[07:55:48] Lotte Steenbrink joins the room
[07:56:00] <Michael Richardson> btw (for the minutes, not the mic), ricahrdson-6tisch-join-enhanced-beacon is "00" version of 6tisch-roll-join-priority.
[07:56:43] Maria Ines Robles joins the room
[07:56:59] <Maria Ines Robles> How it is the sound
[07:57:29] <Maria Ines Robles> I will be your jabber scriber, please let me know if you need something
[07:57:29] <Michael Richardson> sound is all good.
[07:57:40] <Maria Ines Robles> great, thanks Michael
[07:58:14] Simon Duquennoy joins the room
[07:58:52] <Michael Richardson> no wait. I'm wrong!!!!  They are different documents for different purposes, now I recall!
[07:59:01] <Michael Richardson> (just for the minutes_)
[08:00:05] <Maria Ines Robles> ok
[08:00:07] <Michael Richardson> (I forgot all about 6tisch-roll-join-priority....)
[08:00:34] <Maria Ines Robles> that doc can go to ROLL I think
[08:00:47] <meetecho> Is Xavi too loud in the room, or is he ok?
[08:00:55] <Maria Ines Robles> Is ok
[08:00:59] Jonathan Munoz joins the room
[08:01:00] <meetecho> (y)
[08:01:34] Thomas Watteyne joins the room
[08:02:24] <Thomas Watteyne> meetecho, Xavi is a bit loud
[08:02:36] <meetecho> Thomas Watteyne: I'll try to lower the playout volume
[08:02:41] <Thomas Watteyne> thanks
[08:03:53] <meetecho> Better now?
[08:03:57] <Maria Ines Robles> Yes
[08:07:27] Geraldine Texier joins the room
[08:09:15] <Maria Ines Robles> Malisa
[08:09:41] <Xavier Vilajosana> malisa we cannot hear you
[08:09:44] <Xavier Vilajosana> yes
[08:15:24] Lijo Thomas leaves the room
[08:15:26] Lijo Thomas joins the room
[08:15:34] Lijo Thomas leaves the room
[08:15:59] Lijo Thomas joins the room
[08:17:43] Diego Dujovne leaves the room
[08:17:56] Diego Dujovne joins the room
[08:19:04] <Michael Richardson> Thomas: if it's the wrong network, then you have to timeout. But you had to do that anyway, because you can't trust the negative reply anyway.
[08:19:24] <Maria Ines Robles> MIchael
[08:19:31] <Maria Ines Robles> do you want me to put in the mic?
[08:19:31] <Michael Richardson> (not needed mic)
[08:19:35] <Maria Ines Robles> ok
[08:22:19] <Thomas Watteyne> @Michael, agreed
[08:24:12] <Michael Richardson> @Thomas, previously the reliability came from the "TCP" layer (which is actually CoAP), now it comes from the application.
[08:24:29] <Thomas Watteyne> yep, understood
[08:24:35] Lijo Thomas leaves the room
[08:24:37] Lijo Thomas joins the room
[08:27:27] <Maria Ines Robles> Raul at mic
[08:29:38] <Maria Ines Robles> Goran at mic
[08:29:57] <Michael Richardson> @Goran, but MISSREF will sort out the timing, if the documents are done.
[08:30:20] <Maria Ines Robles> MIchael
[08:30:23] <Maria Ines Robles> at mic?
[08:31:09] <Maria Ines Robles> ok
[08:32:35] <Michael Richardson> mic: Suresh, but zerotouch-join still uses certificates, and could depend upon EDHOC.
[08:34:50] <Maria Ines Robles> Michael
[08:34:55] <Xavier Vilajosana> you felt slep Michael?
[08:34:55] <Maria Ines Robles> we can not hear you
[08:35:32] <Thomas Watteyne> @Michael, we hear you now
[08:35:39] <Thomas Watteyne> @Diego, ready? you're nex
[08:37:57] <Diego Dujovne> hopefully. had connectivity issues about 10 minutes ago
[08:38:18] <Maria Ines Robles> Goran at mic
[08:38:19] <Diego Dujovne> if murphy helps, I will have them back when I try to speak.
[08:39:16] <Thomas Watteyne> @Diego, ok, let's hope all goes well
[08:42:17] <Maria Ines Robles> Peter van der Stock at mic
[08:43:02] <Maria Ines Robles> Diego
[08:43:08] <Maria Ines Robles> we can hear you
[08:43:59] Lihao Chen leaves the room
[08:44:01] Lihao Chen joins the room
[08:44:33] Ann Krieger joins the room
[08:45:19] Abdur Rashid Sangi leaves the room
[08:47:48] <Lijo Thomas> Does Diego has any experimental results currently available.. I mean in terms of stability etc;
[08:49:03] <Simon Duquennoy> ASF: "Autonomous SF"
[08:49:28] <Thomas Watteyne> Thanks @Simon
[08:49:48] <Maria Ines Robles> answered Lijo?
[08:49:55] <Lijo Thomas> thanks !!
[08:50:15] <Simon Duquennoy> :D
[08:51:02] <Thomas Watteyne> @meetecho, can you put Tengfei louder?
[08:51:11] <meetecho> (y)
[08:51:43] <meetecho> Is it better now?
[08:51:49] <Maria Ines Robles> yes, thank you
[08:53:00] <Thomas Watteyne> it's perfect now, thanks!
[08:57:10] Abdur Rashid Sangi joins the room
[08:57:27] Lihao Chen leaves the room
[08:57:31] Lihao Chen joins the room
[08:58:10] <Diego Dujovne> In slide 8, how did you deifne those values? 16,12,4?
[08:58:19] <Maria Ines Robles> mic?
[08:58:31] <Diego Dujovne> if possible.
[08:58:34] <Thomas Watteyne> @Diego, you can jump into the line mic
[08:58:48] <Diego Dujovne> Ines volunteered.
[08:58:51] <Thomas Watteyne> thanks
[08:59:01] <Maria Ines Robles> i will do
[08:59:05] <Thomas Watteyne> @Diego, maybe not when someone else is presenting remotely
[08:59:08] <Thomas Watteyne> thanks Ines
[08:59:10] <Maria Ines Robles> at the end
[09:00:13] Abdur Rashid Sangi leaves the room
[09:00:20] Abdur Rashid Sangi joins the room
[09:00:38] <Maria Ines Robles> Diego, answered?
[09:00:50] <Diego Dujovne> ok
[09:03:31] <Simon Duquennoy> The cells to pref parent are for Tx only, or also Rx?
[09:03:39] <Maria Ines Robles> mic?
[09:03:59] <Simon Duquennoy> sure!
[09:04:07] <Maria Ines Robles> ok
[09:04:51] Abdur Rashid Sangi leaves the room
[09:04:55] <Simon Duquennoy> ok txs for clarifying!
[09:04:55] <Maria Ines Robles> Simon answered?
[09:04:57] <Maria Ines Robles> ok
[09:04:58] <Simon Duquennoy> yes txs
[09:05:02] Abdur Rashid Sangi joins the room
[09:05:04] <Thomas Watteyne> @Simon, both TX and RX
[09:06:05] <Malisa Vucinic> MIC: we count the number  of cells with the old parent and add the same number of cells with the new one
[09:06:20] <Malisa Vucinic> in a single 6P transaction
[09:06:22] <Xavier Vilajosana> yes
[09:06:27] <Maria Ines Robles> ok
[09:06:31] <Xavier Vilajosana> all at once
[09:06:33] <Malisa Vucinic> thanks :)
[09:06:54] <Maria Ines Robles> ok
[09:07:49] <Thomas Watteyne> @meetecho, can remote people ask mic questions when there is another remote presenter?
[09:09:17] <Thomas Watteyne> @Michael, there is a possibility that your 2nd presentation gets suqeezed
[09:09:25] <Thomas Watteyne> we are running over...
[09:09:57] <Diego Dujovne> mic: would it be nice to see traffic burst conditions on the experiments
[09:10:01] <Maria Ines Robles> Charlie Perkins ayt mic
[09:10:26] <Michael Richardson> @Thomas, not a problem.  Maybe just do WG adoption call on enhanced beacon document.  I don't know what to do with the ROLL option.
[09:10:30] <Michael Richardson> (not mic)
[09:10:42] <Malisa Vucinic> diego, we did this in the simulator
[09:11:15] <Malisa Vucinic> they are on the simulation result slide
[09:11:32] <Diego Dujovne> yeap, but the experiments are the ones which suffer real conditions
[09:11:33] <Thomas Watteyne> @Tengfei, we still see you
[09:12:15] <Thomas Watteyne> @Michael, makes sense, we will discuss with Pascal right after meeting and take action immediately
[09:12:23] Tengfei Chang leaves the room
[09:12:29] <Malisa Vucinic> how the algorithm converges can also be seen in the simulation
[09:12:32] Tengfei Chang joins the room
[09:12:41] <Diego Dujovne> in fact, the code is different between 6tisch simulator and openwsn
[09:12:42] <Malisa Vucinic> and also how it adapts to the bursty traffic
[09:12:50] <Xavier Vilajosana> i think that the simulation can bring more information as we can reach the limits
[09:12:59] <Malisa Vucinic> could be, we implemented independently
[09:13:04] <Xavier Vilajosana> the real conditions are really constrained by the setting
[09:13:09] <Malisa Vucinic> this is still prelimenary
[09:13:43] <Diego Dujovne> exactly. but the platform can be used to generate more realistic conditions
[09:14:17] <Diego Dujovne> (it should be used for that, though)
[09:14:25] <Malisa Vucinic> realistic in what sense? link-layer drops? traffic pattern?
[09:15:01] <Diego Dujovne> traffic pattern generation, phy-layer interference
[09:15:41] <Malisa Vucinic> I agree we cant have completely realistic behavior on the link but we do introduce drops probabilistically in the simulator. However, I dont see any difference in how you generate traffic between the simulator or a real app...
[09:17:14] <Diego Dujovne> when you generate real traffic, it goes through the stack on every node and suffers processor limitations
[09:17:30] <Diego Dujovne> plus other resource clogs
[09:17:52] <Diego Dujovne> which are not seen on the simulator,
[09:19:31] <Malisa Vucinic> if a node trasnmits periodically with a period on the order of 15s, I am not sure how much does processing delay on the order of ms affect the traffic pattern in the network.
[09:19:51] <Xavier Vilajosana> bye!
[09:20:01] Geraldine Texier leaves the room
[09:20:01] <Simon Duquennoy> bye!

[09:20:45] Malisa Vucinic leaves the room
[09:20:51] <Diego Dujovne> (in fact, it does affect. I jope I could make things work as in simulator always)
