OOF Frankfurt (R6) Architecture Review

OOF Frankfurt (R6) Architecture Review

1. Project Overview

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

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: 

  • OSDF: Optimization Service Design Framework, which is a collection of APIs and libraries, along with a generic runtime optimizer

    • Status: Part of ONAP since Beijing Release.

  • HAS: Homing and Allocation Service, which provides a policy based constraint driven selection optimizer

    • Status: Part of ONAP since Beijing Release.

  • CMSO: Change Management Schedule Optimizer, providing schedule optimization

    • Status: Seed code up-streamed in R3

  • FGPS: Fine Grained Placement Service

    • Status: Seed code up-streamed, POC in Frankfurt

2. Functional enhancements for Frankfurt

The key functional enhancements planned for Frankfurt are as follows:  

  • Moving to new Policy APIs as a part of Component Upgrades to new Policy Lifecycle API

  • Support for E2E Network Slicing

  • Internal re-architecture to allow streamlined onboarding of new optimization use cases. 

  • CCVPN route optimization
