Hello Pascal,

While preparing my shepherd write-up for the 6lo fragment recovery draft, 
 I noticed one minor detail that I would like to bring to your attention.

In -05, draft-ietf-lwig-6lowpan-virtual-reassembly was added as a
reference. I think it is a bit odd that this document is mentioned for the
first time only at the end of the Security considerations section (note
that this reference is in fact a normative reference).

My proposal is updating the second paragraph of Section 1, and the last
paragraph of Section 2.4, so that
draft-ietf-lwig-6lowpan-virtual-reassembly is also introduced there.

For example, for Section 2.4, it could be something along the lines of:

CURRENT:
   "LLN Minimal Fragment Forwarding" [I-D.ietf-6lo-minimal-fragment]
   introduces the concept of a Virtual Reassembly Buffer (VRB) and an
   associated technique to forward fragments as they come, using the
   datagram_tag as a label in a fashion similar to MPLS.  This
   specification reuses that technique with slightly modified controls.

NEW:
   "LLN Minimal Fragment Forwarding" [I-D.ietf-6lo-minimal-fragment]
   introduces the concept of a Virtual Reassembly Buffer (VRB) and an
   associated technique to forward fragments as they come, using the
   datagram_tag as a label in a fashion similar to MPLS. The technique is
   described in [I-D.ietf-lwig-6lowpan-virtual-reassembly].  This
   specification reuses that technique with slightly modified controls.

... and something similar might work also for Section 1.

What do you think?

Thanks,

Carles (as the document shepherd)
