[14:05:36] <ROBERT RASZUK> So there is no dual sim iphones ?
[14:05:48] Ralf Lübben joins the room
[14:06:36] <Jing zuo> huawei has dual sim iphone:)
[14:06:48] <Jing zuo> dual sim phone
[14:06:57] <ROBERT RASZUK> Ahhh clearly this is Apple talk :)
[14:07:07] <Jing zuo> :)

[14:08:48] jch joins the room
[14:11:03] dragos joins the room
[14:12:34] <dragos> Actually, the URL is https://datatracker.ietf.org/meeting/99/session/mptcp
[14:15:52] <jch> Seems somewhat wasteful to be using both MP-TCP and a load balancer, but I can see where they're coming from.
[14:17:24] <Jing zuo> i guess the load balancer is some what like a proxy before getting to the server
[14:18:45] <Yoshifumi Nishida> the proposal tries to make it unwasteful
[14:19:09] <jch> Uh-huh. It's actually interesting, I find this application of multipath somewhat unexpected.
[14:27:08] <rolf > if you want to direct a question to the speaker, could you prefix it with "q:"

[14:51:48] Robert Chodorek joins the room
[14:52:59] <Yoshifumi Nishida> Q: when converter change TCP into mptcp, which one will decide it, is it client or converter?
[14:53:50] <rolf > I'll ask in a minute. I let Olivier finish the example
[14:54:56] <Yoshifumi Nishida> thanks!
[14:57:24] <Yoshifumi Nishida> Hmm. you don't want to support the use case where client just support tcp, but utilize mptcp between converter and server or other converters?
[15:05:07] Marcelo Leitner leaves the room
[15:05:51] <wcloetens> q: in the scenario of a middlebox, between an end device with only plain TCP support, and a middlebox talking to a server in the platfrom in MPTCP. Is the "client" the middlebox?
[15:06:10] dragos joins the room
[15:06:47] <wcloetens> the middlebox would implement a TCP proxy for the end device, and send the traffic in mptcp to the converter, or possibly directly to the destination server, if it is detected to support mptcp?
[15:07:40] <rolf > That is a complicated questions
[15:07:44] <rolf > would you please re-send it to the list
[15:11:26] <wcloetens> not really. I may have worded it in a complicated manner. The question is: which use case is being addressed with this? Something like the iOS use case, where the client is a user's end device, or the connection between a middlebox and a carrier's proxy?
[15:12:05] <wcloetens> the "motivation" seems to suggest the latter
[15:12:21] <wcloetens> but the slide shows a mobile device as the client, which would suggest the former
