[23:25:08] <JJMB> discussion
[23:25:33] <JJMB> chesire at mic
[23:25:34] <JJMB> thx for work
[23:25:40] <JJMB> if there is energy by wg
[23:25:45] <JJMB> this work is worth taking up
[23:25:46] DanYork leaves the room
[23:25:54] <JJMB> continuing
[23:27:15] DanYork joins the room
[23:27:18] <JJMB> in hindsight would have pushed harder for use of tcp for earlier work
[23:27:23] <JJMB> thaler at mic
[23:27:31] <JJMB> agrees that work should be taken up by a WG
[23:27:34] <JJMB> ideally DNSSD
[23:27:46] <JJMB> deprecate udp standardize tcp
[23:27:57] <JJMB> thaler suggests simplification
[23:28:13] <Kerry Lynn> Constrained devices??
[23:28:16] <JJMB> no name at mic
[23:28:24] <JJMB> @kerry please elaborate
[23:28:32] <Kerry Lynn> Doug Otis at mic
[23:28:35] <JJMB> if u have a quesiton
[23:28:42] <JJMB> @kerry thx
[23:29:12] <JJMB> andrew sullivan at mic
[23:29:21] <JJMB> comment around why dns is being used for this work
[23:29:28] <Kerry Lynn> I'm concerned about deprecating UDP; some devices may not implement TCP
[23:29:30] <JJMB> not pushing back intensely
[23:29:47] <JJMB> @kerry any examples of devuces
[23:29:48] <JJMB> devices
[23:29:53] <JJMB> lower end, lower power
[23:30:06] <Kerry Lynn> right, 6lo
[23:30:29] <JJMB> are u in the room?
[23:30:33] <Kerry Lynn> We are specifically targeting these devices per the req's doc
[23:30:35] <JJMB> chesire at mic
[23:30:38] <Kerry Lynn> I am remote
[23:30:40] <JJMB> agree with thaler
[23:30:51] <JJMB> this work does not step on toes of dprive
[23:31:02] <JJMB> @kerry
[23:31:13] <JJMB> if u need me to approach the mic please let me know
[23:31:51] <Kerry Lynn> Just please note that we are also required to support constrained devices, which may not support TCP.
[23:31:51] <JJMB> analysis is not documented other than the slides
