  1. NSI selection Request
    1. Input: Service profile
    2. NST details
    3. NSST details with subnet capabilities
    4. reuse: true/false
  2. Fetch Optimization policies
    1. Demand policy for NSI and Slice profiles
    2. Constraint policies for Selection
    3. Optimization policies for NSI selection and slice profile generation.
  3. NSI selection request - HAS
    1. Demand: NSI
    2. Constraint: Threshold policy, New policy(for CoverageArea )??
    3. Optimization: Maximize/minimize the service profile parameters
  4. Fetch NSI for AAI
    1. Input: NST info
    2. Output: List of NSIs as candidates
  5. Run Optimization
  6. NSI Solution
    1. Selected NSI candidate
  7. Slice profile generation request - HAS
    1. Demands: Slice profiles
    2.  Constraints: Threshold constraint, CrossDemandAggregation constraint
    3. Optimization:  Maximize/minimize the service profile parameters
  8. Generate slice profiles as candidates and select a suitable set of slice profiles
  9. Slice profile Solution
  10. Consolidated Solution based on the policy

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)
