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.
