Re: [DNSOP] [v6ops] New Version Notification for draft-v6ops-xie-network-happyeyeballs-00.txt

I have said before, but don't know if I still adhere to it, but
anyways, here's a question: How *long* do people think a biassing
mechanism like HE is a good idea?

 * is it a good idea *forever*

 * or is it a transition path mechanism which has an end-of-life?

 * how do we know, when its at end-of-life?

I used to love HE. I now have a sense, I'm more neutral. Maybe, we
actually don't want modified, better happy eyeballs, because we want
simpler, more deterministic network stack outcomes with less bias
hooks?

I barely register if I an on v4 any more. I assume I'm on 6 on many
networks. This is as an end-user. I guess if I am really an end user,
this belief I understand TCP and UDP is false, and I should stop
worrying (as an end user)

Extremely, a client can get a better IPv6 connection in one second (when IPv6 win the race), and lose it in next second. In such case, more sophisticated measurement should be done(on client or network) , for a longer period, on statistics of RTT and Failure rate, or combinations of them. But in IMHO, the assumption of HE is relatively stable network for short exchange connections. The dynamics exits but relatively rare or no notable impact on HE. So I see no such discussion in RFC8035.
