OOFE-5OOF Model AdministratorThis 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

Network Slicing

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

6. System Deployment Architecture

...

7. New Capabilities in this Release

  • AAF based authentication and removal of AAF-SMS dependency
  • Enhance NSI/NSSI selection to select NSI/NSSIs based on the current occupancy levels of the network
  • Integrate Generic Optimization Engine into OOF Helm charts (refer OOFE-5)OOF SABRES POC
