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. |

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. |

Possible option tagging in the ExtManagedVirtualLink in the VirtualLinkProfile. |
ONAP has updated the VNFD information model according to IFA011 v2.5.1, (Updated V2.5.1 VNFD Model), in which cidr, allocationPools, etc. are already moved into the L3ProtocolData. Regarding segmentationId, it's acceptable to put it into L2ProtocolData. It's suggested to make this addition in the next version of IFA011. Regarding physicalNetwork, it's acceptable to generalize the name. However, the possible option is not sufficient. There could be two different use cases for the provider network: 1) use the provider network directly as an implementation of a virtual link, the possible option could work; 2) still need to create a virtual link, the provider network is a constraint of the creation, indicates the VL needs to be created on top of the selected provider network, in this case, the VL is still managed by the VNFM, so the ExtManagedVirtualLink may not be the proper place to model it. It's expected that ETSI could discuss more and come up with a concrete solution. | ||||

question
IFA015 seems to have defined "VnfQoS" as the type. Should IFA011/014 follow the same pattern, i.e., define "VnfQoS" and "NsQoS" separately?
NFVIFA(19)000230r1
QoS in Vnf template is same as the QoS in common template of IFA015.
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.

000230r1 | QoS in Vnf template is same as the QoS in common template of IFA015. 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. | IFA014 CR for renaming qos to NsQos | SOL006 confirmation | Thanks for indicating the change. We will update IFA014 with IFA015 alignment. This alignment has no impact to SOL001. | |

question | IFA015 has the cardinality defined as 1, is it a mistake? | Agree to question from ONAP and change IFA015. It is proposed to create an entry in the ETSI bug tracker to change cardinality in IFA015. | IFA015 Bug tracker number | No action required | Thanks for indicating the change. We will update the cardinality in IFA015. This alignment has no impact to SOL001. | ||
VirtualCpuPinningData | virtualCpuPinningPolicy | Enum |
0..1 |
The policy can take values of "static" |
or "dynamic". In case of "static" the virtual CPU cores are requested to be allocated to logical CPU cores according to the rules defined in virtualCpuPinningRules. In case of "dynamic" the allocation of virtual CPU cores to logical CPU cores is decided by the VIM. (e.g.: SMT (Simultaneous Multi-Threading) requirements). | OpenModelAttribute

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
