- Vendor neutrality
- Consistency of hardware platform capability and/or capability requirements specification
- The specification is use case neutral
- The specification follows the format defined by the ETSI NFV Hardware Platform Capability Registry
- The specification is VNFD specification and/or data model neutralFor TOSCA described VNFs, the specification is compliant with the ETSI NFV SOL SOL001 data model specification
- There is full equivalence between manual, declarative and imperative means of specification
- Consistency of VNF orchestration outcomes
- The outcome of VNF instantiation is consistent regardless of how a given VNF was instantiated
- The outcome of VNF scaling is consistent regardless of how a given VNF was scaled
- The outcome of VNF change management actions is consistent regardless of how VNF change management was performed
- Extensibility/Pluggability
- New hardware platform capabilities can be introduced without incurring changes to ONAP components
- Specification of existing platform capabilities can be modified or extended without incurring changes to ONAP components
- Hardware platform capabilities can be removed without incurring changes to ONAP components
- OOF homing and placement constraints, based on hardware platform capability requirements, can be added, modified or removed without incurring changes to ONAP components
