| trozet | sripriya: path_id implies the ID that will be used when sending the path_id to networking-sfc to create that chain, that path_id then for an NSH implementation will be used in the packet to identify that path for that chain | 21:43 |
| trozet | does that make sense? | 21:43 |
| sripriya | trozet; doen't nfp id do the same? | 21:45 |
| sripriya | trozet: ^ | 21:45 |
| trozet | sripriya: thats a UUID assigned to manage the nfp in the tacker context right? | 21:46 |
| sripriya | trozet: right, i was understanding how different the path id is from the UUID | 21:46 |
| trozet | sripriya: yeah when folks create SFC they sometimes want to specify the path ID for the chain. This field allows them to do that. It has to be an integer, not a UUID | 21:47 |
| sripriya | trozet: i see, thank you | 21:49 |
| sripriya | trozet: just responded to some of your questions on the spec | 21:49 |
| trozet | sripriya: sorry for the spam but: | 21:49 |
| trozet | 3.3. Service Path Header | 21:49 |
| trozet | 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 | 21:49 |
| trozet | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | 21:49 |
| trozet | | Service Path ID | Service Index | | 21:49 |
| trozet | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | 21:49 |
| trozet | Service path ID (SPI): 24 bits | 21:49 |
| trozet | Service index (SI): 8 bits | 21:49 |
| sripriya | trzoet: do they use this path id integer in their chain? | 21:50 |
| sripriya | trozet: ^ | 21:50 |
| trozet | sripriya: so in NSH version of SFC, that Service path ID goes in the header of the packet. That is what that path ID refers to. It may be used by other SFC implementations (not just NSH) | 21:51 |
| sripriya | trozet: ah ok, | 21:51 |
| trozet | sripriya: yeah that defines which path is which at the SFC level | 21:51 |
| *** dkushwaha_ has joined #tacker | 21:51 | |
| trozet | sripriya: so sometimes an operator will want to control that ID I think, which is why i added it to the yaml | 21:51 |
| sripriya | trozet: in the current template, you have not added it right? | 21:53 |
| *** amotoki has joined #tacker | 21:53 | |
| sripriya | trzoet: sorry, i see it, i missed the ID part initially | 21:55 |
| *** dkushwaha_ has quit IRC | 21:56 | |
| sripriya | trozet: another thought on resource parameters, i see you maintain a 'status' column for each of the resources, are you querying the lower layers for chain, classifier and nfp statuses? | 21:57 |
| trozet | sripriya: yeah i just kind of copied that from the work done on VNFM | 21:58 |
| trozet | sripriya: they have the create_pre, post for the heat driver right | 21:59 |
| trozet | sripriya: while you wait for the heat resource to be created | 21:59 |
| sripriya | trozet: that is going to refactored soon, it was some technical debt we carried from previous design which are getting out of. | 22:00 |
| trozet | sripriya: i think in the future we would change the VNFFG driver to be heat, so we would need the same thing. Maybe for now with just calling neutron we just go active immediately | 22:00 |
| *** s3wong has joined #tacker | 22:00 | |
| trozet | sripriya: how will you refactor it? Don't you have to wait for the heat resource to get created before you update status? | 22:00 |
| sripriya | trozet: i was referring to non heat logic residing in heat esp. for create_device_pre and create_device | 22:01 |
| trozet | sripriya: oh ok | 22:01 |
| sripriya | trozet: regarding the heat stack status, right now we do a polling mechanism to check the stack status and we do not worry about the actual resource status | 22:02 |
| trozet | sripriya: sure stack status | 22:03 |
| trozet | sripriya: but like in _create_device_wait you poll with the driver right? | 22:03 |
| sripriya | trozet: right, from PENDING_CREATE to ACTIVE | 22:04 |
| trozet | sripriya: so if you refactor, you still need some type of mechanism to poll the stack | 22:04 |
| sripriya | trozet: the way we do today is sub optimal with STACK_RETRY_WAIT configured in tacker.conf and again that depends on the machine spec itself where heat is running | 22:06 |
| trozet | sripriya: oh so thats a driver level problem, not the plugin? | 22:06 |
| sripriya | trozet: we need a subscriber model where we can subscribe to heat stack status | 22:07 |
| sripriya | trozet: yes | 22:07 |
| trozet | sripriya: got it | 22:07 |
| sripriya | trozet: in your case, you assume VNFs are already active right since you chain on existing VNFs | 22:07 |
| trozet | sripriya: yeah so i think we will need a similar mechanism in the near future for VNFFG | 22:07 |
| *** mageshgv has quit IRC | 22:07 | |
| trozet | sripriya: right, but if we create SFC as heat stack's we still have to assume it takes time before they are create complete | 22:07 |

| *** dkushwaha_ has joined #tacker | 22:09 | |
| sripriya | trozet: yeah | 22:10 |
| sridhar_ram | trozet: wondering if we need to do some special handling in vnf_delete if that VNF is part of a FFG | 22:12 |
| sripriya | trozet: probably maintaining status at NFP level makes sense | 22:12 |
| sridhar_ram | trozet: .. part of an active FFG | 22:12 |
| trozet | sridhar_ram: yeah exactly VNFM needs to query VNFFG and ask | 22:12 |
| trozet | is it still part of a VNFFG instance | 22:12 |
| sridhar_ram | trozet: argh.. that is a reverse call from VNFM --> NFVO ..hmm | 22:13 |
| sripriya | :) | 22:13 |
| trozet | sridhar_ram: haha well i think there are going to be several cases of that | 22:13 |
| trozet | sridhar_ram: part of the 2 working together to provide VNF and NSO | 22:13 |
| sridhar_ram | trozet: I'm afraid so :-( | 22:13 |
| sripriya | trozet: expand the vnf table to store another column ;) for vnffg_id | 22:17 |
| trozet | sripriya: haha i guess thats better than having to query VNFFG everytime | 22:17 |
| * sripriya wonders if we are going crazy with all these ids! | 22:17 | |
| trozet | sripriya: haha for me its easier to just start writing the code then solve these problems as i hit them. Harder for me to visualize it without being in the code | 22:18 |
| sripriya | trozet: i can totally understand, but we dont want to rewire our code too much also just to solve these problems | 22:19 |
| *** dkushwaha_ has quit IRC | 22:20 | |
| trozet | sripriya: yeah | 22:21 |
| trozet | sripriya: those names in the VNFFGD are names of VNFDs | 22:22 |
| sripriya | trozet: and how will you fetch VNFs from VNFD name? | 22:22 |
| trozet | sripriya: query the VNFM (again >.<) and look for VNFs that were created from that VNFD | 22:23 |
| sripriya | trozet: so you iterate through vnf list based on vnfd_id? | 22:24 |
| sripriya | and then fetch VNFs that match vnfd_id | 22:24 |
| trozet | sripriya: yeah | 22:25 |
| trozet | sripriya: also about the attributes | 22:34 |
| sripriya | trozet: yes | 22:34 |
| trozet | sripriya: so the comment about info needed for the SFC, its actually per virtual link | 22:35 |
| trozet | * VDU.properties.nsh_aware: true # (boolean) | 22:35 |
| trozet | * VL.properties.sfc_encap: vxlan_gpe # (may support more values later) | 22:35 |
| trozet | sripriya: so those properties are what we need to tell the driver about per port pair | 22:35 |
| trozet | sripriya: so those should be defined in the VNFD | 22:36 |
| trozet | sripriya: so I'm thinking we shouldn't list those in the resource right, and just when we query VNFM just pass those values to the driver, and not store them in the VNFFG resource. Does that make sense to you? | 22:36 |
| trozet | my original thought was shove them into attributes as dictionary, but now I'm thinking there is no point | 22:37 |
| sripriya | trozet: those parameters will still need to be parsed from the VNFD template in VNFM tosca utils | 22:40 |
| trozet | sripriya: right, but for VNFFG, he doesnt need to have that in his resource right? Since he will just query VNFM for the values then send it to the driver. he doesnt need to expose it as API or store it in his DB I guess | 22:42 |
| *** dkushwaha_ has joined #tacker | 22:42 | |
| sripriya | trozet: i know it is a lower layer parameter, but will it matter to show it to the user? | 22:43 |
| trozet | sripriya: yeah that's my dilemma :) I think its too low level to show at the VNFFG layer | 22:44 |
| sripriya | trozet: they can always refer the VNFD template | 22:44 |
| trozet | sripriya: yeah lets do away with it for now, then if people ask we can add it later | 22:45 |
| trozet | sripriya: is that OK? | 22:45 |
| sripriya | trozet: if these 2 properties are the only exclusive ones then we can do away with it | 22:45 |
| trozet | sripriya: yeah they are the only ones | 22:45 |
| sripriya | trozet: ok | 22:45 |
| * sridhar_ram notices trozet mentions "he doesn't need to have ..", "he will just query... " | 22:46 | |
| sridhar_ram | leaving VDU and VL attrs in VNFD template make sense | 22:47 |
| sridhar_ram | attrs like nsh_aware | 22:47 |
| sridhar_ram | tosca parser needs support for those.. but tacker can scrub them off before handling the TOSCA DOM tree off to heat-translator | 22:48 |
| trozet | sridhar_ram: ok | 22:56 |
| trozet | thanks for your inputs sripriya, sridhar_ram. I'll try to post a new version of the spec by EOD tmrw | 22:56 |
| sridhar_ram | trozet: sounds good.. | 22:56 |
| * sripriya reckons trozet to take a break ;) | 22:57 | |
| trozet | sripriya: heh at the OPNFV plugfest and getting kind of burnt out for the day :) working on some other stuff atm...beer soon though :) | 22:58 |
| sripriya | trozet: beer/coffee of course! to end the day! :-) | 22:59 |
