2. API definitions
OOF provides the following interfaces:
| Interface Name | Interface Definition | Interface Capabilities |
|---|---|---|
| OOFE-1 |
| It enables placement based on a wide variety of policy constraints including capacity, location, platform capabilities, and other service specific constraints. |
| OOFE-2 | PCI/ANR Optimization | Enables PCI/ANR optimization API for SON. |
| OOFE-3 | Schedule Optimization | a policy driven workflow schedule optimizer for change management planning. This interface schedule workflows in time to maximize parallel change management activities, while respecting dependency between the workflows. |
| OOFE-4 | Route Optimization | Provides an interface for Router Optimization. |
| OOFE-5 | OOF Model Administrator | This is for the OOF Model Administrator API. This API is a way to dynamically change the optimization models that will be used to find solutions for various optimization problems. This API will be used to Create, Update or Delete Models. |
| OOFE-6 | This interface enables slice selection recommendations. |
Note: xxxI interface is a Component internal interface. xxxxE interface is a component external interface

5. Used Models
OOF doesn't directly create models, but indirectly consumes them via AAI, Policy and Multi Cloud.
- Service and Resource Info, from: AAI
- Network Topology for CM: AAI
- HPA Flavors/Capabilities/CapacityInfo, from : AAI
- Policy Models (homing, PCI) from: Policy
- Infrastructure Metrics Info (capacity), from: MultiCloud
- Cloud agnostic Intent Info, from: MultiCloud
- AZ level capacity Info, from: MultiCloud (for F-GPS)
- PCI configuration data(not yet a part of SDC model)
- Slice/Subnet Profile and Slice/Subnet Instance models, from AAI
