NSD Requirements:
1, VFC project requirement
- VFC project implement ETSI NFVO, which needs to consume the NSD.
- VFC needs to expose NFVO northbound SOL005 interfaces to SO or OSS/BSS/3GPP Management System
JIRA : VFC-635/VFC-648
2, NSD vs ServiceD differences:
Service Descriptor in SDC R3: Service composites many resources in the SDC, including SDC AID resources(vf, extVL, AllottedResource) and R2+ resources.
NSD in VFC: NSD composites VNFD, PNFD, and NSVirtualLink, nested NSD, etc, ETSI NFV resources.
NSD requires to do some limitation in NFV resources composition, not all the SDC resources and substitution_mappings to NS TOSCA node
