Class Name | Attribute Name | Type | Multiplicity | Description | Applied Stereotypes | Category | Rationale | ETSI reference Discussion | IFA + SOL Recommendation | IFA Contribution | SOL Contribution | ONAP Recommendation |
Vnfd | vnfmInfo | String | 0..* (IFA has 1..*) | Identifies VNFM(s) compatible with the VNF described in this version of the VNFD. Using the name of micro-service of the vnfm drive. For vendor specific VNFM, the value composes of "vendorname" and "vnfmdriver", e.g. "mycompanyvnfmdriver"; for generic VNFM, the value is "gvnfmdriver". | OpenModelAttribute
support: MANDATORY | value specified cardinality change | Value is specified according to the usage in VFC project. Lower cardinality is changed to 0 because not all VNFs in ONAP need to be managed by VNFMs, SO/APPC could also serve the similar functionality. | NFVIFA(19)000200r1 | Multiplicity: 0.*: Keep current IFA011. ONAP can use this attribute for indicating either SO/APPC.
Attribute Value: SOL001 is already defined with a pattern. | No action required | No action required | It is proposed not to change Multiplicity. Not to update the description.
|
Vnfd | localizationLanguage | String | 0..* | Information about localization languages of the VNF (includes e.g. strings in the VNFD). NOTE: This allows to provide one or more localization languages to support selecting a specific localization language at VNF instantiation time. The value refer to ISO936 https://www.iso.org/iso-639-language-codes.html . | OpenModelAttribute
support: MANDATORY | type and value specified | Value is specified according to the usage in VFC project. | NFVIFA(19)000200r1 | SOL001 v2.5.1 defines as string and reference to RFC5646 which reference to ISO639. | No action required | No action required | Typo in description (ISO639).
Recommends to align with reference used in SOL (RFC5646 which reference to ISO639). |
Vnfd | defaultLocalizationLanguage | String | 0..1 | Default localization language that is instantiated if no information about selected localization language is available. The value refer to ISO936 https://www.iso.org/iso-639-language-codes.html . | OpenModelAttribute
condition: Shall be present if "localizationLanguage" is present and shall be absent otherwise. | type and value specified | Value is specified according to the usage in VFC project. | NFVIFA(19)000200r1 | SOL001 v2.5.1 defines as string and reference to RFC5646 which reference to ISO639.

support: MANDATORY | new attribute |
| The use cases presented in 215r3 are valid use cases and are similar to ONAP use case.
215r3 proposes 2 solutions. Further discussions required. Start with examples based on one of the solutions.
| Work in progress | Work in progress | We acknowledge the need for supporting shared IP addresses (VIPs).
Please refer to NFVIFA(19)000288r1 which contains the currently identified use cases. ONAP is requested to comment/confirm the use cases. | |
Vnfd | modifiableAttributes | VnfInfoModifiableAttributes | 1 (IFA has 0..1) | Describes the modifiable attributes of the VNF. | OpenModelAttribute
support: MANDATORY | cardinality change |
| NFVIFA(19)000200r1 | modifiableAttributes defines the VNF-specific extension and metadata attributes of the VnfInfo. These are optional attributes and depending on the design of VNF. No change is needed. | No action required | No action required | It is proposed not to change Multiplicity. |
Vnfd | logo | String | 0..1 | File path of the vendor specified logo. | OpenModelAttribute isInvariant: false support: MANDATORY | new attribute |
| NFVIFA(19)000200r1 | What is the rational of having logo as part of the VNFD as an attribute? Perhaps, it should be part of the VNF Package information.
Not important for modelling of VNFD. Might have impacts in SOL004, it has flexibility to include details specific to VNF by the VNF vendor. Can this be part of Non-MANO artefact? Not needed in the VNFD. | No action required | No action required | Not recommended to be part of VNFD.
In ETSI, there is no requirement for including Logo or Guide in the Descriptor.
Non-MANO artifacts can be used already for storing this type of data. This can be a ONAP-specific artefact or generic-artifact.
|
Vnfd | guide | String | 0..1 | UUID of the vendor guide/documentation which is attached to VNF and can be downloaded from the model. | OpenModelAttribute isInvariant: false support: MANDATORY | new attribute |
| NFVIFA(19)000200r1 | Not the benefit of having guide as part of the VNFD as an attribute. Perhaps, it can be part of the VNF Package information. If included in package, any change in guide will need a new package.
| No action required | No action required | Not recommended to be part of VNFD.
What is the rational of having a guide as part of the VNFD as an attribute.
Having a guide or logo in the VNFD, a new VNFD and VNF Package will be required when there is a small change to the guide or logo.
In ETSI NFV, there is no requirement for including Logo or Guide in the Descriptor.
Non-MANO artifacts can be used already for storing this type of data. This can be a ONAP-specific artefact or generic-artifact.

Vdu | nfviConstraint | KeyValuePair | 0..* | Describes constraints on the NFVI for the VNFC instance(s) created from this Vdu. For example, aspects of a secure hosting environment for the VNFC instance that involve additional entities or processes. NOTE: These are constraints other than stipulating that a VNFC instance has access to a certain resource, as a prerequisite to instantiation. The attributes virtualComputeDesc and virtualStorageDesc define the resources required for instantiation of the VNFC instance. The "key/name" includes "AvailabilityZone" and "HostAggregates". | OpenModelAttribute
support: MANDATORY | type specified | Openstack has the concepts "availability zone" and "host aggregates" by which the operator could specify (or constrain) the deployment location of the VM (VNFC instance). It's proposed to have these two attributes defined in the VNFD as input parameters (with default values defined if necessary). | 1. Agree to type change proposed by ONAP. Change the type to “KeyValuePair” in IFA011 if okay from SOL WG point of view.
2. The proposed changes in the description would require further discussion. The use case that a “default value is given for availability zone or host aggregate” is unclear. In principle, at design time, it is not possible to know the value/names of the availability zones or host aggregates, therefore, it is not clear what value can be put there. Also, requirements on affinities (which is a use case for the zones), is already covered by the localAffinityOrAntiAffinityRule. The run-time signaling of placement constraints is supported on the interfaces, such as “VnfLocationConstraint” in the IFA013 (clause 8.3.4.4), the “placementConstraint” and “zoneGroup” in the granting process in the IFA007 (clause 6.3.2).
Based on this it is recommended not to change the description and request further clarification from ONAP | NFVSOL(19)000162r1 (pending approval) | Thanks for indicating the change of type. We will update the datatype in IFA011.
The datatype in SOL001 is changed to map of strings to support KeyValuePair.

Vdu | injectFiles | String | 0..* | Describes the information (e.g. URL) about the scripts, config drive metadata, etc. which can be used during Vdu booting process. | OpenModelAttribute
| new attribute | There are two ways to inject data into VM instance during instantiation process: 1) using config drive to provide such information (covered by the bootData attribute in the VNFD); 2) using an injection file. It's proposed to also support this way of providing additional data to the VM instance. Note: file injection is deprecated in OpenStack Queen version | File injection is deprecated in OpenStack Queen version, since file injection is insecure, not very user friendly, and there are alternatives:
Therefore, file injection should not be introduced in IFA011.

SwImageDesc | version | String | 1 | The version of this software image. | OpenModelAttribute
support: MANDATORY | question | "vnfSoftwareVersion" and "vnfdVersion" attributes have type "Version", while this attribute has type "String", should they be aligned? i.e., change "String" into "Version"? | SOL001 is consistently using type “String” for all “version” attributes, so it would be okay for IFA011 to keep using “String” type.
However, it would make sense to align the use of “Version” vs. “String” in IFA011. - VNFD uses “Version” - SwIMageDesc uses “String” - RequestedAdditionalCapabilityData uses “String”
Other IFA specifications use type “Version”, e.g. IFA014 consistently uses “Version”.
Also, the IFA015 information model is introducing a primitive type “Version”.
It is proposed to change to type from "string" to “Version” in IFA011 to be consistent with IFA014 & IFA015.
It is up to the SOL specification work to specify what data type / format should be used for the primitive type “Version”, and IFA does not have to mandate the type “String”. | No action required | Thanks for indicating the change of type. We will update the datatype for version in IFA011.

Recommendation to IFA to change the QoS class to NSQoS class in IFA014. (consistency between IFA014 & IFA015). This change has no impact to SOL001 but need to check SOL006.
It is not mandatory to rename QoS for IFA011 as the SOL001 uses the same name.

The requirement of ONAP to support KeyValuePair type for scriptInput already supported by SOL001. | No action required | No action required | Recommendation to reference the datatype from example in chapter 6.7.1 in SOL001. | |
MonitoringParameter | collectionPeriod | Enum (CollectionPeriod) but with no enumeration literals defined | 0..1 | An attribute that describes the recommended periodicity at which to collect the performance information. VNFM determines if this parameter is considered. The vendor may provide this information as a guidance for creating PmJobs if needed. NOTE: The MANO or NFVI may not support the recommended collectionPeriod based on their functionalities, and can reject the requests based on the recommended collectionPeriod in this case. | OpenModelAttribute
support: MANDATORY | type specified |
| The ONAP proposal for change of Type to ENUM is not possible as different metrics can have different values. scalar-unit.time is defined in SOL001 for collectionPeriod. | No action required | No action required | ETSI recommendation is to use scalar-unit.time in ONAP information model and data model. | |
