[09:10:39] <Xavier Vilajosana> hi everybody!!!!
[09:10:57] <Christian Hopfner> hi there
[09:11:16] <Tengfei Chang> Hello
[09:11:50] Paventhan Arumugam joins the room
[09:12:05] <Xavier Vilajosana> Tengfei!! (Y)

[09:15:40] <Malisa Vucinic> Hi all, I will be your jabber scribe. If you'd like something brought up at the mic, please start your comment with MIC.
[09:15:54] <Thomas Watteyne> hello!
[09:16:04] <Thomas Watteyne> mic OK for remote participants?
[09:16:21] <Christian Hopfner> yes sound is good
[09:17:08] <Paventhan Arumugam> yes, thanks
[09:17:21] <Thomas Watteyne> perfect, thanks
[09:33:29] Tomas Lagos Jenschke joins the room
[09:41:09] Hao Wang leaves the room
[09:42:12] <Xavier Vilajosana> can we use a timeout?
[09:46:40] <Malisa Vucinic> in case of a statefull proxy, that would make sense
[09:46:53] <Malisa Vucinic> in case of a stateless proxy, not really
[10:00:26] Simon Duquennoy leaves the room
[10:00:26] Simon Duquennoy joins the room
[10:10:19] <Thomas Watteyne> we are running a bit late, but we have a 15min buffer at the end, so no worries
[10:10:23] <Thomas Watteyne> @Malisa
[10:11:10] <Malisa Vucinic> thanks!
[10:16:24] Tomas Lagos Jenschke leaves the room
[10:18:27] <Xavier Vilajosana> @Malisa, I mean a timeout for the autonomus cell in the schedule. If the node succeeds through the join process the autonomous cell timeout is cancelled and the cell kept. Otherwise the cell is removed. This is similar to say that there is a limited time to perform the join process.
[10:21:28] <Malisa Vucinic> yes but a stateless JP does not know whether a given pledge joined or not
[10:21:43] <Malisa Vucinic> it could infere, but it would be a layer violation
[10:22:47] <Malisa Vucinic> we need to discuss this further, after join, the pledge might have a new address (short address) so the hash of this address is no longer the same as of the EUI-64
[10:23:58] <Christian Hopfner> @MIC what about installing TX cells only to RPl neighbors?
[10:24:09] <Christian Hopfner> RPL
[10:27:00] <Christian Hopfner> yes not for all neighbors, only parents and children
[10:27:15] <Simon Duquennoy> one issue is, in non-storing mode, nodes do not know their children
[10:27:53] <Thomas Watteyne> @Christian, thanks for clarifying: parents + slides
[10:28:09] Malisa Vucinic leaves the room
[10:28:32] <Christian Hopfner> @Simon can't we derive them from the DAO?
[10:29:12] <Christian Hopfner> or is that only forawarded to the Dagroot
[10:30:29] <Tengfei Chang> @Christian, the DAO is only forwarded to DAGroot in my case
[10:30:40] <Christian Hopfner> ok
[10:31:57] <Thomas Watteyne> @Simon, I will enforce that the last 15min be dedicated to your presentation.
[10:32:19] <Simon Duquennoy> sounds technically feasible but the DAO has the root as destination address. So, it's acting on packets you're relaying. Does IPv6 even allow that? Does even RPL guarantee that the DAO is relayed by the new parent? Might even go on the old path I would say
[10:32:24] <Thomas Watteyne> I think we are confortable on time
[10:37:48] Lorenzo Miniero leaves the room
[10:42:09] <Simon Duquennoy> @Thomas I missed your earlier message. Thanks!
