[dnssd] Call for adoption of draft-bellis-dnsext-multi-qtypes into DNSSD

[Chris Box <[e-mail]>]

Dear DNSSD folks,

This message starts a two-week adoption call for
draft-bellis-dnsext-multi-qtypes-08
<https://www.ietf.org/archive/id/draft-bellis-dnsext-multi-qtypes-08.html>,
ending at 23:59 on 30th November in any timezone. As discussed in the
Prague meeting (slides-118-dnssd-multiple-dns-questions
<https://datatracker.ietf.org/meeting/118/materials/slides-118-dnssd-multiple-dns-questions-00>)
this is proposed as a way to permit asking for multiple query types in a
single DNS query message. This would save capacity on Thread networks,
where it is common to need to ask for both SRV and TXT.

An alternative existing design is to achieve this with QDCOUNT=2, but such
a design conflicts with draft-ietf-dnsop-qdcount-is-one
<https://datatracker.ietf.org/doc/html/draft-ietf-dnsop-qdcount-is-one-01>.
That DNSOP draft describes the problems encountered when QDCOUNT>1 and
proposes to require that QDCOUNT<=1.

The chairs consider that draft-bellis-dnsext-multi-qtypes-08 is consistent
with point 2 of the DNSSD charter. Please review the draft and consider
whether you support its adoption by DNSSD. Please share any thoughts with
the list to indicate support or opposition. Note that this is not a vote.

If you are willing to provide a more in-depth review, or are willing to
consider implementing it, please state it explicitly to give the chairs an
indication of the energy level in the working group willing to work on the
document.

WG adoption is the start of the process. The fundamental question is
whether you agree the proposal is worth the WG's time to work on and
whether this draft represents a good starting point.

Thanks,

Chris (for the chairs)
