[16:38:21] <J Ignacio Alvarez-Hamelin_web_141> For the Morton presentation: You must keep in mind that speedtest.com takes one minute to make its measurements: this is what is runing today in the Internet.

[16:38:34] Feng Yang_web_355 joins the room
[16:38:42] <Gorry Fairhurst_web_521> Perhaps the UDP Guidelines numbers and statements on CC requirements helps define the reactions that might be helpful?
[16:38:44] <J Ignacio Alvarez-Hamelin_web_141> I am not afraid that some packets are lost in this kind of measurements.
[16:39:11] Feng Yang_web_355 leaves the room
[16:39:36] <J Ignacio Alvarez-Hamelin_web_141> Perhaps we have to reach some agrement on the parameters related to the RTT and capacity of the download-upload link.

[16:43:58] <Eduard V_web_319> Sorry for the stupid question: is this measurement better than iperf3? I do not know details of how iperf3 operates, but it is probably possible to investigate.

[16:45:28] <Ian Swett_web_989> <as an individual, I wonder if it's worth ensuring this conforms to RFC8085?>
[16:45:32] Cheng Zhou_web_191 leaves the room
[16:46:00] Cheng Zhou_web_688 joins the room
[16:46:08] <Ian Swett_web_989> Gorry, are you thinking of RFC8085?
[16:48:17] Gyan Mishra_web_401 joins the room
[16:48:44] <J Ignacio Alvarez-Hamelin_web_141> Perhaps it is similar in certain way, lets a look: https://iperf.fr
[16:49:39] Gyan Mishra_web_401 leaves the room
[16:49:41] <Gorry Fairhurst_web_521> Yes, this describes various way in which apps can operate and how circuit breakers could be used, or fixed timers, etc.
[16:50:09] Gyan Mishra_web_321 joins the room
[16:51:14] <J Ignacio Alvarez-Hamelin_web_141> iperf has some issues with TCP, I think this work tries to sep up the simplest way to do the job considering IETF standars.
[16:51:27] <J Ignacio Alvarez-Hamelin_web_141> And also measures other things

[17:58:20] <Ruediger Geib_web_173> @Martin: I think, Greg proposes to combine end-to-end BFD with STAMP/TWAMP. He's monitoring performance and availability of and end-to-end path then, I guess. My propsal relates to sub-path monitoring within an SR domain.
[17:59:51] <Martin Duke_web_232> @ruediger thanks
