Usecase 1 – Upgrade Image Vendor has a new Image for the VNF requiring Image upgrade for all the existing VNF Instances Vendor works with the VNF Owner to define the workflow for upgrading the VNF Image New VNF version includes the updated image and the workflow to upgrade the image from the previous VNF version to the current VNF version Service is updated with the new VNF version and distributed MSO deploys the workflow On MSO receiving the VNF Upgrade request from VID/CCD/OMX. MSO executes the workflow previously deployed to Upgrade VNF

Usecase 1 – Upgrade Image contn.. Stop traffic is a API call to controller so controller can actually take the necessary steps to stop traffic Drain traffic is an API call to controller to allow for controller to confirm completion of all the in- progress activity in the VNF Create VNF is an API call to Openstack to instantiate the VNF All the steps are API calls from MSO to various systems with inter-dependencies

Who? - Users Tooling is for the Designer(Workflow Designer)

High Level Solution Activity Definition/Specification abstracts implementation details of the Activity from the Designer Note: Activity is an extension or capability of SO, for example SO’s ability to invoke a Component API (Controller, A&AI, etc..). New Activities are developed as part of a specific ONAP release. Activities are normally automated and in some cases manual Activity Implementation can be based on BPMN, Java or any other scripting API calls to other ECOMP components like controllers, SNIRO, Micro-Services, etc. Re-usable building blocks/BPMN processes in MSO Manual Task Workflows shall be made of Activities with inter-dependencies between them Enhance VNF and/or Service Model to include Operations and optionally Workflows implementing the Operations Instantiation Workflow – Instantiate a VNF, which includes assignments, creation and configuration. i.e., what ever is required to for VNF to be deployed and serve/provide it’s functionality Disconnect Workflows Upgrade Workflow – Upgrade VNF from a particular version to later version of the Service or VNF Model More..
