[17:36:45] <Matt Zekauskas> anyone know the person at the mic?
[17:37:22] <Ingemar Johansson> Main talker Matt Mathis, Lady is Mirja Kuhlenwind I believe ?

[17:45:10] <Ingemar Johansson> Is Nonce used at all ?
[17:45:27] <michael.welzl> no. but it would be useful!
[17:46:37] <hagen.pfeifer> has mirja running code available?
[17:46:54] <Ingemar Johansson> Also question the need for two alternatives
[17:47:43] <Ingemar Johansson> If alternative 2 is sufficient, then go for that alternative ?
[17:48:45] <michael.welzl> FWIW, on this page you can get an implementation of the nonce (Linux patch) and a paper explaining how you could use the nonce for spurious timeout detection, in a very simple way: http://heim.ifi.uio.no/~michawe/research/projects/spurious/index.html [http://heim.ifi.uio.no/~michawe/research/projects/spurious/index.html]
[17:51:25] <Ingemar Johansson> thx
[17:51:41] <hagen.pfeifer> michael.welzl: thank you, it would interesting if Mirja has actual code reflecting draft-kuehlewind-tcpm-accurate-ecn-option-01 and/or draft-kuehlewind-tcpm-accurate-ecn-01
[17:52:04] <michael.welzl> that i don't know. i just wanted to offer my datapoint about the nonce
[17:52:24] <hagen.pfeifer> i see

[18:01:53] <Michael Tüxen> draft-sabatini-tcp-sack <file:///Users/tuexen/Desktop/tcpm/html%3Fdraft=draft-sabatini-tcp-sack.html>
[18:02:26] fumon leaves the room: Disconnected

[18:11:03] <hagen.pfeifer> Ilpo - Impact of IW10 on Interactive Real-Time Communication
[18:11:35] Wes George leaves the room
[18:13:19] michael.welzl leaves the room
[18:16:57] <Ingemar Johansson> Question : Is the AQM RED or something like CoDel ?
[18:17:42] <hagen.pfeifer> question: How to sum up the results? What is Ilpos IW10 suggestion?
[18:17:56] <Ingemar Johansson> I would believe that CoDel can improve the situation
[18:18:29] <hagen.pfeifer> Ilpos is one of the few linux TCP hackers, if he dont know ... ;-)
[18:18:51] <hagen.pfeifer> but yes
[18:19:09] <Ingemar Johansson> seems to say, don't use IW10 but I believe that bufferbloat is a culprit here
[18:19:36] <Ingemar Johansson> Which draft ?
