}
- Input: Service profiler parameters.
- Fetch Optimization policies
- vnfPolicy - it will identify the inventoryProvider and inventoryType - Forms demand policy.
- Attribute policy - for storing the serviceprofileparameters and its value as attribute - value pair- Constraint policy.
- QueryPolicy - Its used to query the serviceprofileparameters from the input so that it can be added as a value to the attribute.
- NST selection request - HAS
- Demand: NST
- Constraint: Attribute policy for matching whether nst templates have these attributes.
- Fetch NST metadata from AAI
- Output: List of all NSTs metadata
- Sample Request:
