[21:14:06] <jgunn> I am hearing nothing
[21:14:38] <billvs> can you hear now?
[21:14:44] <kmirja> yes
[21:14:45] <Lorenzo Miniero> Slide 2: Changes since -03 version
[21:14:46] <ijjarvin> yes
[21:14:50] <jgunn> very faint

[21:16:30] Dave Taht leaves the room
[21:16:44] <Lars> is the audio faint for everyone, or just jgunn?
[21:19:02] <kmirja> audio is okay for me
[21:19:47] <jgunn> I am using the audio link on the "tools agenda".  Is there another link that will work better?
[21:20:04] <Xiaoqing Zhu> i'm following this one too. seems ok
[21:20:10] <kmirja> i'm using the same
[21:20:14] <Xiaoqing Zhu> a bit low, but i can hear everything
[21:20:20] Dave Taht joins the room
[21:20:21] <Lorenzo Miniero> Slide 4: Evaluation Methodology
[21:20:22] <kmirja> same here
[21:20:25] <Lorenzo Miniero> rtsp://meetecho.meeting.ietf.org/e3kwv3m.sdp
[21:20:47] <Lorenzo Miniero> this is the RTSP link from our Meetecho streaming
[21:20:49] <Lorenzo Miniero> if you just want the audio and are not interested in the other stuff
[21:21:09] <Lorenzo Miniero> I've just monitored it and the audio levels seem ok
[21:21:34] <Lorenzo Miniero> Slide 5: Next Steps
[21:21:39] <Xiaoqing Zhu> question for slide #4: the first two are for simulation
[21:21:53] <Xiaoqing Zhu> the third one is for testbed?
[21:21:56] <Lorenzo Miniero> Meetecho as a whole available here instead: http://www.meetecho.com/ietf88/rmcat

[21:36:45] <Xiaoqing Zhu> Question for single-link scenarios (slide #4):  they seem to overlap with the scenarios on the google site
[21:36:50] <Xiaoqing Zhu> except for link rate
[21:37:07] <Xiaoqing Zhu> how are we going to reconcile that?
