ONAP R3 Modeling High Level Requirements

Resource

VNFD

ONAP Resource Data Model for Design Time?

-Agreement that the VNF Descriptor model for On-Boarding and the Internal ONAP models are distinct. (note: an internal model may be used as one of the on-boarding options)
•For R3 the VNF Descriptor On-Boarding options include: HEAT and TOSCA (SOL004 v2.5.1 VNF Package, ONAP R3 Resource DM) (see note)
-Acknowledgement that there are two Internal ONAP VNF Descriptor Data Models that, for R3, will evolve wherever possible in a coordinated way in support of the Casablanca Use Cases
•ONAP R2+ Design-Time Resource DM clean version enhancements for VoLTE, CCVPN, vCPE (stretch goal)
•ONAP SDC TOSCA AID enhancements for vCPE
-Engage impacted ONAP Components to understand the VNF Descriptor aspects of these two Internal ONAP R3 Resource Data Models are applied
•Document ONAP R3 VNFD on-boarding and internal models roadmap with all ONAP components stakeholders

 Network Service

(modeling subcommitee  DM approve firstly)

Context:

1. In R2 VoLTE case, SDC support VoLTE service composed of IMS/EPC service as VNF. IMS/EPC Service can be composed of VNF, and VLD resources.
   In service layer, VOLTE service should focus on the IMS/EPC/... service composition, not coupled with the specific IMS/EPC/... resource composition. In the different scenes, IMS service can be implemented in different resources layer, for example, small capacity or large capacity, VNF in one DC or VNF on multiDC, even all PNFs or PNFs/VNFs, etc The multiple resource composition should not affected the service design. So network service is introduced, which is in charge of different IMS resource composition and let the service design not coupled with the resource composition design in detail.

2. TMF support service and resource, and also in resource layer, there is resource composite. and Network service from ETSI can be mapping to the resource composite

3. model subcommittee progress:

Network service is agreed in resource IM group. Networkservice IM Network service Descriptor has been discussed in DM group. Networkservice DM

4. SDC progress

org.openecomp.resource.vfc.NSD has been imported in ONAP catalog in R2 https://gerrit.onap.org/r/gitweb?p=sdc.git;a=tree;f=catalog-be/src/main/resources/import/tosca/nfv-types/NSD;h=bf5cabb52dc41025f4708c7c095e304196e7e6a6;hb=refs/heads/master

SDC functionality does not support NSD yet in R2

SDC requiremnets in R3:

1. SDC design UI, catalog(FE,BE,Database, API) shall support NS and related package based on R2 link

2. In resource design, NS descriptor shall be composed of VNFD, and VLD at least to support VoLTE based on R2 resources

3. In service design, service descriptor could be composed of the NSD.

4. NS descriptor shall refinement to support R3 NS DM Proposal( Stretch goal)
