Hi 6lo WG and all,I support the adoption. As a graduate student of Beijing
University of Posts and Telecommunications, which has been paying continuous
attention to the research and development of 6lo, I have my own understanding
after reading this draft.In the current architecture of network, the limitation
of address length, the over centralized design of networking and the high
overhead of routing protocol itself hinder the construction of large-scale LLN.
It’s glad to see alternative method is adopted to dynamically build the
network, which not only breaks the limitations of IP address, but also
eliminates certain routing overhead. It will make the system designers pay less
energy to the addressing and routing part. Considering LLN’s characteristics in
practical applications, it may need to consider more. I don’t know whether are
they belongs to L2 or L3 scope. But it worth my continuous attention to the
progress of this draft. And I am interested in building a demo to verify extra
considerations. The adoption and consensus to the solution would be
helpful.Regards,Zhen

for WG adoption of draft-li-6lo-native-short-address-03Hi Pascal and all, As we
know, the discussion of whether routing in LLN networks should run at Layer 2
or Layer 3 (network layer) has become a very sensitive issue for a long time.
With the advent of multiple low-power link layer technologies, such as IEEE
802.15.4, Wi-Fi, and PLC, network layer routing is clearly required. However,
the separation of mesh-under and route-over processes induces suboptimal routes
and (L2 and L3) duplicated re-route overhead. This draft’s topological
addressing method can integrate address and route information into a single
place. It will help to run IP layer on various link layer technologies and
meanwhile avoid above duplicated re-route issues. Thanks Pascal for continuous
advices and comments. As author of this draft, I want to state support of this
adoption. Regards, Guangpeng Li From: 6lo <6lo-boun...@ietf.org> On Behalf

<carle...@entel.upc.edu>du>; 6lo <6lo@ietf.org>Subject: Re: [6lo] Call
for WG adoption of draft-li-6lo-native-short-address-03 Hello Carles I have
reviewed the work carefully. I believe that we can achieve short packets with
6lo and SCHC so that piece is not an essential progress. So 6lo as an INT
areaWg does not need it.The essential progress is meshing without routing. It’s
probably hard to justify it at the routing area though the authors could try.
My feeling is that the idea is interesting but has a very narrow applicability,
which is in essence the opposite of IP. The progress applies only to very
specific L2 networks. This tells me that it is really an L2 technology and
should be used for MAC not IP. Bottom line is that I do not believe that the
work belongs to the IETF. I do not support adoption at 6lo. Regards, Pascal Le

Hi WG, I support the adoption call. In my opinion, this can help enlarge
scope of IP network, considering it may consume less resource of constrained
nodes. BR, Jing Wang From: Carles Gomez
