Hi Pascal,
I agree with your points and thanks for the reference !

Hello Anand;
At ROLL, we are discussing how the PCE could compute routes and use RPL
signaling to install them
(https://tools.ietf.org/html/draft-thubert-roll-dao-projection).
This is independent of whether there is a TSCH network or not. If there is
none, we do not benefit from the cell reservation and the associated
deterministic properties, but we can still optimize the path based on
constraints from a centralized perspective, and we still need 6loRH for packets.
Actually, the 6TiSCH architecture suggests (unless we change that in the
future) that even for tracks, if the packet inside the track is an IP packet,
then there is an RPI HbH option indicates the flow.
Cheers,
Pascal

Hi Pascal,
I certainly support the adoption even with respect to the upcoming 6tisch WG
activities since bit savings are desirable in LLNs. Thanks a lot for the draft!
There could however be one view that, as we are predominantly moving
towards centralized routing and scheduling based architecture, managed
through PCE installed routes and tracks, the role of distributed routing may
somewhat be diminished. This is not imply RPL goes away as there are always
going to be scenarios to carry IP traffic. The counter argument for this line of
argument is that if the soft cells left at LLN's disposal are indeed going to
be at
premium, why not these be better utilized ? The draft is going to be extremely
useful. What do you say ?

I support the adoption,
This draft makes a difference in the size of data packets in a RPL LLN, which
translates impact positively the energy consumption, the delivery ratio and the
available payload size.

Subject: [6lo] Call for Adoption for draft-thubert-6lo-routing-dispatch
All,
This starts a 6lo Working Group adoption call for the following draft:
A Routing Header Dispatch for 6LoWPAN
https://datatracker.ietf.org/doc/draft-thubert-6lo-routing-dispatch/
This draft solves a problem for ROLL, namely that of compression of RPL
artifacts. It also appears to be extensible enough that it could be useful for
other
scenarios, especially after discussions at IETF 93 in Prague (context switch
approach) and confirmation at IETF 94 in Yokohama.
This document is intended as standards-track.
Please send your opinion ( Yes or No ) to the mailing list on adopting this
document as a 6lo WG document.
This call will end at 00:00 UTC on December 1, 2015.
Regards,
Chairs
