[16:51:54] <csp> Do we merge with draft-ietf-taps-transports-usage? No
[16:52:05] <csp> Update on draft-gjessing-taps-minset-02 - Michael Welz presenting
[16:56:39] <csp> Q: does “automatable” prohibit the application from controlling the features? (Aaron Falk) no
[16:57:26] <csp> Q: is this draft done? No. Updates coming.
[16:58:27] <csp> “On the cost of using happy eyeballs…” - Anna Brunstrom presenting
[16:59:53] <csp> Slides based on IRTF ANRW paper: https://irtf.org/anrw/2016/anrw16-final27.pdf
[17:08:51] <csp> Q (Tommy Polly, Apple): how parallel are the connection requests - simultaneous? Yes.
[17:09:43] <csp> Their (Apple’s) experience with IPv4/IPv6 Happy Eyeballs shows that biasing in favour of one protocol can significantly reduce costs. Can they do something similar for transport protocols?
[17:10:37] <csp> Anna has a-priori preference, but no learning and caching
[17:11:38] <csp> Q (Stephen Strowes, Yahoo): like the idea. how does happy eyeballs at the transport interplay with happy eyeballs at the network layer?
[17:12:02] <csp> How does it relate to ICE?
[17:12:23] <csp> Anna: Not studied
[17:12:38] <csp> Tommy (Apple): they have some experience. Needs to be done with care.
[17:14:26] <csp> Q (varun singh): ICE wg has related results; cullen jennings has data. they see 30+ candidates for ipv4/v6 today. this will make much worse.
[17:15:05] <csp> varun: congestion control for this is hard
[17:16:38] <csp> Colin Perkins: this happy eyeballs is essentially ICE. scope for coordination
