NSSI Selection

Sequence diagram

Interfaces

1. NSI selection Request
   1. Input: Slice profile
   2. NSST details
2. Fetch Optimization policies
   1. Demand policy for NSSI
   2. Constraint policies for Selection
   3. Optimization policies for NSSI selection.
3. NSSI selection request - HAS
   1. Demand: NSSI
   2. Constraint: Threshold policy, New policy(for CoverageArea )??
   3. Optimization: Maximize/minimize the service profile parameters
4. Fetch NSSI for AAI
   1. Input: NSST info
   2. Output: List of NSSIs as candidates
5. Run Optimization
6. Consolidated Solution based on the policy
   1. Solution List. Solution object can have NSSI

Note:

For the non-shared scenario, No solution will be returned.
