# Copyright (c) ETSI 2017. # https://forge.etsi.org/etsi-forge-copyright-notice.txt definitions: GrantRequest: description: > This type represents a grant request. It shall comply with the provisions defined in table 9.5.2.2-1. NOTE 1: The VNF LCM operations CreateVnfIdentifier, DeleteVnfIdentifier, QueryVnf and ModifyVnfInformation can be executed by the VNFM without requesting granting. NOTE 2: If the granting request is for InstantiateVNF, either instantiationLevel or addResources shall be present. NOTE 3: The NFVO will assume that the VNFM will be responsible to both allocate and release the temporary resource during the runtime of the LCM operation. This means, the resource can be allocated and consumed after the "start" notification for the LCM operation is sent by the VNFM, and the resource will be released before the "result" notification of the VNF LCM operation is sent by the VNFM. NOTE 4: The affinity/anti-affinity rules defined in the VNFD and the placement constraints in the GrantVnfLifecycleOperation as defined in this clause should be conflict-free. In case of conflicts, the placement constraints in the GrantVnfLifecycleOperation shall take precedence. NOTE 5: Passing constraints allows the VNFM or the lifecycle management scripts to influence resource placement decisions by the NFVO to ensure VNF properties such as performance or fault tolerance. NOTE 6: If fallbackBestEffort is present in placement constraints and set to "true", the NFVO shall process the Affinity/AntiAffinity constraint in a best effort manner, in which case, if specified resources cannot be allocated based on specified placement constraint, the NFVO looks for an alternate best effort placement for the specified resources to be granted. In the best effort anti-affinity case, the resources are expected to be spread optimally over all available instances of scope (e.g. zones), and in the best effort affinity case, they are expected to be distributed optimally over fewer possible instances of scope. type: object required: - vnfInstanceId - vnfLcmOpOccId - vnfdId - operation - isAutomaticInvocation - _links properties: vnfInstanceId: description: > Identifier of the VNF instance which this grant request is related to.

NOTE 1: This interface allows to signal the use of multiple VIMs per VNF. However, due to the partial support of this feature in the present release, it is recommended in the present document that the number of entries in the "vims" attribute in the Grant is not greater than 1. NOTE 2: Void. NOTE 3: The Grant response allows the NFVO to pass to the VNFM VIM assets related to the VNF package that is identified by the vnfdId attribute in the corresponding Grant request. The NFVO may send in each Grant response the full set of VIM assets related to the VNF package defined by the vnfdId in the related Grant request, but shall send this information if the vnfdId in the related Grant request differs from the vnfdId passed in the previous Grant request, or if the Grant response is related to an InstantiateVnf operation. The set of VIM assets shall not change between subsequent Grant responses if the vnfdId has not changed. During each LCM operation occurrence, the VIM assets that relate to the VNF package identified by the current value of the vnfdId attribute in the "VnfInstance" structure shall be used by the VNFM for newly created resources. If the VNF package identifier of the VNF instance has been updated, VIM assets that relate to the previously-used VNF package(s), and that were communicated in previous Grant responses, apply to existing resources. NOTE 4: The indication of externally-managed internal VLs is needed in case networks have been pre-configured for use with certain VNFs, for instance to ensure that these networks have certain properties such as security or acceleration features, or to address particular network topologies. The present document assumes that externally-managed internal VLs are managed by the NFVO and created towards the VIM. NOTE 5: For any VNF lifecycle management operation request that allows to pass "extVirtualLinks" and/or "extManagedVirtualLinks" parameters, such as InstantiateVnf, ChangeVnfFlavour, ChangeExtVnfConnectivity or ChangeCurrentVnfPackage, the NFVO may provide the "extVirtualLinks" and/or "extManagedVirtualLinks" attributes in the Grant to override the values passed in these parameters previously in the associated VNF lifecycle management request, if the lifecycle management request has originated from the NFVO itself. The NFVO shall not provide the "extVirtualLinks" and/or "extManagedVirtualLinks" attributes in the Grant otherwise. NOTE 6: The NFVO shall set the value of the attribute by copying the value from the associated GrantRequest. NOTE 7: In case of granting an InstantiateVnf request that has originated from the NFVO and that did not contain the "extVirtualLinks" attribute, this attribute shall be set by the NFVO. Further in case of granting an InstantiateVnf request that has originated from the NFVO and that did not contain the "extManagedVirtualLinks" attribute, this attribute shall be set by the NFVO if there is the need to provide information about externally-managed virtual links. type: object required: - id - vnfInstanceId - vnfLcmOpOccId - _links properties: id: description: > Identifier of the grant. $ref: "../../../definitions/SOL002SOL003_def.yaml#/definitions/Identifier" vnfInstanceId: description: > Identifier of the related VNF instance.
