? What about security/key management? Also: other links, e.g. 6LoWPAN for Bluetooth-Low-Energy draft-ietf-6lowpan-btle-03.txt (We had a nice lunch discussion in a small group today, so we are already mostly done with the basic work on this topic) e.g., what are the interactions of the Bluetooth security protocols/attribute protocol and the things we are doing on the IP side? 1 -- 6LoWPAN-GHC and its application to ROLL, SenML and other protocols draft-bormann-6lowpan-ghc-03.txt draft-goyal-6lowpan-rpl-compression-00.txt draft-goyal-roll-rpl-compression-00.txt draft-jennings-senml-07.txt Any other protocols that would benefit significantly from 6LoWPAN-GHC? 2 -- Cross-Layer implications of the CoRE discovery discussion Discover of servers, services, and resources sometimes interacts with discovery of network elements like proxies, routers, networks. http://tools.ietf.org/html/draft-brandt-coap-subnet-discovery-00 Is there a useful overlap between application layer discovery and network layer autoconfiguration? Related: 6LoWPAN vs. HOMENET What are the implications of the HOMENET architecture document and technical proposals on the typical deployment of 6LoWPANs for home automation applications? (Implications on discovery?) 3 -- LWIG draft-bormann-lwig-guidance-00.txt what can we do to discuss APIs in a meaningful way here? what else should be in this document? 4 -- extensions for industrial applications of 6LoWPAN draft-wang-6lowpan-scheduling-requirements-00.txt Are there solutions that could be implemented in 6LoWPAN that solve some of these requirements? Is it even useful to discuss industrial applications outside of the system standards ISA100.11a/Wireless-HART/WIA-PA (i.e., is there a "pure IPv6" space waiting to be explored)? 5 -- network management for constrained node/networks What is the best place to bring the various efforts together? Should we be doing the bigger picture in the IETF NMRG? This is a lot of items, and we won't cover all of them in these two hours, but maybe we can at least make interested people known to each other and spin off further hallway discussions. Maybe we can go through the items in this sequence (i.e., ≤ 10 minutes per number) in the first hour and then revisit points that merit more discussion. If you want to make a more structured contribution to, or lead, any one of these points, please tell me (and send a slide or two, if useful). Gruesse, Carsten PS.: To be redundantly clear, let me add this Disclaimer: This is not a BOF, not even a Bar-BOF. It is not about drumming up support for some potential work. Just about technical discussion. No intent to forcibly draw in ADs... PPS.: I have attempted to set a reply-to to 6lowpan. Feel free to answer to *one* of the WGs. Please don't spam all four.
