DRAFT PROPOSAL FOR COMMENTS
...
- This project will deliver a unified set of VNF Guidelines and VNF Requirements.
- The VNF Guidelines and VNF Requirements must be versioned to enable evolution based on operational experience
- The VNF Guidelines and VNF Requirements will support the ONAP Architecture Principles.
- Update the VNF Requirements as prototype RFP text for the ONAP/Beijing release including:
- Hardware Platform Awareness (HPA) Requirements
- HEAT/TOSCA Information Model updates
- Update the VNF Guidelines as for the ONAP/Beijing release
- Update the VNF Requirements as prototype RFP text for the ONAP/Beijing release including:
- Identify a list of features and functionality will be developed.
- The VNF Guidelines and Requirements will support the Release 1 Use Cases.
- Use cases focused on VNF Requirements may be developed in this project, and they will need to be aligned with the ETE Platform use cases.
- Document the VNF Provider Guidelines for VNF Scaleout Use Case for the ONAP/Beijing release
- VNF Guidelines and Requirements are to be refined beyond prototype text (e.g. through EPIC statements, use cases) to deliver test cases and test procedures for us in VNF onboarding & validation. VNF Requirement level use cases to be aligned with ETE platform use cases
- Document the VNF Test Case Descriptions for VNF Package testing for the ONAP/Beijing release
- Identify what is in or out of scope. During the development phase, it helps reduce discussion.
- VNF Guidelines may be forward looking, or include best practices in VNF design and VNF lifecycle processes.
- VNF Requirements from ONAP APIs should be linked to the ONAP Release
- VNF Requirements may include:
- expected operational characteristics ( e.g. security, resilience, upgradeability)
- conditional requirements (e.g. When configured for deployment on High Availability Network Cloud Infrastructure, the VNF Shall …)
- Tool chain improvements
- Develop requirements structure/ metadata to support better linkage / tracking with other ONAP projects
- Develop templates for VNFs to demonstrate VNF Requirements conformance

The VNF Requirements developed by this project are applicable to the VNFs identified in the TSC E2E use cases.
- a VNF Provider (developer) using VNF Requirements in designing, testing, and certifying a VNF for use on ONAP
- a Service Provider using VNF Requirements as prototype text for RFPs to acquire VNFs to run in an ONAP context see VNFRQTS-16
- VNF Validation Project uses VNF Test Descriptions developed by this project to implement VNF testing for validation purposes.
...
- A VNF Guidelines document summarizing VNF provider oriented deliverables and providing informative, forward lookiging guidance.
- A set of Integrated VNF Requirements for use as prototype RFP text.
- VNF Test Descriptions for use by VNF Validation project, traceable from the VNF Requirments
- VNF Use Case - VNF Provider Guidelines for VNF Scale Out Use Case

This section is used to document a limitation on a functionality or platform support. We are currently aware of this limitation and it will be delivered in a future Release.
List identified release gaps (if any), and its impact.
| Gaps identified | Impact |
|---|---|
| VNF Requirments Requirements linkage to testing | VNF Requirements are current provided for RFP purposes, but the linkage to testing and validation of those requirments is not yet in place This release provides initial generic test plan descriptions for testing of VNFs based on the VNF Package. It does not provide test descriptions for design time or run time functional testing of VNFs. The testing linkage is also costrained by the scope of the VNF Information model in the VNF Package and the relationships identified between that information model and the VNF requirements. |
Known Defects and Issues
...
| Hardware / infrastructure requirements | The Amsterdam release requirments had a placeholder (Chapter 6) for VNF requirements associated with the hardwrae executuion environment. Additional requirments are expected in this area from the Multi-VIM project, and perhaps the PNF related features. |
| HEAT/TOSCA requirements | The Amsterdam release requirments has text on HEAT and TOSCA requirmenst but not numbered requirments text. This is expected to be improved as part of the Beijing release work. |
Known Defects and Issues
Provide a link toward the list of all known project bugs.
...
| Risk identified | Mitigation Plan | Contingency Plan |
|---|---|---|
| ONAP supporting multiple onboarding formats | work with VNF SDK, VVP and SDC to minimize the risk. | Document the desired direction in the forward looking VNF Guidelines |
