05:33:45 <vnyyad> Hi
05:33:50 <soichi> #topic: Inclusion in Governance and Neutron Stadium
05:33:53 <reedip> hi vnyyad
05:34:04 <reedip> armax : ping ?
05:34:32 <reedip> I think he is busy  ,but it would be great if we can talk to him about this.
05:34:33 <vnyyad> could not ping him yesterday, will try today
05:34:46 <vnyyad> actually he is on now
05:35:42 <reedip> the basic query is , if we should apply for governance first, and then move onto neutron stadium?
05:35:54 <vnyyad> yes
05:36:19 <vnyyad> can we ask this in the neutron mailing list and try to get some opinion or answer?
05:37:04 <reedip> vnyyad : I think we can .
05:37:48 <vnyyad> reedip: ok... shall we try that then
05:38:20 <vnyyad> anil: any thoughts
05:38:31 <reedip> vnyyad : I think we can
05:39:25 <vnyyad> reedip: so let me put in a mail today
05:40:33 <reedip> vnyyad , lets see if anil_rao has some inputs for this?
05:40:39 <vnyyad> +1
05:41:19 <yamamoto> hi
05:41:30 <soichi> yamamoto: hi
05:43:12 <soichi> anil_rao: do you have any thoughts?
05:45:16 <soichi> let's go on next topic
05:45:27 <soichi> #topic: Performance measurement (progress report)
05:45:49 <kaz> We uploaded a new document about the performance measurement.
05:46:09 <soichi> #link: https://wiki.openstack.org/w/images/e/e9/Increasing_Send_Packets20160921.png
05:46:28 <kaz> Slide 1 shows a performance of the original (community) implementation.
05:47:14 <kaz> The horizonal axis means # of send packets by "iperf -b Npps"
05:47:49 <kaz> the vertical axis means # of received packets and mirror packets.
05:48:22 <kaz> It seems that overhead of mirroring is small if the number of send packets is less than about 70k pps.
05:49:03 <kaz> Slide 2 shows of the flow based tunneling version we implemented.
05:49:03 <soichi> packet size: 64byte (lleft graph) and 128byte (right graph)
05:50:13 <vnyyad> by flow based you mean a filtering based on 5 tuple... before mirroring ?
05:52:16 <kaz> we did not use filtering
05:53:17 <vnyyad> ok can you just elaborate on what flow based meant here
05:53:54 <kaz> We implemented flow based tunneling for separation the production traffic and mirror traffic.
05:54:57 <vnyyad> ha ok... thanks for the clarification
05:56:58 <kaz> Slide 3 shows a comparison of when packet length is 1400Byte.
05:57:42 <kaz> the left graph is original version, and the right is flow based tunneling version.
05:58:46 <kaz> It seems that the received packets with mirror and mirror packets are almost half of the packets without mirror(blue line)
05:59:13 <kaz> It is because the physical network was saturated.
06:00:54 <kaz> Each data of the right graph is almost same bacause of the separation between the production and the mirror traffic
06:01:03 <kaz> to different physical network.
06:02:36 <yamamoto> so everything seem working as expected?
06:03:55 <kaz> yamamoto: yes
06:04:06 <soichi> as a result we can say that trafic separation between production and mirror is effective
06:04:43 <vnyyad> +1
06:06:13 <vnyyad> kaz and soichi: thanks guys!
06:07:05 <soichi> thank you, we will make additional measurements
06:07:48 <soichi> can we go on next topic?
06:08:34 <soichi> #topic: Open Discussion
06:08:55 <soichi> Good news: TaaS presentation proposal was selected for the vBrownBag Tech Talk in Barcelona Summit
06:08:57 <soichi> on 27th Oct., Wedensday, 15:15-15:30
06:10:37 <soichi> we will present performance characteristics of TaaS
06:10:39 <yamamoto> Wed is 26
06:10:58 <soichi> yamamoto: yes, 26th

06:12:54 <soichi> just FYI
06:15:15 <soichi> do you have any other topics or update for today?
06:17:19 <yamamoto> nothing from me
06:17:31 <vnyyad> nothing here too
06:17:34 <kaz> i have no more topics.
06:18:46 <reedip> sorry, I was out
06:19:13 <soichi> reedip: do you have any topic or update?
06:19:50 <reedip> soichi : nothing much as such , but I wanted to know why we cannot create BPs for TaaS
06:20:04 <reedip> vnyyad : Launchpad doesnt allow us to create Blue prints currently
06:20:11 <reedip> for Tap-as-a-Service
06:20:38 <vnyyad> reedip: let me take a look and geet baack to you
06:20:52 <soichi> vnyyad: +1
06:20:56 <reedip> okkkk , vnyyad : I wiiil waiit :D
06:21:34 <vnyyad> :)
06:22:08 <soichi> anything else?
06:23:26 <soichi> it seems we can close today's meeting
06:23:31 <soichi> thank you guys, see you next week
