15:00:52 <slaweq> hi on qos meeting now :)
15:00:53 <openstack> The meeting name has been set to 'neutron_qos'
15:00:58 <rubasov> hello again
15:01:20 <slaweq> mlavalle: are You with us?
15:01:26 <mlavalle> o/
15:01:43 <slaweq> ok, so let's start
15:01:44 <slaweq> #topic RFEs
15:02:17 <slaweq> there wasn't any new RFE reported recently so I will go through old one
15:02:23 <slaweq> #link https://bugs.launchpad.net/neutron/+bug/1727578
15:02:24 <openstack> Launchpad bug 1727578 in neutron "[RFE]Support apply qos policy in VPN service" [Wishlist,Triaged]
15:02:38 <slaweq> zhaobo6 pushed new PS to his specs https://review.openstack.org/#/c/531074/
15:03:24 <slaweq> IIRC it was almost fine for me (except some nits) but it will need some "vpn expert" to take a look at it also :)
15:03:34 <reedip> hi
15:03:41 <slaweq> I will read it once again this week
15:03:43 <slaweq> reedip: hi
15:04:17 <slaweq> next one is #link https://bugs.launchpad.net/neutron/+bug/1505627
15:04:18 <openstack> Launchpad bug 1505627 in neutron "[RFE] QoS Explicit Congestion Notification (ECN) Support" [Wishlist,Triaged] - Assigned to Reedip (reedip-banerjee)
15:04:33 <reedip> I asked mlavalle to assist in its review just today
15:05:01 <slaweq> yes, I saw You pushed new PS to specs
15:05:03 <reedip> few things need to be sorted out ,and then it should be ready, I would however request all others to review it
15:05:16 <slaweq> I will also try to review it ASAP
15:05:20 <reedip> Its a long time pending , lets get it over with :)
15:05:30 <slaweq> agree :)
15:05:48 <mlavalle> reedip: will you implement it?
15:06:11 <reedip> mlavalle : I hope so, but would need assistance to be honest
15:06:18 <mlavalle> ack
15:06:31 <slaweq> reedip: I hope I will be able to help on that one
15:07:04 <slaweq> but I don't know exactly what will be my priorities in next months so I don't say that I will help for sure
15:07:20 <reedip> slaweq : exactly , same with me for some time
15:07:43 <slaweq> :)
15:08:38 <slaweq> ok, moving on to the next one
15:08:39 <slaweq> #link https://bugs.launchpad.net/neutron/+bug/1560963
15:08:40 <openstack> Launchpad bug 1560963 in neutron "[RFE] Minimum bandwidth support (egress)" [Wishlist,In progress]
15:08:58 <slaweq> I didn't work on it yet
15:09:14 <slaweq> I was talking with Rodolfo about how he wanted to do it some time ago. Basically it looks to be very tricky/hard to implement on backend side for both LB and OVS.
15:10:23 <mlavalle> doable?
15:11:08 <slaweq> To be honest I'm not sure
15:11:46 <mlavalle> has anybody done this kind of QoS in OVS at all?
15:11:56 <slaweq> maybe with some workarounds or limitations
15:12:03 <mlavalle> I might be worth asking in the OVS community
15:12:08 <slaweq> I didn't found anything like that anywhere
15:12:26 <slaweq> yes, I will try to ask about that in ovs ML this week
15:12:29 <slaweq> good idea
15:12:30 <slaweq> thx
15:13:01 <mlavalle> maybe also in the LB community
15:13:07 <mlavalle> if there is such a thing
15:13:27 <slaweq> maybe some Linux communities
15:13:44 <mlavalle> in the case of LB, we would use TC, right?
15:14:12 <slaweq> there are possibilities to do it with IFB devices but as Rodolfo told me that will have some limitations - I don't know exactly what will it be
15:14:21 <slaweq> yes, it has to use TC
15:14:41 <slaweq> in fact in OVS probably also TC would be used underneath
15:14:52 <mlavalle> there must be a group maintaining / developing it
15:15:06 <mlavalle> I mean TC
15:15:14 <slaweq> I will try to search and ask somewhere :)
15:15:15 <mlavalle> maybe we should ask them for ideas
15:16:06 <rubasov> maybe this mailing list is alive (I never subscribed to it, not sure): https://www.spinics.net/lists/lartc/
15:16:52 <slaweq> rubasov: thx, it looks that there are quite fresh mails there
15:16:57 <slaweq> I will ask there also
15:17:01 <slaweq> thank You
15:17:09 <rubasov> hope it helps
15:18:23 <slaweq> ok, moving on
15:18:30 <slaweq> next one is #link https://bugs.launchpad.net/neutron/+bug/1578989
15:18:32 <openstack> Launchpad bug 1578989 in neutron "[RFE] Strict minimum bandwidth support (egress)" [Wishlist,In progress] - Assigned to Slawek Kaplonski (slaweq)
15:18:46 <slaweq> still two small patches related to it, done by lajoskatona in review:
15:18:50 <slaweq> #link https://review.openstack.org/#/c/554532/
15:18:52 <slaweq> and
15:18:56 <slaweq> #link https://review.openstack.org/#/c/552938/
15:19:06 <slaweq> so please review it if You will have some time
15:19:25 <slaweq> rubasov, mlavalle, how specs is going for this one?
15:19:28 <slaweq> any updates?
15:19:33 <reedip> yep, will review
15:19:39 <slaweq> thx reedip
15:19:53 <mlavalle> rubasov and I had a lively discussion exactky a week ago
15:20:20 <mlavalle> the rest of last week I got distracted with multiple port binding
15:20:33 <rubasov> I think we were on the same page at that discussion
15:20:44 <mlavalle> rubasov: yes we were
15:20:53 <mlavalle> I think we are getting closer to a solution
15:21:11 <rubasov> but I'm not sure if we have an overall consensus with all the reviewers of the spec
15:21:21 <mlavalle> jaypipes and seankmooney commented on the nova spec
15:21:29 <mlavalle> I have to go back to their comments
15:21:37 <mlavalle> I will do it today or tomorrow
15:21:44 <slaweq> I will try to read it also once again
15:22:56 <rubasov> IMO the contentious point is: how the RP-tree should look like
15:23:05 <mlavalle> rubasov: yes
15:23:57 <mlavalle> I will try to address that in my next comments
15:24:07 <rubasov> there's a bit of progress in the neutron spec too
15:24:19 <mlavalle> I saw that. Thanks!
15:24:25 <mlavalle> I will take a look soon
15:24:33 <rubasov> just uploaded a new patch set yesterday
15:24:48 <rubasov> mlavalle: thank you
15:25:08 <mlavalle> rubasov: I needed to make progress on multiple port binding last week
15:25:30 <mlavalle> that is why I didn't go back to this spec over the past few days
15:25:30 <rubasov> mlavalle: no problem
15:25:44 <mlavalle> but I will go back this week
15:26:12 <rubasov> mlavalle: looking forward to your comments
15:26:20 <mlavalle> I think that's all as far as progres report on this topic
15:26:28 <mlavalle> in this meeting ;-)
15:26:42 <slaweq> ok, thx for updates :)
15:26:52 <slaweq> so I think we can go to next topic then
15:26:59 <slaweq> #topic Bugs
15:27:20 <slaweq> there was no any new bug reported for QoS since last meeting
15:27:25 <slaweq> which is good IMO :)
15:27:31 <mlavalle> indeed :-)
15:27:35 <rubasov> perfect
15:27:36 <slaweq> we have only on in progress now:
15:27:42 <slaweq> #link https://bugs.launchpad.net/neutron/+bug/1758316
15:27:44 <openstack> Launchpad bug 1758316 in neutron "Floating IP QoS don't work in DVR router" [High,In progress] - Assigned to LIU Yulong (dragon889)
15:27:54 <slaweq> I know that LIU Yulong is working on it still, there is WIP patch pushed: https://review.openstack.org/#/c/558724/
15:28:20 <slaweq> and I think that it's more for some DVR expert to check rather than for QoS side
15:29:08 <mlavalle> seems to be about ready to review
15:29:28 <slaweq> there is WIP in title
15:29:37 <slaweq> that's why I assumed it's still in progress
15:29:49 <mlavalle> I'll ask him?
15:30:05 <slaweq> You are asking if You will ask him?
15:30:06 <slaweq> :)
15:30:17 <slaweq> who except You can know that :D
15:30:48 <mlavalle> slaweq: I asked him
15:30:53 <mlavalle> LOL
15:30:58 <slaweq> ok :)
15:31:28 <slaweq> You asked or You will ask?
15:31:45 <mlavalle> I did
15:31:57 <slaweq> ah, so it's ready to review then
15:32:08 <mlavalle> I asked in the patch
15:32:12 <slaweq> right?
15:32:18 <mlavalle> just left a comment asking
15:32:19 <slaweq> ahh, ok, sorry
15:32:34 * slaweq needs another coffee
15:33:09 <mlavalle> well, maybe you are still very young and can have coffee in the evening. Ican't do that anymore
15:33:43 <reedip> you are not old mlavalle :)
15:33:44 <slaweq> I can drink coffee always :) It's not a problem for me :)
15:34:26 <slaweq> about this patch, I will also do patch to neutron-tempest-plugin which will depend on this one to remove skip of FIP qos test and check if it's working now
15:34:40 <mlavalle> ++
15:35:30 <slaweq> I think we can move on
15:35:32 <slaweq> #topic Open Discussion
15:35:42 <slaweq> anyone wants to talk about something else maybe?
15:36:09 <reedip> nm ...
15:36:26 <mlavalle> I'm good for now
15:36:33 <rubasov> me too
15:36:45 <mlavalle> rubasov: when does gibi_awa1 come back?
15:36:58 <rubasov> he'll be back next week
15:37:05 <mlavalle> :-)
