Hello Carles, Shwetha, authors, all,
I've read draft-ietf-6lo-minimal-fragment-01.
It seems clear and well written.
I only have a few comments:
Section 1, Overview:
"Each fragment can be uniquely identified by the source and destination
link-layer addresses of the frame that carries it, and the datagram_tag."
It seems to me that "datagram_offset" should also be mentioned here as
contributing to uniquely identifying a fragment.
Section 2.2
"Assuming the topology from Figure 2, where nodes A, B, C and D all send
packets through node E." Incorrect grammatical construct.
Section 3
"Each VRB table entry can be 12 B (assuming 16-bit link-layer addresses)."
It is not immediately obvious to me why 12. I guess I could try to figure
it out.
But [ARTICLE] says 20. Probably under a different assumption.
Could you provide a detailed count, to spare the reader the exercise?
BTW, in [ARTICLE], it seems to me that some means and remembering which
fragment have already been forwarded are missing. The key sentence is
"After having forwarded the last fragment, node B clears that VRB entry",
but how does node B knows is has forwarded all fragments? The same comment
applies to draft-ietf-lwig-6lowpan-virtual-reassembly-01. But I'm
digressing here.
Section 7, references
Ref [ARTICLE] is dated 2009, I guess you mean 2019. Besides, I could only
find the HAL archive, I suppose this is accepted for publication, but not
published yet.
Oops, just saw that Georgios already uncovered this nit.
Best regards
Dominique
