Features
ONAP ‘Kohn’ focusses on:
Further O-RAN integration with A1 and O1 policy control for SON use cases
improved flows for Cloud-Native Network Functions (CNF) orchestration and upgrade
Intent-driven Closed-loop Autonomous Networks with the CCVPN use case
Robust KPI computation for use in Intent Based E2E Network Slicing
Improved configuration query and change notifications in the Configuration Persistency Service (CPS)
Improved slice analysis in the Control loop automation
Continued modernization of the Policy framework including Service Mesh integration and native Kafka messaging
Security enhancements that include removal of known vulnerabilities and adoption of key software supply chain artifacts
Functional Requirements
Richer set of Cloud Native Functionality
CDS support for Application Service Descriptor
Onboarding ASD CSARs
Transformation to ONAP SDC CSAR
Model updates to support ASD TOSCA types
Support in SDC TOSCA parser
SO improved flows around the CNF orchestration, CNF Upgrade, and minor bug fixes around the slicing use case.
Create multiple PNF instances in the same request
Support for long-running CDS process
Recursive orchestration Support
CNF Upgrade Workflow with Da-2 supported
E2E Network Slicing
Slice Analysis MS enhancement to support real-time intent listening using DCAE SDK dmaap-client lib
KPI Computation MS enhancement to support new KPI reporting to UUI, KPIs spanning multiple resources and error handling for missing counter
Enhancements for Intent-based Cloud Leased Line and Transport Slicing with DCAE SDK alignment for SliceAnalysis MS & enhancing AAI interface for supporting IBN CL
Control Loop evolutions
5G SON use case enhancements including Control Loop message for ANR modified to align with A1-based flow/support
CCVPN enhancements for Intent-based Cloud Leased Line and Transport Slicing
Extended O-RAN Integration
Continued maturing A1-Policy controller functions:
Support updated RESTCONF spec (RFC 8040) between A1 PMS & A1 Adapter
Numerous 3PP dependency updates
Support custom south-bound adapters for custom A1-AP protocol versions
Deprecate DMaaP NBI
Improved logging / Tracing / Metrics
Improved logging/debug-ability in CSIT tests
Support JWT access tokens - for use in service mesh environments.
Additional SONAR reporting for A1-PMS service
Better alignment with O-RAN in the 5G SON use case with use of O1 and A1 interfaces.
Introduction of specific control loop flows for O1-based and A1-based RAN actions. This includes changes in Policy, SDN-R, SON-Handler MS, and RAN-Sim.
Enhancement of RAN-Sim to support A1-based actions
Modification of Control Loop message formats and policies to direct O1 and A1 flows appropriately
Controllers
Resource Resolution Enhancements
Enabled deleting resources by lastN occurrences
Template headers, path, and outputs mapping in the rest processor
The empty Output mapping means for JSON/MAP all keys and for other types extracting of primitive
The empty response is mapped to the value is output mapping is empty (but not null)
Open resolution processors for in-CBA customization
Improve resolution tests verification
Use RestProcessor for testing RestProcessor
Added component for deleting resources and templates
Fixed enrichment for multiple assignments
Fixed the transform-templating for referenced complex types
Creation of dynamic data-type using all workflow steps
CDS now has an endpoint for template deletion
Service Design
Application Service Descriptor support with:
Onboarding ASD CSARs
Transformation to ONAP SDC CSAR
Model updates to support ASD TOSCA types
Support in SDC TOSCA parser
Deletion of archived assets
Improved support for TOSCA constructs
Support for TOSCA value expressions using TOSCA functions
Improved support for import of services
Application metrics
Inventory
Updates to schema and edge rules
Model updates for User Network Interfaces (uni), Route target, Network Route, BGP neighbor, VPN binding, Lag interface, Physical interface and Logical interface
Edge rule changes
ONAP Operations Manager
Update of Infrastructure and tools versions to improve build and deployment time, as well as fixing vulnerabilities
Initial Setup for “ONAP on ServiceMesh” deployment as basis for the London release - using Istio 1.14.1 as SM platform - including Istio Ingress Gateway for external access - modify 90% of ONAP component charts to support Sevice Mesh - Established daily deployment pipelines to test the SM setup
Non-Functional Requirements
The following ‘non-functional’ requirements are followed in the Kohn Release:
Best Practice
Standardized log fields
Support dual stack IPv4/Ipv6 across all ONAP modules
GUI test suites for all UI exposing modules
Security
Adoption of software bill of materials (SBOMs)
Usage of basic images that provide the most updated and secure Java and Python versions
Improve OpenSSF (formerly CII badging)
Documentation
Development guide updated
Structural changes in ‘Guide’ section
Tests & Integration
deployment/noheat refactorization, fixes and updates:
Updated Ansible, Galaxy collections and Python libs to latest versions
Better Galaxy collections and Python libraries versions management
Added playbook to deploy Devstack
Added option to deploy Istio
Ability to set arbitrary overrides file
Added one playbook to deploy whole infrastructure (i.e. create OpenStack VMs in which Devstack, k8s and ONAP gets deployed)
Documentation updates
Important
Some non-functional requirements are not fully finalized. Please, check details on the Integration
Documentation Sources
The formal ONAP ‘Kohn’ Release Documentation is available in ReadTheDocs.
