Array of key-value pair requirements on the memory for the VDU. It specifies the memory allocation to be cognisant of the relevant process/core allocation. The cardinality can be 0 during the allocation request, if no particular value is requested. The VirtualCpuData information element supports the specification of requirements related to virtual CPU(s) of a virtual compute resource. CPU architecture type. Examples are x86, ARM. The cardinality can be 0 during the allocation request, if no particular CPU architecture type is requested. Number of virtual CPUs. Minimum virtual CPU clock rate (e.g. in MHz). The cardinality can be 0 during the allocation request, if no particular value is requested. The CPU core oversubscription policy e.g. the relation of virtual CPU cores to physical CPU cores/threads. The cardinality can be 0 during the allocation request, if no particular value is requested. Array of key-value pair requirements on the Compute (CPU) for the VDU. The virtual CPU pinning configuration for the virtualised compute resource. The VirtualCpuPinningData information element supports the specification of requirements related to the virtual CPU pinning configuration of a virtual compute resource. 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). A list of rules that should be considered during the allocation of the virtual CPUs to logical CPUs in case of "static" virtualCpuPinningPolicy. This information element provides a means to define in the VNFD attributes that represent the configurable properties of a VNF. Configurable properties can be standardized as listed below (e.g. related to auto scaling, auto healing and interface configuration), or can be VNF-specific as defined by the VNF provider. For a VNF instance, the value of these properties can be queried and modified through the VNFM, using the Query VNF and Modify VNF Information operations. Modifying these values affects directly the configuration of an existing VNF instance. If a configurable property is defined in the VNFD, an initial value may be defined as well. It permits to enable (TRUE)/disable (FALSE) the auto-scaling functionality. NOTE: A cardinality of "0" indicates that configuring this present VNF property is not supported. It permits to enable (TRUE)/disable (FALSE) the auto-healing functionality. NOTE: A cardinality of "0" indicates that configuring this present VNF property is not supported. Contains information enabling access to the NFV-MANO interfaces produced by the VNFM (e.g. URIs and credentials) Contains information to enable discovery of the authorization server protecting access to VNFM interface Contains information to enable discovery of the authorization server to validate the access tokens provided by the VNFM when the VNFM accesses the VNF interfaces, if that functionality (token introspection) is supported by the authorization server. This datatype defines the VNF-specific extension and metadata attributes of the VnfInfo that are writeable via the ModifyVnfInfo operation. All additional VNF-specific attributes of VnfInfo that affect the lifecycle management of a VNF instance. For each VNF instance, these attributes are stored persistently by the VNFM and can be queried and modified through the VNFM. These attributes are intended to be consumed by the VNFM or by the lifecycle management scripts during the execution of VNF lifecycle management operations. Modifying these values has no direct effect on the VNF instance; however, modified values can be considered during subsequent VNF lifecycle management operations, which means that the modified values can indirectly affect the configuration of the VNF instance. Additional VNF-specific attributes of VnfInfo that provide metadata describing the VNF instance and that are defined by the VNF provider. See note 2. For each VNF instance, these attributes are stored persistently by the VNFM and can be queried and modified through the VNFM. These attributes are intended to provide information to functional blocks external to the VNFM and will not be used by the VNFM or the VNF lifecycle management scripts when executing lifecycle management operations. Modifying these attributes has no effect on the VNF instance. It only affects the attribute values stored by the VNFM.

Types of scripts could include bash, python, etc. Array of KVP requirements with the key as the parameter name and the value as the parameter that need to be passed as an input to the script. NOTE: The scriptInput values are passed to the scripts in addition to the parameters received in the operation invocation request or indicator value change. Specifies the virtualized resource related performance metric to be tracked by the VNFM, e.g. for auto-scaling purposes. The VNFM collects the values of performance metrics identified by this information element from the VIM(s) using one or more locally initiated PM Jobs. These values can be used as inputs to auto-scaling rules. Unique identifier of the monitoring parameter. Human readable name of the monitoring parameter. Identifies the virtualized resource performance metric. An attribute that describes the periodicity at which to collect the performance information. This information element provides a means to define additional VNF-specific attributes that represent the configurable properties of a VNFC. For a VNFC instance, the values of these properties can be queried and modified through the VNFM. Modifying these values affects directly the configuration of an existing VNFC instance. It provides VNFC configurable properties that can be modified using the ModifyVnfInfo operation. Describes the type of VNIC to which a CP attaches. The ScaleInfo information element represents a scale level for a particular scaling aspect. Reference to the scaling aspect. The scale level, greater than or equal to 0 Defines the CPU pinning policy. Describes VNF lifecycle event(s) or an external stimulus detected on a VNFM reference point. Describes the source of the indicator. Specifies the periodicity at which the producer will collect performance information. Note: at the end of each reportingPeriod, the producer will inform the consumer about availability of the performance data collected for each completed collection period during this reportingPeriod. While the exact definition of the types for collectionPeriod and reportingPeriod is left for further specification, it is recommended that the reportingPeriod be equal or a multiple of the collectionPeriod. In the latter case, the performance data for the collection periods within one reporting period would be reported together.
