OOF Guilin (R7) Architecture Review

OOF Guilin (R7) 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 Guilin

The key functional enhancements planned for Guilin are as follows:  

  • Enhancements for E2E Network Slicing use case

  • Support for MDONS use case

  • Support for ML based SON optimization 

  • CCVPN route optimization for Transport Slicing
