[dna] Comments on Simple DNA

[JinHyeock Choi <jinchoe@gmail.com>]

Dear Suresh & Greg

Here are the issues I mentioned during Dublin meeting. I post them
before I lose them.

1. Verification of IP address per router.
Previously DNA relied on link identification. So a host verifies all
addresses (and IP parameters) at a stroke. However Simple DNA aims to
verify IP address (and IP parameter) per router. I propose we write
down the change clearly.

2. Verification procedure
I have difficulty grasping the exact verification procedure. If you
provide pseudocode as Sathya did in Sec 5.2.6.1. of DNAv6, that would
be of help.

3. Two kinds of IP addresses
Simple DNA host should keep both operable and valid IPv6 addresses.
Their meaning are much different, so we'd better take more care with
the terms such as 'valid' or existing'. For example, in abstract, it's
written that

   Detecting Network Attachment allows hosts to assess if its existing
   addressing or routing configuration is valid for a newly connected
   network.

However, I assume, you meant that "host assess whether its addresses
are operable" because it only have to check prefix lifetime to assess
whether an address is valid.

4. Applicability statement
Please write down that simple DNA is to optimize for visiting
previously attached link.

Thanks for your kind consideration.

best regards

JinHyeock
