[DNSOP] draft-ietf-dnsop-edns-tcp-keepalive-05

[joel jaeggli <[e-mail]>]

From Stephens discuss, this is a question we should probably answer for
ourselves. (it's no longer a consideration as a discuss.

  The question: how does this option play with DNS over
  DTLS? [1]

  The reason I ask is that there may be a need in that case
  for some similar option (or a TLS extension maybe) though
  for the DTLS session lifetime and not a TCP session
  lifetime. At present you are saying that this option is
  not it. And that's a fine answer but you could also have
  said that this could also be used for DTLS session
  lifetime handling. And that last might make sense for
  operational reasons (not sure really, but could be).

My take personally is tcp keepalive option is not the mechanism for
dtls, but then we get multiple options specifying essentially the same
sort of value at some point in the future.

I just want to make sure we have a good reading on this.
