Hi folks,
I am working on 6lowpan to design some tests and i have got some
questions/remarks about draft-ietf-6lowpan-nd-15 in the Behavior on
Wakeup section (5.8.2).
I think this sentence
> When a host wakes up from a sleep period it SHOULD maintain its
> current address registrations that will timeout before the next
> wakeup.
needs some clarifications.
Even if it's implicit, it doesn't stress enough that a node must
maintain its addresses before switching to sleep mode in order to be
able to retrieve it at wake up time.One may consider it just have to do
so when a node wakes up.
I propose the following sentence that seems more clear to me :
"
When a host plans to switch to sleep mode, it SHOULD maintain its
current address registrations to ensure that they will not timeout
before the next wakeup.
"
Also, i am not sure how to interpret the sentence:
> The
> host may also need to refresh its prefix and context information by
> sending a new unicast Router Solicitation
Does it mean that it is left to the implementation to decide wether a
host refresh its information or not ?
Thanks in advance,
Best Regards,
