Support for Nested/Hierarchical ETSI SOL001  compliant Network Service Descriptor  (ETSI Package Management)

Enhancement to AR-002-R7-052020 & AR-003-R7-052020

Enable an ONAP user to Onboard or Design, Catalog and Distribute an ETSI SOL007 v2.7.1 compliant (Link to ETSI SOL007 v2.7.1)  Network Service Descriptor package including an ETSI version 2.7.1 SOL001 Network Service Descriptor (NSD) that references other Network Service Descriptors for deployment as an ONAP Service or deployment using an ETSI compliant NFVO.

• Support for Designing an ETSI NFV SOL001 v2.7.1 compliant Nested/Hierarchical Network Service Descriptor (NSD) (Link to ETSI SOL001 v2.7.1) that references other NSD using SDC

• Support for Cataloging, Preserving and Distributing the NSD in an ETSI NFV SOL007 v2.7.1  package

• Support for mapping the ETSI v2.7.1 SOL001 v2.7.1 Nested/Hierarchical Network Service Descriptor into SDC AID Data Model

• Support for deploying a service that contains an ETSI SOL001 v2.7.1 compliant Nested/Hierarchical Network Service using an ONAP internal NFVO

• Support for deploying a service that contains an ETSI SOL001 v2.7.1 compliant Nested/Hierarchical  Network Service using an external NFVO

New component capabilities for Guilin, i.e. the functional enhancements, if applicable

1. Enables an ONAP user to use SDC to design an ETSI NFV SOL001 v2.7.1 compliant Nested/Hierarchical Network Service that can be packaged into an ETSI NFV SOL007 v2.7.1 compliant package

2. Enables those SOL007 packages to be cataloged and transformed into an ONAP Service that can be deployed directly by SO using the SOL005 NFVO Adapter or directly deployed via VF-C or an external NFVO.

3. Enables the ETSI NFV Nested/Hierarchical Network Service package to be distributed as an ONAP Service CSAR from SDC to other ONAP components (A&AI, DCAE, SO, ETSI Catalog, ...)

4. Enables the Nested/Hierarchical Network Service instances to be  Inventoried, Configured, Monitored and LifeCycle Managed
