2. API definitions
OOF provides the following interfaces:
| Interface Name | Interface Definition | Interface Capabilities | API Spec (Swagger) |
|---|---|---|---|
| OOFE-1 |
| It enables placement based on a wide variety of policy constraints including capacity, location, platform capabilities, and other service specific constraints. | https://docs.onap.org/projects/onap-optf-osdf/en/latest/sections/offeredapis.html |
| OOFE-2 | PCI/ANR Optimization | Enables PCI/ANR optimization API for SON. | https://docs.onap.org/projects/onap-optf-osdf/en/latest/sections/offeredapis.html |
| 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. | https://docs.onap.org/projects/onap-optf-cmso/en/latest/sections/offeredapis.html |
| OOFE-4 | Route Optimization | Provides an interface for Router Optimization and inter-domain route optimization. | https://docs.onap.org/projects/onap-optf-osdf/en/latest/sections/offeredapis.html |
| 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 (NST, NSI, NSSI), as well as slice termination recommendations (NSI, NSSI). | https://docs.onap.org/projects/onap-optf-osdf/en/latest/sections/offeredapis.html |

| Interface Name | Purpose Reason For Use | API Spec (Swagger) |
|---|---|---|
| SDNCE-1 | For PCI/ANR optimization, OOF Retrieves the Cellsite inventory details from the configdb API, which is hosted as part of the SDNC/R component | |
| AAIE-1 | OOF interfaces with AAI to retrieve the inventory | |
| MCE-5 | OOF queries Multicloud for real-time available capacity information | |
| MUSICI-1 | OOF interfaces with MUSIC to persist service state. | |
| SDCE-1 | OOF interfaces with SDC to retrieve slice template information | |
| DESE-1 | OOF interfaces with DES to retrieve the PM/KPI data of the cells for ML-based decision making. |
