OOF provides the following interfaces:

...

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
