20180306 Meeting agenda and Minutes

1) DM:                     Anatoly Katzman

?Victor’s proposal will be agreed – TOSCA NFV profile plus R2 IM+

https://wiki.onap.org/display/DW/Data+Model+align+with+TOSCA+NFV+Profile

Note: need to confirm whether onboarding has any issue, if fail then need to fall back to R1 solution.

1) will keep onap type and heat type both folders, and

2) will update onap type with TOSCA NFV profile, and

3) will best effort to let 2 use cases use it, if fail, and will fall back to heat type , and

4) will work on improve R3 modeling spec before end of Beijing release

Extra addition related to IM+(including HPA) will be added later


2)Resource IM:        Xu Yang

1? ElementGroup enhancement:

agreed to put them as “experimental” (optional to implement) part of the R2 model, except for scalingGroup which needs further discussion

2? HPA support:

agreed to support the feature in R2 IM

regarding the attributes, 2 concerns have been raised:

l  The definition/specification of the key and value of each attribute is not clear, which makes it hard for people to understand the usage of each attribute and agree on including it into the IM

l  There’re a few attributes in the IM having the same functionality as the HPA attributes (considered as legacy/redundant attributes). Some participants have shown their preference on choosing one way to express certain functionality, e.g., cpu pinning

a poll has been set up to decide which attributes to be included in R2 IM and how people want to deal with the “legacy/redundant attributes”

https://lf-onap.atlassian.net/wiki/display/DW/HPA+Attributes+Poll

3? L3AddressData attributes & Polling results:

No time to discuss


3)Service IM/DM:    Lingli Deng & Maopeng (Wednesday call)

1)DM:               Anatoly Katzman (Anatoly is absent due to traveling, Deng Hui help to lead the discussion)

    1.1) AT&T suggest to keep Heat support , agreed

    1.2) two tosca proposal on the table

       a) https://wiki.onap.org/display/DW/Data+Model+align+with+TOSCA+NFV+Profile

       b) https://wiki.onap.org/display/DW/Data+Model+Compliance+with+ETSI

    Suggest a will be R2, b will be a new proposal for R3+ (Consensused), Intel question whether we need b proposal

       Intel: support SOL001/TOSCA NFV DM or code contributor

       ARM: support SOL001

       AT&T(Andy) support TOSCA NFV DM for onboarding,  along with Heat

       Nokia:  support SOL001, code contributor(check)

       Ericsson: support SOL 001/TOSCA NFV DM ,code(check)

       Huawei: support SOL001/TOSCA NFV DM code contributor

       ZTE:  support SOL001/TOSCA NFV DM code contributor

       China Mobile: support TOSCA NFV DM code contributor

Comments:

    a) current ONAP IM is more than IFA 11, we need to follow ONAP spec

    b) China Mobile question on SOL001 IPR issue, OASIS TOSCA is more IPR friendly.


2)Resource IM: Xu Yang

      community agreed to do majority vote for the not agreed attributes in the end.

20180213 Meeting agenda and Minutes

1)  Resource IM YANG Xu

there is no consensus whether we need to follow ETSI NFV naming convention or change into ONAP naming.

Two polls will be set to decide the naming convention and future meeting time. The polls close on Feb 28th.

https://lf-onap.atlassian.net/wiki/display/DW/Meeting+Time+Poll

https://lf-onap.atlassian.net/wiki/display/DW/Naming+Convention+Poll

 

2)  Data modeling Anatoly Katzman

DENG Hui: modeling subcommittee have to finalize the 1st draft version by M3 deadline, in this case, we need to allow solutions only 1 week, and make the decision on Feb. 28th.

DENG Hui: there are two solutions on the table now: Monolithic VDU design and TOSCA NFV profile, we are not make decision today, but would get basic impress what company would like to follow:

Vendors:

1) Ericsson  vote for  of ETSI NFV Profile

2) ZTE   vote for  ETSI SOL NFV profile

3) Huawei vote for  ETSI NFV profile

4) Nokia --no one on call

5) Netcracker (Priya TG) vote for ETSI NFV Profile

Operators:

1) AT&T: Monolithic VDU

2) China Mobile: lacking information to do an informed comparison hence no strong opinion to any specific proposal currently. The options on the table should firstly meet the requirement as a unified DM in the community with consistency to the IM and implementable in Beijing release cadence with vendors support. It would be better if we could align with SDO in the same time.

Next step:

a) check whether we have 3rd solution or not in a week

b) make decision on Feb.27th

3) Modeling tool poll(Jessie)

1) use github for papyrus revision

fine from IM's team (Kevin, Andy, Lingli, and YANG Xu)

Anyway, polling will end by the end of Feb.

 

20180207 vF2F modeling subcommittee session:

1)  Resource IM Xu Yang

2)  Service IM Maopeng Zhang

3)  Data modeling Anatoly

4)  Centralized Parser Atul

Atul will keep weekly calls for Parser Tiger team from w/c 12th Feb

-  Infosys will help in preparing user stories and requirements, criteria, plan on a page for proposed PoC activity, this will happen as part of modelling project and along side ZTE’s OPNFV parser proposal

- this  PoC will look at various points like

  1. API access of this Parser As a Service, can that be standardized

  2. Exception handling of this interaction

  3. Can a placeholder be created in modelling project to on-board various parsers and abstract them with an API consumers of this idea, what will change for them

  4. The outcomes of this PoC activity may decide if R3 gets a proper / proven proposal for consideration or if the idea is not feasible, it may be dropped

- at the end of PoC, a final call will be take and summary presented to modelling subcommittee to decide on whether it makes sense to peruse this idea further or learnings from the same

5)  Modeling tools Nigel

6) Projects follow up modeling spec discussion (Modeling contact from each Project)
