RE: [DNA] Best current practice for DNA

[Zhigao Chen <zgchen@psl.com.sg>]

Hi Greg and all,

Recently we submitted a DNAv6 proposal, and the I-D can be found at
http://www.ietf.org/internet-drafts/draft-chen-dnav6-apid-00.txt. Built
on NDv6, the proposal utilizes the generalized "APID", which is
available from L2 hints.

In a nutshell, hosts create the mapping between each already-known APID
and the corresponding default AR information in a so-called APID Cache.
They report unknown APID in RS message and ARs disseminate their on-link
APID to hosts. Based on the APID Cache, a host perceives it stays on the
same link or back to a previous link or is attaching to a new link. When
an APID in a new L3 hint is recognized, it performs reachability test
(using unicast RS/RA exchange) and address validation to ascertain
whether an existing address can be used to fast re-establish L3
connectivity. DAD can be either omitted or done in parallel with DAD
(Optimistic DAD is used in the proposal). Plus, we think the random
delay before sending the RA in reachability test is no longer necessary.
Thus, DNA latency is reduced.

We would like to seek your comments on this I-D and hope it could
contribute to the BCP work in the WG.

Regards,
Zhigao
