Overview

Scope

What is this release trying to address?

Committed: 

Functional Requirements

• F-GPS - Main purpose of F-GPS (a.k.a. ONAP-Valet) is, with considering new placement policies,  to precisely check capacity & capability of target Cloud Region and then, to determine VNF placements (i.e., target zone for each workload (VDU) of VNF). Resources from IBM
  Goals
  • Capacity & Capability checking for an OpenStack cloud: 
  • Checking the number of zones of the target Cloud Region to solve the Anti-affinity rules.
    • Checking available capacity of each zone to solve Affinity rule.
    • Checking available host profiles of each zone to solve flavor matching (i.e., Host-Aggregates) (Stretch Goal).
  • Placement decisions for Affinity and Anti-Affinity among zones of target Cloud Region. Optionally, decisions go into compute hosts (for private cloud case).
  Stretch Goals
  • Defining Affinity and Anti-affinity rules in Policy. Until this is ready, evaluate with a manual/hard-coded policy.
  • Specifying Affinity and Anti-affinity rules in homing/placement request. Until this is ready, evaluate with a manual/hard-coded specification.
  • Distributed cloud modelling immediately relevant to F-GPS - a single cloud control plane (Cloud Region) to be able manage several distributed DC locations/zones. 

  • Leverage capacity alerts (significant change in capacity) from Model-driven Distributed Analytics work.

• Policy Tosca model API and ONAP CLI integration Resources from Intel
  Goal 
  
  • Develop APIs in Policy for uploading policy tosca models for OOF.
  • Develop CLI for creating the policies including templates using ONAP CLI project. This will be extremely valuable in automating policy creation, one of the major pain points in Casablanca integration tests.
• CMSO 
  
  • Traffic Migration Workflow Resources from Orange
  • Schedule Optimization with Automated Conflict Avoidance (Stretch goal based one resource availability)
    
• OOF PCI Optimization Resources from WIPRO, AT&T
  • OOF PCI Solver and interface shall support at least two optimization objectives (e.g. minimize changes, minimize PCI confusion)
  • OOF PCI Solver policy shall use a PCI range specified in the configuration policy
  • OOF shall provide a joint PCI/ANR solver which will optimize PCI and also recommend a removal of a neighbor relation if there PCI allocation is difficult for a cell which also has a neighbor link for which the successful_handover KPI is below a pre-specified threshold

  • CI/CD enhancement - Continuous Deployment (Comply with the requirements from Task force). Enhance existing CI jobs for Dublin.
  • Unit test coverage to 60% or 70%?
  • Improve OOM deployment time for OOF helm charts.

Stories

Longer term roadmap

As the ONAP platform matures and new capabilities are introduced over time, the need for platform optimization services will grow along with it. The ONAP Optimization Framework is envisioned to handle this need as effectively as possible, by enabling creation of new optimization services with minimal or little new code development. The goal of OOF is to provide a growing set of core platform optimization services such as VNF placement and resource allocation (OOF-HAS), change management scheduling (OOF-CMSO), etc. 

Vision for OSDF:

OOF-OSDF is envisioned to be a collection of design time optimization libraries along with reusable runtime tools and microservices to facilitate and simplify the creation of new specific runtime optimization functionalities. The goal of OSDF is to avoid siloed optimization tools and associated duplicated efforts and overheads. For instance, the Homing Service, HAS (which was provided in the Beijing release) will not only contribute its reusable components to the framework, but also leverages the framework in its own feature development. Other potential optimization services that can be built using this framework include energy optimization in networks, optimal route selection for various network services, and radio access network (RAN) performance optimization. 

Vision for HAS:

OOF-HAS, or the Homing Service is a distributed resource broker that enables automated policy-driven optimized placement of services on a global heterogeneous platform using ONAP. HAS is architected as an extensible homing service that can accommodate a growing set of homing objectives, policy constraints, data sources and placement algorithms. It is service-agnostic by design and can easily onboard new services with minimal effort. HAS is designed to be used as a building block for both initial deployment, as well as runtime redeployment due to failures or runtime-capacity increase (scale-out). While the initial  deliverable of HAS is to provide optimized homing/placement of services during the service instantiation workflows in ONAP,  HAS naturally extends to a general policy-driven optimizing placement platform for all platform placement functions, including placements of VMs, containers (e.g., for DCAE micro-services), ONAP Control Loops or VNF specific resources. HAS will also eventually allow placements of additional resource types such as licenses, VNF resources, etc.
