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-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, Slice Profiles), as well as slice termination recommendations (NSI, NSSI). |

ONAP Optimization Framework (OOF) is an Umbrella project, with the primary goal of addressing the optimization needs of ONAP. OOF is a framework that supports creating and running a suite of Optimizing applications including:
- Homing/Placement optimizer
- PCI optimizer
- Route optimizer
- Slice selection
OOF is targeted to be an optimization platform with the following goals:
- Declarative, policy-driven approach to solving optimization problems
- Reusable components: data and policy adapters/libraries, execution environment
- Support General-Purpose as well as Custom optimizers
- Extensible to multiple optimization problems
Internally, OOF has the following components:
...
OOF doesn't directly create models, but indirectly consumes them via AAI, Policy and Multi Cloud.
- Service and Resource Info, from: 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
- PCI configuration data (not yet a part of SDNC model)
- Slice/Subnet Profile and Slice/Subnet Instance models, from AAI
