- NSI selection Request
- Input: Service profile
- NST details
- NSST details with subnet capabilities
- reuse: true/false
- Fetch Optimization policies
- Demand policy for NSI and Slice profiles
- Constraint policies for Selection
- Optimization policies for NSI selection and slice profile generation.
- NSI selection request - HAS
- Demand: NSI
- Constraint: Threshold policy, New policy(for CoverageArea )??
- Optimization: Maximize/minimize the service profile parameters
- Fetch NSI for AAI
- Input: NST info
- Output: List of NSIs as candidates
- Run Optimization
- NSI Consolidated Solution
- Selected NSI candidate
- Slice profile generation request - HAS
- Demands: Slice profiles
- Constraints: Threshold constraint, CrossDemandAggregation constraint
- Optimization: Maximize/minimize the service profile parameters
- Generate slice profiles as candidates and select a suitable set of slice profiles
- Slice profile Solution Consolidated Solution based on the policy
- based on the policy
- Solution List. Solution object can have NSI/Slice profiles
Note:
For the non-shared scenario, Only slice profiles will be generated. HAS need not fetch the existing NSIs.
Demand
Candidates:
- NSI (AAI Inventory)
- Slice profiles (Generator)
