ICN Adaptation to LoWPAN Networks (ICN LoWPAN)
draft-irtf-icnrg-icnlowpan-11

Note: This ballot was opened for revision 09 and is now closed.

Ballot question: "Is this draft ready for publication in the IRTF stream?"

Carsten Bormann Yes

This is a good basis for running experiments with ICN in constrained node network environments.
There are a few nits left, at least one of which needs to be addressed before moving this forward to the next process step.

The "C" flag is rather confusing for the reader (set to 0 for compression); could this be an "U" (uncompressed) flag?
Clearly, the erroneous Table 1 reflects the need for such a change.

RFC 8930 and related have been published; this puts the present specification on somewhat firmer ground.

(Dummy edit, to check if an email goes out this time.)

Section 3.2., paragraph 3:
>    The stateless header compression scheme makes use of compact bit
>    fields to indicate the presence of optional TLVs in the uncompressed
>    packet.  The order of set bits in the bit fields corresponds to the
>    order of each TLV in the packet. 

  Ordering by value (vie the bitfield) can lead to reordering of TLVs
  after compression/decompression - I assume that is OK?

Section 5.1., paragraph 0:
> 5.1.  TLV Encoding

  Any reason why an RFC6256 encoding wasn't chosen here instead of
  inventing a new scheme?

Section 7., paragraph 1:
>    This document adopts the compact time representation
>    [I-D.gundogan-icnrg-ccnx-timetlv] for relative time values. 

  Maybe this draft should then normatively depend on the specification
  in [I-D.gundogan-icnrg-ccnx-timetlv] instead of duplicating it here?


Section 13.2., paragraph 2:
>    [I-D.gundogan-icnrg-ccnx-timetlv]

  Outdated reference: A later version (-01) exists of
