Interfaces
- 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
- Consolidated Solution 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)
Demand Examples:
{"URLLC":[{"inventory_provider":"aai","inventory_type":"nsi","unique":"true", "filtering_attributes":{"service-role":"nsi","service-function":"shared","model-invariant-id":"21d57d4b-52ad-4d3c-a798-248b5bb9124a","model-version-id":"bfba363e-e39c-4bd9-a9d5-1371c28f4d22"}}, {"inventory_provider":"generator","inventory_type":"slice_profiles","unique":"true", "passthrough_attributes": {"creation_cost": 1.0},"filtering_attributes":{}}]}
Note: Creation cost will come from policy
{
"core": {"latency": {"min": 5, "max": 20, "steps": 1}, "reliability": {"values": [99.9, 99.999]}},
"ran": {"latency": {"min": 10, "max": 20, "steps": 1}, "reliability": {"values": [99.9, 99.9]}},
"transport": {"latency": {"min": 7, "max": 20, "steps": 1}, "reliability": {"values": [99.9, 99.99]}}
}
