Use Case Name

xNF License Management

Business Driver

This section describes Business Drivers needs.

Executive Summary - Continue use case analysis for xNF License Management and derive any requirements to ONAP. The aim is for ONAP to support various types (simple, complex, vendor specific) commercial licensing models and use cases. These will be reflected as multiple, optional solutions for ONAP. The use cases we started with include xNF onboarding, PNF introduction/ONAP PnP, VNF instantiation. Further use cases to be analyzed, eg. usage monitoring for the purpose of invoicing. Based on agreed use cases review relevant ONAP xNF requirements. Possible SW contributions, eg. in SDC, as well as enhancement of ONAP architecture sequence diagrams.

Business Impact - xNF License Management is a critical business function. Agreed use cases should allow ONAP to flexibly support commercial licensing models.

Business Markets - The requirement applies to any domain (wireless, transport, optical, wireline) that ONAP will manage. It is not a market specific function.

Funding/Financial Impacts - The use case is fundamental for supporting efficiently business agreements between the operator and the vendor.

Organization Mgmt, Sales Strategies -There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.
