I found this text
A Page (say Page N) is said to be active once the Page N Paging
Dispatch is parsed, and as long as no other Paging Dispatch is
parsed.
somewhat unclear. Is it saying
A Page (say Page N) is said to be active once the Page N Paging
Dispatch is parsed, and remains active until another Paging
Dispatch is parsed.
?
[Pascal Thubert (pthubert)] Yes, and I like your sentence above better than the
original. The temporal aspect (your "until") still remains to be clarified, as
meaning "as the packet headers are being processed from the first to the last
octet. Do we need to indicated that or is the implicit good enough?
I wasn't quite sure what "so far" meant in this text (and temporal references
in RFCs that live forever are somewhat confusing, anyway).
As a result, there is no need so far for restoring the Page 0
parsing context after a context was switched to Page 1, so the
value for the Page 0 Paging Dispatch of 11110000 may not actually
occur in those packets that adhere to 6LoWPAN specifications
available at the time of writing this specification.
Would this be just as correct with "so far" deleted, or am I not understanding
the point you're making?
[Pascal Thubert (pthubert)] I meant at the time of this publication, there is
no known standard that has a case where page 0 would need to be restored after
switching to page one. Does removing the so far express that correctly?
Thanks for explaining why you're choosing "Specification Required" as your IANA
policy.
[Pascal Thubert (pthubert)] The bottom line is that for most of these 6Lo
networks, there is no equivalent to ethertype. We were already cornered with
the ITU that started using some escape codes without IETF agreement. Now we are
opening a very large namespace, we want it to be used by many communities
beyond IETF, but we also indicate that we wish the IANA to manage that
namespace like the IEEE does for ethertypes; and we wish that non experimental
values are registered based on some standard action not just anyone asking for
one. Now, this question leads to another. Should we reserve one page, say page
15, for experimentations?
Take care,
Pascal
