[14:36:14] <Simone Ferlin> I have a question about the scheduler
[14:36:31] <Lars Eggert> ok
[14:36:42] <Simone Ferlin> I would like to know if the delivery is deterministic - related to a TTI for example
[14:36:43] <Lars Eggert> i will relay
[14:36:48] <Simone Ferlin> Thanks!
[14:38:06] <Lars Eggert> hope i didnt mess up your name
[14:38:32] Jana Iyengar joins the room
[14:38:51] Kristopher Price joins the room
[14:40:00] Saverio Mascolo joins the room
[14:41:45] <Simone Ferlin> no, perfect pronunciation :D
[14:41:52] <Simone Ferlin> thanks for forwarding it.
[14:42:37] <Simone Ferlin> The vendor specific part of this work wrt CC makes me a bit worried. The scheduler, resource management algorithm, load at the NodeB, etc.
[14:43:51] <Lars Eggert> if you want me to comment on the microphone, put a mic: prefix in front? otherwise I don't know what's chatter and what are questions
[14:44:10] Vittorio Palmisano joins the room
[14:44:13] <Simone Ferlin> ok!
[14:45:25] <Mo Dong> General question( can be delayed after the presentation): It seems that physical layer is doing a lot of care-feeding for the upper layer to mask packet loss. Is it because TCP is too sensitive to packet loss? Shouldn't this problem (packet loss) then be solved directly in transport layer? What is the loss rate/distribution gonna look like if we just turn off all MAC-layer retransmission?
[14:46:11] <Lars Eggert> ok
[14:46:36] <Lars Eggert> maybe better at the end
[14:46:41] <Mo Dong> yes
[14:47:22] <Mo Dong> thanks
[14:48:01] <Saverio Mascolo> Why TCP Cubic ? should a user get BW in the order of gigabit?
[14:48:22] <Lars Eggert> is that a question for the floor?
[14:48:57] <Saverio Mascolo> for the speaker (and the floor)
[14:49:30] <Lars Eggert> ok (please put mic: in front next time)
[14:49:37] <Saverio Mascolo> ok
[14:49:44] <Lars Eggert> i will ask at end
[14:55:18] <Mo Dong> can you guys hear me?
[14:55:19] <Lars Eggert> meetecho: audio problems for remote speaker
[14:55:23] <Lars Eggert> nor really
[14:55:26] <Lorenzo Miniero> talking to him in private
[14:55:26] <Lars Eggert> trying to debug
[14:55:33] <Lars Eggert> you are really choppy
[14:55:58] Aaron Falk joins the room
[14:56:54] Bo Yang joins the room
[14:57:21] <Lars Eggert> as a netapp person: we're not really that unhappy with TCP :-)
[14:57:41] <Brian Trammell> page 11 of 185?
[14:58:03] <Brian Trammell> ah lots of buildiness
[15:01:38] <Lars Eggert> (i am glad were are not playing the "next" drinking game today)
[15:07:20] <Aaron Falk> +1
[15:08:41] <Lars Eggert> meetecho: we lost audio
[15:08:46] <Lorenzo Miniero> I know
[15:08:49] <Lars Eggert> ok
[15:09:08] <Lorenzo Miniero> he's not responsing privately
[15:09:12] <Lorenzo Miniero> he may have lost connectivity
[15:09:58] Mo Dong_1356 joins the room

[15:36:01] <Simone Ferlin> is the remote slides stuck?
[15:36:05] Mo Dong_7929 joins the room
[15:36:15] <Simone Ferlin> anybody just seeing wrong res. and the first slide only?
[15:36:22] <Mo Dong_7929> me too
[15:36:40] <Mo Dong_7929> only the first slides
[15:36:53] <Simone Ferlin> refreshed, closed/open. still stuck
[15:37:01] <Mo Dong_7929> me too
[15:37:45] <Lars Eggert> still a problem
[15:37:47] <Lars Eggert> ?
[15:38:16] <Mo Dong_7929> yes, do you have the link for the slides?
[15:38:38] <Lars Eggert> hang on
[15:38:50] <Simone Ferlin> https://www.ietf.org/proceedings/96/slides/slides-96-iccrg-4.pdf
[15:38:56] luca de cicco joins the room
[15:39:01] <Lars Eggert> https://www.ietf.org/proceedings/96/slides/slides-96-iccrg-4.pdf
[15:39:03] <Mo Dong_7929> awesome thank you
[15:39:07] <Lars Eggert> although he is doing a live demo now
[15:39:17] <Lars Eggert> of his simulator
[15:39:33] <Simone Ferlin> :(
[15:39:42] <Samuel Jero> Currently pdf page 21
[15:39:53] <Simone Ferlin> thanks
[15:39:56] Eneko Atxutegi leaves the room
[15:39:58] <Samuel Jero> next
[15:40:23] <Samuel Jero> next-23
[15:40:28] Eneko Atxutegi joins the room
[15:47:07] <Simone Ferlin> can you steer the camera to where the slides are projected?
[15:47:17] <Simone Ferlin> maybe we can then follow the demo...?
[15:48:03] <Meetecho> for folks on Meetecho
[15:48:10] <Lars Eggert> i see the camera moving, so meetecho is doing something
[15:48:10] Bo Yang leaves the room
[15:48:11] Bo Yang joins the room
[15:48:16] <Meetecho> apparently the chairs detached our splitter
[15:48:26] <Meetecho> as we're not getting what's on the beamer right now
[15:48:31] <Simone Ferlin> thanks!
[15:48:42] <Meetecho> sorry about that but there's nothing we can do
[15:49:05] <Lars Eggert> chairs are checking
[15:49:10] <Lars Eggert> but would be surprised if they had
[15:49:11] <Simone Ferlin> camera is good now - thanks!
[15:49:21] <Lars Eggert> did it work for earlier talks?
[15:49:34] <Meetecho> we can't access the beamer feed
[15:49:37] <Lars Eggert> i don't think they unplugged anything
[15:49:39] <Meetecho> that only happens when no feed is there
[15:50:03] <Lars Eggert> keith runs some weird X server thingie, where the projector in the room also had trouble
[15:50:08] Mirja K├╝hlewind joins the room
[15:50:13] <Lars Eggert> maybe your thingie on the splitter is not syncing to that
[15:50:32] Bo Yang leaves the room
[15:50:32] Bo Yang joins the room
[15:51:05] <Meetecho> whatever it is, it's preventing us from accessing the beamer feed, sorry
[15:51:39] <Simone Ferlin> leave the camera there!
[15:51:47] <Simone Ferlin> good!
[15:52:05] <Meetecho> Simone Ferlin: we're trying to aim at the slides with the camera
[15:52:05] <Meetecho> *at the screen
[15:53:31] <Simone Ferlin> thanks - its good
[15:53:41] Bo Yang leaves the room

[15:53:58] Saverio Mascolo_6242 joins the room
[15:54:12] <Lars Eggert> let's see if it starts working again with the next presenters laptop
[15:54:43] <Meetecho> (y)
[15:55:49] <Meetecho> still looks like they're using the same one, though?
[15:56:03] <Lars Eggert> yeag, keith still plugged in and showing some stuff
[15:56:05] <Lars Eggert> not sure why
[15:56:59] <Lars Eggert> whatever he is presenting doesn't see to matter to what is being talked about
[15:57:01] <Mo Dong_7929> I agree and same question
[15:57:10] <Lars Eggert> i think he is just running his tool as an ad
[15:58:20] <Lars Eggert> i need to step outside for a minute - can someone else jabber relay?
[15:59:27] Lars Eggert leaves the room
[15:59:33] <Mo Dong_7929> mic: the question is what will happen if turn off MAC-layer loss masking
