16:07:14 <sridhar_ram> But, i know most of the core team members will be there .. i hope it will be business as usual
16:07:48 <sridhar_ram> I've requested sripriya to be acting PTL in my absence..
16:08:02 <sridhar_ram> sripriya: thanks for taking this responsibility..
16:08:22 <sridhar_ram> any questions ?

16:12:13 <sridhar_ram> bobh: I've penciled you in to lead the discussion on NSD + Mistral.. would that work for you?
16:12:30 <sridhar_ram> Kanagaraj: howdy!
16:12:41 <bobh> sridhar_ram: yes - should be fine
16:12:54 <sridhar_ram> bobh: thanks!
16:12:55 <trozet> sridhar_ram: is there going to be a virtual meeting so I can dial in?
16:13:36 <sridhar_ram> trozet: we tried it last time, it didn't work as well we hoped it would..
16:13:48 <sridhar_ram> trozet: frankly i could make use of it as well :)
16:13:50 <Kanagaraj> sridhar_ram: hi, fine. thanks :) how are you
16:14:36 <sridhar_ram> trozet: it is a logistical hassle for the team in the room ..
16:14:43 <sridhar_ram> sripriya: what do you think ?
16:15:45 <sripriya> sridhar_ram: we do not know yet the meeting room setup, so there is no guarantee on that
16:15:49 <sridhar_ram> perhaps we can try a "live" etherpad and listen-in only web conference
16:16:10 <sripriya> sridhar_ram; at the leasr we can try to keep the etherpad as updated as possible withe discussions
16:16:24 <sripriya> sridhar_ram: s/leasr/least
16:16:27 <sridhar_ram> sripriya: room allocation will happen soon.. cheddar system to populate the session is open now
16:17:20 <sripriya> sridhar_ram: okay, whats the cheddar system?
16:17:27 <sridhar_ram> sripriya: yes, capturing everything in the etherpad is the best way forward...
16:18:08 <sridhar_ram> sripriya: it is an online tool to populate design summit agenda .. the details then will show up in the summit schedule
16:18:18 <sridhar_ram> sripriya: i'll hook u up w/ that offline
16:18:20 <sripriya> sridhar_ram: got it
16:18:29 <diga_> sridhar_ram: sripriya: I also try to follow etherpad but dont know about setup as i am not able to make it for summit
16:19:18 <sridhar_ram> diga_: no worries diga_ .. as you get closer you will hear the etherpads created for the summit
16:19:29 <sridhar_ram> i think we will branch off the main https://etherpad.openstack.org/p/tacker-ocata-summit
16:20:06 <sridhar_ram> sripriya: heads up, we also need a cross-project sync with networking-sfc team..
16:20:28 <diga_> okay
16:20:32 <sripriya> sridhar_ram: ack, i see that on the summit etherpad schedule
16:20:49 <sridhar_ram> we need to  keep the VNFFG feature healthy with changes coming in that project
16:21:20 <sridhar_ram> trozet: did you hear more on when the network_src_port_id restriction will be removed? That is one item to follow up w/ them
16:21:25 <sripriya> sridhar_ram: probably we need to check if n-sfc team members are available around the schedule time?
16:21:39 <trozet> sridhar_ram: i asked in gerrit, but should follow up with Cathy
16:21:48 <trozet> sridhar_ram: will work on that
16:21:55 <sridhar_ram> trozet: thanks!
16:22:20 <sridhar_ram> trozet: what is the "next" thing to do in the area of VNFFG ?
16:23:14 <trozet> sridhar_ram: well I would like to get it working with ODL,
16:23:31 <sridhar_ram> trozet: sure, that's definitely the top item...
16:23:34 <trozet> sridhar_ram: so right now just trying to get devstack to work then going to try vishnoianil patch
16:23:51 <sridhar_ram> trozet: sounds good..
16:23:55 <trozet> sridhar_ram: then I can help get that patch into networking-odl.  After that there are several clean up items to take care of in Tacker code
16:24:16 <trozet> sridhar_ram: for example we kind of hacked around Tosca to put the 'path' in VNFFGD, we should fix that kind of stuff
16:25:11 <diga_> trozet: My setup is ready with ubuntu16.04, let me know if something to test
16:25:17 <sridhar_ram> trozet: okay...
16:25:20 <sridhar_ram> trozet: dkushwaha: another thing i had in mind was NSD + FFGD in a single TOSCA template
16:25:35 <trozet> sridhar_ram: yeah that woudl help resolve hte tosca parser issues
16:25:56 <sridhar_ram> trozet: may i ask you to list these "items" in the VNFFG section in the https://etherpad.openstack.org/p/tacker-ocata-summit
16:26:19 <trozet> sridhar_ram: yeah
16:26:29 <sridhar_ram> trozet: this will help the team heading to the summit to interact / advise rest of the neutron + sfc team...
16:26:33 <sripriya> sridhar_ram: trozet: what about the ‘symmetrical’ attribute support?
16:27:15 <trozet> sripriya: support for that was just added into networking-sfc, need to follow up
16:27:19 <sridhar_ram> i was planning to send a "state of n-sfc usage in tacker" to armax .. for all his guidance in the last OPNFV Summit @ Germany
16:27:41 <sripriya> trozet: cool
16:27:44 <sridhar_ram> trozet: sripriya: please list these items in the summit etherpad..
16:28:28 <sridhar_ram> bobh: we need a similar interaction with tosca-parser / heat-translator team.. again, is that something you can help facilitate ?
16:28:45 <bobh> sridhar_ram: yes
16:29:15 <sridhar_ram> for both these cross-project, we can either use one of our design summit slot or join theirs'
16:29:31 <sridhar_ram> sripriya: bobh: please make the call as you see fit
16:29:57 <bobh> sridhar_ram: not sure if tp/ht has any slots - I'll check with spzala
16:30:35 <sridhar_ram> bobh: okay, then feel free to use one of our design summit slots..
16:30:38 <spzala> bobh: sridhar_ram: on call but getting back to you in few
16:30:50 <sridhar_ram> spzala: sure..
16:31:21 <sridhar_ram> bobh: sripriya: spzala: in fact it will be nice to hear the "rest" of the things happening in tp/ht world :)
16:31:32 <vishnoianil> trozet, let me know if you need any help with networking-odl driver setup
16:31:49 <trozet> vishnoianil: yeah will come to you for help
16:32:03 <sridhar_ram> bobh: sripriya: spzala: we should purse offering new tosca "features" available through Tacker..
16:32:09 <spzala> sridhar_ram: bobh: if we can use one of tacker design slot (like we did in austin) that would be great
16:32:49 <sridhar_ram> spzala: ack..
16:33:40 <sripriya> sridhar_ram: yeah, it will be good to integrate these new node types from tacker back to tp/ht projects
16:34:29 <sridhar_ram> sripriya: +2 .. lock that room after spzala + tp/ht folks show up unless they agree to this ;-)
16:34:53 <spzala> awesome, so if we can have a joint discussion session we seems can cover good lot of cross projects things
16:36:16 <sridhar_ram> Moving to another topic of interest ... exploring containerized VNFs / VDUs..
16:36:48 <sripriya> sridhar_ram: lol :)
16:37:00 <sridhar_ram> this keeps coming as a question during Tacker evaluations in PoCs..
16:37:10 <spzala> sripriya: sounds great, once you can finalize the time/location for the summit discussion please let me know so that can let other folks in team to know about it .. I am sure most of the folks will attend .. and more folks from tp/ht coming to summit this time
16:37:36 <sridhar_ram> spzala: great!
16:37:51 * sridhar_ram back to containers..
16:38:01 <spzala> sridhar_ram: sure and thank you!
16:38:05 <sripriya> spzala, nice! ack. will sync up with you on the details
16:38:33 <sridhar_ram> I've some thoughts.. but i think we need to first identify user stories / use cases before we "blindly" do that..
16:38:34 <spzala> sripriya: perfect, thanks!
16:39:16 <sridhar_ram> anyone have general thoughts in this area ?
16:40:02 <vishwanathj> are there VNF vendors out there that are delivering the network services in containers already?
16:41:46 <sridhar_ram> vishwanathj: yes, VNFC s/w is available as a container image.. (i don't have a link handy, will find out)
16:41:55 <sridhar_ram> i'll create a section in the summit etherpad for the team to capture container use-cases for Tacker
16:42:19 <sridhar_ram> vishwanathj: IMO we need to explore in two angles ..
16:43:02 <sridhar_ram> 1) How to support traditional VNFCs available in containerized form factor (imagine docker image instead of classic qcow2)
16:43:39 <sridhar_ram> 2) What are the "Network Services" needs in the world of containers app ecosystems
16:43:54 <sridhar_ram> *containerized
16:44:00 <sripriya> sridhar_ram: i think we also need to understand the networking challenges/requirements of these containerized VNFCs…
16:44:03 <vishwanathj> I see ... good points
16:44:54 <sridhar_ram> sripriya: agree.. perhaps (as you had mentioned earlier), we need to look into Kuryr project closely..
16:45:19 <sripriya> sridhar_ram: yeah, need to do some homework on that
16:45:55 <vishwanathj> a useful link to read up on container networking http://thenewstack.io/container-networking-breakdown-explanation-analysis/
16:46:09 <diga_> sridhar_ram: I work on kuryr, this project will surely help us getting neutron network assigned to container network
16:47:04 <sridhar_ram> yes, next few weeks will be good time to do that homework.. and it will be great if the team can write down the user stories (as many meaningful ones as possible) and they we can prioritize and go after the ones that are relative high priority + relatively easier to achieve
16:47:18 <sridhar_ram> diga_: cool
16:47:30 <sripriya> sridhar_ram: sure
16:47:32 <sridhar_ram> vishwanathj: thanks for the link
16:48:06 <sridhar_ram> anything else on this topic of containers for Tacker ?
16:48:49 <sridhar_ram> moving on..
16:48:55 <sridhar_ram> #topic NSD
16:49:13 <sridhar_ram> dkushwaha: can you give an update ?
16:49:36 <dkushwaha> sridhar_ram, Regarding mistral workflow, i have commented in https://review.openstack.org/#/c/304667/
16:49:53 <dkushwaha> sridhar_ram, all, please have a look on this
16:50:42 <sridhar_ram> dkushwaha: thanks
16:51:04 <sridhar_ram> dkushwaha: btw, please add the Mistral pros & cons directly into the spec write up..
16:51:26 <sripriya> dkushwaha: the 4th bullet in cons 1) point is what concerns me as well, going back and forth with tacker and mistral for a nsd request
16:52:13 <sripriya> dkushwaha: sridhar_ram: also, if we needed to have a dependency workfloow between multiple VNFs, should the control come to Tacker after each dependent step completion?
16:53:01 <sridhar_ram> dkushwaha: first, those are nice points..
16:54:02 <sridhar_ram> sripriya: not sure.. again, we need to think a "day in a life" of NSD.. but if i understand the power of mistral many of these back and forth can all be "coded" in the generates mistral workflow
16:54:24 <sridhar_ram> question is how complex that mistral workflow generation logic going to be...
16:54:44 <sripriya> sridhar_ram: right…
16:55:11 <sridhar_ram> dkushwaha: sripriya: the bigger thing that is missing on the pro side .. once we have mistral in place any workflow / remediation already coded will be in the reach of Tacker
16:55:36 <dkushwaha> sripriya, sridhar_ram as we are going with multiple new features, it might be complex for corner cases
16:56:23 <sridhar_ram> dkushwaha: thats a concern for me too..
16:56:59 <sridhar_ram> I'd go w/ the team's decision here.. but let's use this to take a hard look
16:57:24 <sridhar_ram> once we code up NSD directly to tackerclient there is not much incentive to re-write it again using mistral
16:58:10 <sridhar_ram> bobh: your thoughts will be helpful here .. over next few weeks and in the summit
16:58:22 <sridhar_ram> alright we are out of time for today
16:58:44 <sridhar_ram> please continue to review NSD spec
16:58:48 <sridhar_ram> #topic Open Discussion
16:59:19 <dkushwaha> sridhar_ram, please suggest for approach, so that i can move forward
16:59:37 <sridhar_ram> Folks .. i'll be back in few weeks.. will catchup on things in the etherpad...
16:59:46 <sridhar_ram> sripriya: over to you :)
17:00:18 <sridhar_ram> dkushwaha: let the discussion take place in the spec and reach a logical conclusion..
17:00:25 <Kanagaraj> sridhar_ram: take care of you well !
17:00:29 <sridhar_ram> bye folks
17:00:32 <sridhar_ram> Kanagaraj: thanks
