VNF Instantiation

Pre-requisites

• The VNF is part of a Service Model (see: Service Design)

  Note

  In ONAP SDC tool, VNF is named “VF”

Possible methods with ONAP to instantiate a VNF

• With A La Carte method, the user needs to build and send a VNF instantiation request.

  Note 1: prior to be able to send a request to instantiate a VNF, the user needs to instantiate a Service Object and then will need to refer to that Service instance in the VNF instantiate request.

  Note 2: after having instantiated the VNF object, the user needs to instantiate a VF-module object, refering to the previously instantiated VNF object.

  Note 3: the request to instantiate the VF-module object will, at last, send a request to the selected Cloud Platform (Openstack, Azure, K8S…).

• With Macro method, the user do not need to send any VNF instantiation request. VNF instantiation is being automatically performed by ONAP when sending the request to instantiate the Service (see: Instantiate Service).

Possible Tools to perform VNF Instantiation

the user needs such a tool only if using the “A La Carte” method.

• via ONAP VID Graphical User Interface tool

• via any tool able to perform REST API requests (for example : Robot Framework, Postman, Curl…) connected to ONAP SO legacy API.

With “A La Carte” method

• using ONAP VID Portal
• using ONAP SO REST API

With “Macro” method

VNF and VF-Module instantiation are performed automatically when performing Service Instantiation.
