I agree with Noriyuki-san, especially about 15.4e. There are some nice
features in 4e in addition to the sleepy routers, such as reduced header
size, and flexible extensions to the header for things like mesh under.

Hi Geoff,
I have an interest in working on mesh under discussion and vote yes to start
discussion for it.
Some L2 protocol defines the mesh routing protocol in its L2 specification,
however some don't have (802.15.4 decided not having mesh routing in it, as
you mentioned in last meeting.) For the L2 which doesn't have mesh routing,
I believe we need to extend dispatcher for generic commands, carrier of mesh
routing metrics, L2 address basis source routing etc. as route over works on
ICMP. However, I'm afraid that I cannot write a draft up by the next IETF
meeting unfortunately.
Besides, IEEE802.15.4e is going to finalize its specification and it will be
done around end of this year. It has many optional MAC functionalities,
which includes low energy which enables sleeping router. I'm looking forward
to incorporate sleeping router functionality into 6lowpan.
We still have many items to do in 6lowpan WG.

Subject: [6lowpan] agenda for upcoming IETF
As you all should know the 6lowpan WG meeting is currently scheduled for
Tuesday afternoon 1520-1700 and we are looking for agenda items.
There has been little or no discussion on our mailing list since the
last IETF meeting.
Hopefully the ND and HC drafts are basically complete. The Use Case and
Routing Requirements drafts are moving forward.
At the last meeting the other topic that seemed to have some traction in
the WG was working on other header compression techniques. We have two
different drafts on this topic: Carsten's generic header compression and
Colin's ICMP header compression.
The other topic that hotly discussed atwas whether the group should work
on Mesh Under.
Again we have had no discussion on our list about any of these topics.
Besides the drafts from Carsten and Colin, we have had another draft on
global address compression.
The meta topic we need to discuss both at the meeting and on this list -
Should we call it quits or should we recharter?
Input???
