16 VNF On-boarding and package management
17 --------------------------------------
22 The ONAP Design Time Framework provides the ability to design NFV
23 resources including VNFs, Services, and products. The VNF provider must
24 provide VNF packages that include a rich set of recipes, management and
25 functional interfaces, policies, configuration parameters, and
26 infrastructure requirements that can be utilized by the ONAP Design
27 module to onboard and catalog these resources. Initially this
28 information may be provided in documents, but in the near future a
29 method will be developed to automate as much of the transfer of data as
30 possible to satisfy its long term requirements.
32 The current VNF Package Requirement is based on a subset of the
33 Requirements contained in the ETSI Document: ETSI GS NFV-MAN 001 v1.1.1
34 and GS NFV IFA011 V0.3.0 (2015-10) - Network Functions Virtualization
35 (NFV), Management and Orchestration, VNF Packaging Specification.

596 for putting the licenses into use and managing the full lifecycle of
597 the licenses. The details of this license model are described in
598 Tables C1 to C8 in the Appendix.
600 Note: License metadata support in ONAP is not currently available
601 and planned for 1Q 2018.
