Key Contacts - @Byung-Woo Jun (Ericsson), ...
Executive Summary - Provide ASD-based CNF orchestration support through SO and its sub-components, CNFM and CNF Adapter
- Support for provisioning ASD-based CNFs using an external K8s Manager
- Support the Helm based orchestration
- leverage and enhance SO Catalog DB handler (ASDC Controller)
Business Impact - Enables operators and service providers to orchestrate ASD-based CNFs services along with the VNFs and PNFs
Business Markets - All operators and service providers that are intended to use the CNFs along with PNFs / VNFs
Funding/Financial Impacts - Reduction in the footprint of the ONAP for CNF support
Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this requirement outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider
