Thanks Chairs/Pascal/Carles for getting fragmentation issue on the forefront!
My take on handling the issue would be: 1. Check what best can be achieved with single buffer policy 2. Check what improvements can be achieved if a standby (but pooled) buffer is allocated for managing fragmentation and put up signalling/routing changes .... may be fragment-forwarding can help here. 3. Make above two compatible with each other 4. Identify implications of changing the routing behaviour for fragments on intermediate 6LRs... Like Carsten said, the current routing has been there for long and that might have lead to some ossification! (May be this should be first on the agenda item) 5. Put up "realistic RF simulation and hardware testbed" for experimenting ... Cannot rely on Cooja for this. Regarding my interest/experience/deployment scenario, I had mentioned this on ML before in the same context ( https://www.ietf.org/mail-archive/web/6lo/current/msg02365.html). I can help with the design/review/experimentation.
