1. ONAP - Workflow Designer

2. Workflows & VNF Operations
Workflow Designer
Problem Statement:
Design in SDC 1
Each workflow requires SO development (sometimes per VNF)
Tech Ops 2
Operations Team have to wait on release cycles for any requested workflow change
Automate
Workflows & VNF Operations
VID, SO
Deploy VNF, Operations & Workflow
Goal:
Tech Ops will be able to use SDC to design workflows for SO – e.g. VNF Image/Software Upgrade, VNF Configuration Upgrade & VNF Scaling
Initiate VNF Operations/ Workflow
Reusable building blocks(Activities)
Execute Workflow

5. Workflow Designer – Generic Workflow
1. Activity is Developed in SO & ActivitySpec is On-boarded to Catalog
2. Workflow Designed in SDC using Workflow Editor and BPMN Artifact is generated

6. Generic Workflow Capabilities
Designer is able to define
Workflow
Inputs and Outputs of Workflow
Manage Activities of Workflow
Establish dependencies between Activities in a Workflow
Map Inputs and Outputs of Workflow/Activity to Inputs and Outputs of an Activity

7. Generic Workflow Capabilities – Generic Activity Implementation
Workflows should not be impacted when Activity Implementation changes
Workflows are defined using Activity Specifications. Activity Specification define interface of Activity Implementation. Any changes to Activity Implementation with-out impacting interface has no change to Activity Specification or workflow
To generate a executable BPMN all Activity Implementations are wrapped in a single Activity Implementation to be used in BPMN

10. Terminology
ActivitySpec – Definition of an Activity that is exposed to the Designer. Includes information like Name, Inputs & Outputs
Workflow – Represents the Business Process executed in SO or any other orchestration (workflow execution) engine
Operation – Operation supported by a Managed Entity like Service, Resource(PNF, VNF, Network) and Resource Components(VNFCs)
