Demand will be a Network Slice

Interfaces

1. NSI selection Request
   1. Input: Service profile
   2. NST details
   3. NSST details with subnet capabilities
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

Demand

Candidates:

• NSI (AAI Inventory)
• Slice profiles (Generator)

Demand ExampleExamples:

Policy:

ax+by

min → (cost) + 0.1(latency)

...

min→ 0.5 (cost) + 0.5(latency)

max → (cost) 

NSI - Cost (2) - Latency -10 ms

SP - Cost (10) Latency -5 ms

List of Constraints

• Threshold Constraint (Matching NSI)
• Aggregation Constraint (Matching aggregated slice profiles)
