Background
Assumptions & Decisions
- Specification based on tuples
- For R2, only TOSCA based VNFD will be supported
- Will need to add hardware platform capability requirements to the VNFD TOSCA template
- May need to add migration tools to convert from HEAT to TOSCA as part of th VNF SDK
- For R2, VNFD must be based on R2 ONAP common information model
- Hardware platform capability requirements shall be VNFD format and template grammar agnostic.
- For TOSCA based VNFDs, will specify hardware platform capability requirements as a single TOSCA capability with a string value
- Will need utilities to parse and search the string
Work Items
| Assumption/Decision | ||
|---|---|---|
| 1 | Hardware platform capability requirements shall be specified as a VNFD encoding agnostic format, order to accommodate alternative VNFD representations and encoding formats, such as YANG, HEAT, etc... The requirements shall be specified as a comma separated list of of tuples, as defined on the HPA Requirement & Capability Specification page. | |
| 2 | Hardware platform capability requirement specificaiton shall be limited to TOSCA grammar based VNFD templates, encoded using OASIS TOSCA YAML grammar and based on the ONAP VNFD information model definition for R2. | |
| 3 | For TOSCA grammar based VNFDs, hardware platform capability requirements shall be specified using one or more TOSCA capability clauses, with opaque string values containing comma separated tuples, as described above. | |
| 4 | If use of alternatively encoded VNF descriptors is desired, additional migration tools shall be provided as part of the VNF SDK. | |
| 5 | HEAT to TOSCA migration tools shall be provided for already existing VNFs certified for use with ECOMP. |
