Dear NSA authors,
Please find below a few comments/questions on your NSA drafts.
1.- draft-li-6lo-native-short-address-03
****************************************
- In the paragraph before Figure 2, the draft refers to "LOWPAN_IPHC's 7
octets". The text reads as if that (7 octets) was the only possible
compressed IPv6 header size when using RFC 6282. However, with RFC 6282,
it is possible to fully elide source and destination addresses (leading to
a 3-byte compressed header, when context is used), and it is also possible
to have compressed IPv6 header sizes greater than 7 bytes, depending on
how header compression is used.
- In Figure 2 there is a header field called "AM", whereas it is "MA" in
Figure 6.
2.- draft-li-nsa-reliability-00
*******************************
- In section 3, the draft states:
"In the specific case of NSA
[I-D.li-6lo-native-short-address], all nodes, except the root, have
at least one secondary parent"
Is this a feature of NSA enforced by design?
It might be helpful to discuss in the document(s) how scenarios
without a secondary parent are supported. For example, a string
topology, such as:
A ----- B ----- C ----- D
Thanks,
Carles (as a WG participant)
