Hi Pascal,

  I think the multicast-over-wifi discussion will be interesting for folks  in 6lo (regarding RFC6775) .

The goal is to reduce the  unnecessary signaling in the protocols and especially in efficient-nd (discussed in 6man) we had many rounds of discussions on wifi multicast behavior. 

Fixing 802.11 behavior for multicast will be helpful in many usecases to properly handle multicast messages.  However, I believe in general the protocols should reduce multicast signaling in  constrained node networks as well as in environments with virtual networks and VMs.

Hello Dan,

I'd see it useful to give this a lot of visibility and accessibility. A BoF-type meeting outside of meeting hours at this or the next IETF would probably improve that piece. INTAREA has collisions that people did not necessarily get a chance to manage in advance so interested people may miss the presentation.
I would like to be sure that most interested parties have a chance to know that this is happening at all.

Some of these discussion will relate to work happening at various WGs. Out of my hat and not copied above I see at least 6lo and MANET which deal with radios networks and need efficient network and service discovery. Cc ing 6lo because this is where RFC 6775 originated, and new work is taking place.

There will be serious discussions, and probably documents produced in the form of best practices. This work may deserve a short-termed WG on its own. A non-Wg forming BoF would help figure all that out.

Cheers,

Pascal
