Meeting minutes
1) R2 service modeling will be the same as R1 servcie modeling which is confirmed by SDC/SO/HPA/VNFSDK/AAI/VFC
...
- Cardiality correction by John
- Suggest to move to composite pattern instead of recursive aggregation
- Decoration pattern is FFS
- Terminology need to be defined (e.g. clarifications on service component as with the one in MEF)

• ONAP R2+ service IM Discussion Review
...
- Service Order (Andy/Kevin) - Skipped for lack of presenter
- Service Component:
- Network Service Descriptor (Maopeng Zhang)
NSD IM: If no furture comments on the NSD IM are received next week, it will moved into the clean page.
NSD DM: R2 NSD Model as resource was discussed. SDC has supported NSD node definition, and more detail is needed discussed with SDC team.Thinh requests to accelerate the NSD data model
- Service Component: WAN Service Descriptor (Zhuoyao Huang)
Nigel suggested 3 options for improvements to ONAP WAN model:
Option 1 (Core overlay): Follow CIM concept, LC/XC is FC, import LTP and Link, node is FD but not NE.
Option 2 (TAPI overlay): Follow TAPI concept, LC/XC/FC is connection, FC port and XC point replaced by CEP and NEP, import Topology.
Option 3 (M.3100 overlay): Change some names for aligning with ONF IM concepts( following ITU-T Recommendation M.3100 ) better and keep the UML class topology of original WAN IM proposal:
WAN IM

Forwarding Construct
SNC(Subnetwork Connection)
FC Port
CTP(Connection Termination Point)
Node
SN(Subnetwork)
FC Route
SNCRoute(Subnetwork Connection Route)
XC Port

- Network Service Descriptor (Maopeng Zhang)
...
- The current status of service IM and my observations (Xu Yang) - delayed due to time limitation
- Discussion for follow-ups
- Lingli provides customer-facing business scenarios as input for service model discussion and comparison by Tuesday;
- For Friday workshop, each presenter (including SDOs/individuals) is expected to provide their respective proposal models and with the context of customer facing business scenario;
- Based on which, the team is expected to develop a more clearly scoped target and collaborative pattern for R3+.

Andy suggested to add service order model to the agenda.
Hui suggested to add VNFD DM discussion for finalizing R2 spec. R2 Status summary and priority
Agreed to continue work on nsd for R2 implemenation, and defer WAN descriptor discussion for R3 discussion starting next call.
And service order proposal to R3 discussion.ONS workshop agenda
Deng Hui suggest to- Add project PTL to explain how they implement service today SDC, SO, A&AI
- YANGXU is presenting the relationship between SERVICE and network service
- Multi SDO presentation about service IM , tmf/mef/onap
- Offline to build tiger team to design service IM
Andy suggest to
- Add service order model
- Further Discuss NS
- Network Service Descriptor R2 Implemenation Discussion
NS model as service component added in the R2.
Maopeng and Anatoly need to discuss more tosca grammar details related to NS model and update the NS model. - Wrap up

Added a time slot for Network service VL Discussion. WAN service IM/DM Proposal (Zhuoyao)
WAN (Service Component) IM
Need clarifications on relationship with ONF CIM and/or TAPI model.WAN (Service Component) DM
Need clarificationson relationship with parallel TOSCA Data Modeling practice at ONF and avoid collision if possible (e.g. in terms of naming conventions)
- Network Service Discussion
- NetworkService Model Diagram (Maopeng)
Add reference to IFA 014 2.4.1 when appropriate. Need sync with SDC/VF-C for implementation plan in R2. - Network service VL Discussion (Nagesha)
Very briefly done due to time limit. Will provide wiki page contribution and kick off further discussion.

No comments received and proceeded with the proposed agenda. Service IM recap and update(Kevin)
No update made to the clean version as agreed back in December F2F. (Kevin)
Concerns raised about potential alignment conflicts with MEF service models, which would be discussed further in March F2F. (Mehmet and others)- Service DM proposal (Maopeng)
It is clarified that both network service and wan service are derived from service component. The network service as it currently represented is a simplified subset of Network Service as define by ETSI NFV, without VNFFG or Deployment Flavour etc. (Maopeng)
UML class diagram for corresponding IM design was requested to be added. (Andy)
More sophisticated design for virtual link might need to be considered for some service provider scenario, contribution to be expected in later discussion. (Thinh) - WAN service modeling proposal (Zhuoyao)
It is recognized as a good approach to proceed, suggest to add consideration for covering both intra-DC connectivity and inter-DC connectivity for underlay. (Gil & Andy) - Wrap up
All participants are encouraged to leave their comments to the wiki discussion pages for further discussion and better tracking.
