Hello Ted and Tom, I'm going to reply to both of you at once. First of all, I'm not going to push for wire format change any longer. Your replies show that there is a lot of thoughts behind the document *but* these are not captured in the document itself nor dnsop mailing list. (Maybe I'm just i

Hello Ted and dnsop, I'm trying really hard to find out why we do not understand each other so I dug into to dnsop archives and draft-bellis-dnsop-session-signal-00 to see if my questions were already answered somewhere. Hopefully I have better understanding and will focus on technical questions.

Petr, forgive me for holding your feet to the fire on this, but you make several statements along the lines of "for me, ... is stretching the definition too far," "I disgree that this is less significant," et cetera, but you don't actually raise any technical objections—you just expressed uneasy fe

Hello Ted and dnsop, and sorry for delayed answer (below). Your message forced me to think more about the draft, this time without focus on the wire format. Spoiler alert: I still do not like the proposal in its current form. Please see below. On 21.7.2017 10:22, Ted Lemon wrote: > I am hearing

I am hearing from a number of people that this is "a new protocol" and hence requires careful thought and perhaps a new working group, along with the associated delay. I do not _entirely_ disagree with this position, although it would be really inconvenient from my perspective. However, I would

For TCP connections, being able to signal session liveness policy is useful for DNS, not just DNSSD. It seems likely that DNS Push is useful for things other than DNSSD. I think this is generally useful, not just for DNSSD. Rather than thinking of this as a DNSSD-specific enhancement, think o

Hey, there's one thing I don't really understand from this draft. Is this useful for DNS at all, or is this targeted at DNS-SD only? I think this needs some explaining and perhaps a clear cut is needed. Although it's not mentioned anywhere in the document, the draft makes much more sense to me,

Hi, I have one comment for this draft. In Section 3.3 Message Format, I would prefer that if a Session Signaling message is received where any of the section count fields are not zero, the receiver MUST respond with an error code, e.g. FORMERR, but MUST NOT terminate the connection. My reason i
