Thanks Carles,
Agree with your responses! Coming back to one point:
- Sections 3.2.2 and 3.2.3
In both cases, the second paragraph seems to repeat information
from the 1st paragraph but slightly different.
Is this intentional? If yes I can take a closer look to trying to
understand this. If not intended, then I'll await new text.
Yes, this is intentional!
This relates with SCHC architecture concepts, as follows. There is a
SCHC Stratum (atop 802.15.4 and below IPv6). There is only one SCHC
Stratum Header end point in either case. In the second case
(Multiple-end point networks), the SCHC Stratum Header indicates which
is the SCHC Payload end point used for C/D (e.g., so that a receiver
knows how to decompress a packet). Note that the SCHC Stratum Header
itself is also compressed. In the first case (Single-end point
networks), there is only one possible SCHC Payload end point.
Conceptually, this is equivalent to the SCHC Stratum Header being
fully elided, and having a Rule to decompress the SCHC Stratum Header
implicitly known at the receiver.
I reread it now and it's clear: there was the difference in the stratum
header vs SCHC payloads. One question comes to mind here is whether this
is 802.15.4-specific, or not? Won't the same considerations apply to
other networks/technologies using SCHC?
And the terms like single-end point networks; multiple-end point networks.
