**3.2.1 Request**
+-----------------+------------+-------------+-----------+----------------------------------+
| Parameter | Qualifier | Cardinality | Content | Description |
+=================+============+=============+===========+==================================+
| terminationType | M | 1 | Enum | Signals whether forceful or |
| | | | | graceful termination is |
| | | | | requested. |
| | | | | In case of forceful termination, |
| | | | | the VNF is shut down |
| | | | | immediately, and resources are |
| | | | | released. Note that if the VNF |
| | | | | is still in service, this may |
| | | | | adversely impact network |
| | | | | service, and therefore, operator |
| | | | | policies apply to determine if |
| | | | | forceful termination is allowed |
| | | | | in the particular situation. |
| | | | | |
| | | | | In case of graceful termination, |
| | | | | the VNFM first arranges to take |
| | | | | the VNF out of service (by |
| | | | | means out of scope of the |
| | | | | present specification, e.g. |
| | | | | involving interaction with EM, |
| | | | | if required). Once this was |
| | | | | successful, or after a timeout, |
| | | | | the VNFM shuts down the VNF |
| | | | | and releases the resources. |
+-----------------+------------+-------------+-----------+----------------------------------+
| graceful | M | 0..1 | Time | The time interval (second) to |
| Termination | | | Duration | wait for the VNF to be taken out |
| Timeout | | | | of service during graceful |
| | | | | termination, before shutting |
| | | | | down the VNF and releasing the |
| | | | | resources. |
| | | | | If not given, it is expected |
| | | | | that the VNFM waits for the |
| | | | | successful taking out of service |
| | | | | of the VNF, no matter how long |
| | | | | it takes, before shutting down |
| | | | | the VNF and releasing the |
| | | | | resources (see note). |
| | | | | |
| | | | | Minimum timeout or timeout |
| | | | | range are specified by the VNF |
| | | | | Provider (e.g. defined in the |
| | | | | VNFD or communicated by |
| | | | | other means). |
| | | | | |
| | | | | Not relevant in case of forceful |
| | | | | termination. |

+===============+============+=============+=============+=============================================+
| type | M | 1 | Enum | Defines the type of the scale operation |
| | | | | requested (scale out, scale in). The set of |
| | | | | types actually supported depends on the |
| | | | | capabilities of the VNF being managed, as |
| | | | | declared in the VNFD. See note 1. |
+---------------+------------+-------------+-------------+---------------------------------------------+
| aspectId | M | 1 | Identifier | Identifies the aspect of the VNF that is |
| | | | | requested to be scaled, as declared in the |
+---------------+------------+-------------+-------------+---------------------------------------------+
| numberOfSteps | M | 1 | Integer | Number of scaling steps to be executed as |
| | | | | part of this ScaleVnf operation. It shall |
| | | | | be a positive number. |
| | | | | Defaults to 1. |
| | | | | The VNF Provider defines in the VNFD |
| | | | | whether or not a particular VNF supports |
| | | | | performing more than one step at a time. |
| | | | | Such a property in the VNFD applies for all |
+--------------------+------------+-------------+-------------+----------------------------------------+

+---------------+------------+-------------+-------------+---------------------------------------------+
| NOTE 1: ETSI GS NFV-IFA 010 [2] specifies that the lifecycle management operations that expand |
| or contract a VNF instance include scale in, scale out, scale up and scale down. Vertical |
| scaling (scale up, scale down) is not supported in the present document. |
| SCALE_IN designates scaling in. |
| SCALE_OUT 1 designates scaling out. |
| NOTE 2: A scaling step is the smallest unit by which a VNF can be scaled w.r.t a particular scaling |
| aspect. |
