VnfInstance:
description: >
This type represents a VNF instance.
* NOTE: Clause B.3.2 provides examples illustrating the relationship among the different run-time
data types (CP, VL and link ports) used to represent the connectivity of a VNF.
* NOTE 1: Modifying the value of this attribute shall not be performed when conflicts exist
between the previous and the newly referred VNF package, i.e. when the new VNFD is
changed with respect to the previous VNFD in other aspects than merely referencing
to other VNF software images. In order to avoid misalignment of the VnfInstance with
the current VNF's on-boarded VNF package, the values of attributes in the VnfInstance
that have corresponding attributes in the VNFD shall be kept in sync with the values in the VNFD.
* NOTE 2: ETSI GS NFV-SOL 001 specifies the structure and format of the VNFD based on TOSCA specifications.
* NOTE 3: VNF configurable properties are sometimes also referred to as configuration parameters
applicable to a VNF. Some of these are set prior to instantiation and cannot be modified
if the VNF is instantiated, some are set prior to instantiation (are part of initial configuration)
and can be modified later, and others can be set only after instantiation.
The applicability of certain configuration may depend on the VNF and the required operation of
the VNF at a certain point in time.
* NOTE 4: Upon creation of the VnfInstance structure, the VNFM shall create and initialize all child
attributes of "vnfConfigurableProperties", "metadata" and "extensions" that were declared
in the VNFD with a defined initial value. The defined initial values can be declared in the VNFD,
and/or, in case of "metadata", obtained from the "CreateVnfRequest" structure. Child attributes of
"vnfConfigurableProperties", "metadata" and "extensions" that have no defined initial value shall
not be created, in order to be consistent with the semantics of the JSON Merge Patch method
(see IETF RFC 7396) that interprets null values as deletion request.
* NOTE 5: It is possible to have several ExtManagedVirtualLinkInfo for the same VNF internal VL in case
of a multi-site VNF spanning several VIMs. The set of ExtManagedVirtualLinkInfo corresponding
to the same VNF internal VL shall indicate so by referencing to the same VnfVirtualLinkDesc
and externally-managed multi-site VL instance (refer to clause 5.5.3.5).
* NOTE 6: Even though externally-managed internal VLs are also used for VNF-internal connectivity,
they shall not be listed in the "vnfVirtualLinkResourceInfo" attribute as this would be redundant.

vnfConfigurableProperties:
description: >
Additional VNF-specific attributes that provide the current values
of the configurable properties of the VNF instance.
These attributes represent values that are stored persistently in
the VnfInstance structure and that correspond to configuration
parameters of the VNF instance.
Modifying these attributes affects the configuration of the VNF
instance either directly (if the VNF instance is in INSTANTIATED
state at the time of the modification) or as part of the subsequent
VNF instantiation operation (if the VNF instance is in NOT_INSTANTIATED
state at the time of the modification).
Configurable properties referred in these attributes shall be declared
in the VNFD.
The declaration of configurable properties in the VNFD can optionally
contain the specification of initial values. See note 2, note 3 and note 4. The VNFM
shall reject requests to write configurable properties that are not declared in the
VNFD with a "422 Unprocessable Content" error response as defined in clause 6.4 of ETSI GS NFV SOL 013.
These configurable properties include the following standard attributes,
which are declared in the VNFD if auto-scaling and/or auto-healing are
supported by the VNF:
- isAutoscaleEnabled: If present, the VNF supports auto-scaling. If set
to true, auto-scaling is currently enabled. If set to false, auto-scaling
is currently disabled.
- isAutohealEnabled: If present, the VNF supports auto-healing. If set
to true, auto-healing is currently enabled. If set to false, auto-healing
is currently disabled.
These configurable properties can be initialized with default values from the VNFD (see note 4).
Configurable properties can be modified with values passed in the request structures of certain
LCM operations, such as the InstantiateVnfRequest structure.
Further, these configurable properties can be created, modified or deleted with the PATCH method.
In addition, the provisions in clause 5.7 shall apply.

All extensions that are allowed for the VNF are declared in the VNFD. The declaration of an

requests to write extension attributes that are not declared in the VNFD with a "422 Unprocessable

Modifying the values of these attributes has no direct effect on the VNF instance; however, the
modified attribute 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.
These attributes can be initialized with default values from the VNFD (see note 4).

vnfcInfoModifications:
description: >
Modifications of certain entries in the "vnfcInfo" attribute array in the
"instantiatedVnfInfo" attribute of "VnfInstance" to be used as "newList" as defined below this table.
The following provisions shall apply when modifying an attribute that is an array of objects of type
"VnfcInfo" by supplying an array of objects of type "VnfcInfoModifications".
Assumptions:
1) "oldList" is the "VnfcInfo" array to be modified and "newList" is the "VnfcInfoModifications"
array that contains the changes.
2) "oldEntry" is an entry in "oldList" and "newEntry" is an entry in "newList".
3) A "newEntry" has a "corresponding entry" if there exists an "oldEntry" that has the same content
of the "id" attribute as the "newEntry"; a "newEntry" has no corresponding entry if no such "oldEntry" exists.
4) In any array of "VnfcInfo" resp. "VnfcInfoModifications" structures, the content of "id" is unique
(i.e. there are no two entries with the same content of "id").
Provisions:
1) For each "newEntry" in "newList" that has no corresponding entry in "oldList",
the "oldList" array shall be modified by adding that "newEntry".
2) For each "newEntry" in "newList" that has a corresponding "oldEntry" in "oldList",
the value of "oldEntry" shall be updated with the content of "newEntry" as specified for
the data type of "newEntry (refer to clause 5.5.3.24 for the data type "VnfcInfoModifications").
