...

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 SDC SDNC model)
• Slice/Subnet Profile and Slice/Subnet Instance models, from AAI

7. New Capabilities in this Release

• Component Upgrades to new Policy Lifecycle API
• Support for E2E Network SlicingUpdates to E2E Network Slicing
• Support for inter-domain route optimization
• Support to perform CRUD operations on certain optimization models during runtime.
