| 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, Slice Profiles), as well as slice termination recommendations (NSI, NSSI). Feature enhancements in Slice selection features. |

| Interface Name | Purpose Reason For Use | API Spec (Swagger) |
|---|---|---|
| CPS-1 | For fetching RAN configuration related info (starting with coverageArea → TA List mapping in H-release) There will be a generic CPS plugin, which could be used as a data source for optimization, since CPS will be persisting the config info of the xNFs in the network, which might be useful for the optimization | https://github.com/onap/cps/blob/master/cps-rest/docs/api/swagger/openapi.yml |
| 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 | https://github.com/onap-oof-pci-poc/sdnc/blob/master/ConfigDB/swagger-json/swagger.json |
| AAIE-1 | OOF interfaces with AAI to retrieve the inventory | OOF consumes a wide variety of inventories from AAI. It can be found under the API section of AAI https://docs.onap.org/projects/onap-aai-aai-common/en/latest/platform/offeredapis.html |
| MCE-5 | OOF queries Multicloud for real-time available capacity information | https://docs.onap.org/projects/onap-multicloud-framework/en/latest/MultiCloud-APIv0-Specification.html |
| MUSICI-1 | OOF interfaces with MUSIC to persist service state. | |
| SDCE-1 | OOF interfaces with SDC to retrieve slice template information | https://docs.onap.org/projects/onap-sdc/en/latest/offeredapis.html |
| DESE-1 | OOF interfaces with DES to retrieve the PM/KPI data of the cells for ML-based decision making. | DES Swagger reference |
| CONSULE-1 | OOF interfaces with consul for configuration management | https://www.consul.io/api-docs/kv |

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:
- Change Management Scheduling optimizer
- 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
- 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 SDNC model)
- Slice/Subnet Profile and Slice/Subnet Instance models, from AAI
6. System Deployment Architecture
...
- Updates to E2E Network Slicing (refer OOFE-6, CPS-1)
- Configuration management using consul kv (CONSULE-1)
- Integrate Generic Optimization Engine into OOF Helm charts (refer OOFE-5)
- Docker image optimizations
