Context:

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.
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

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)
