This section describes Business Drivers needs, Scenarios.
.
Executive Summary - Plug and Play provides a means for a service provider to work with their vendors to have their PNFs be "discovered" by their ONAP deployment through a PNF registration message.
Business Impact - For service providers to discover and deploy a network, Physical Network Functions (PNF) are needed to be deployed and discovered by their network. This serves as a foundation to create a wireless, optical, or wire-line network efficiently. The ability to deploy, discover, manage and incorporate PNFs efficiently is vital to business operations. Without Plug and Play, a service provider and their operator technicians would need to manually create the PNFs into their network which entails a high OPEX and would be very time-consuming and prone to error. For example, Wireless Service Providers will need to roll out tens of thousands of base stations across a nation/world, and the possible and potential business cost savings and expenditures related to rolling out, deploying, and incorporating PNFs to be recognized into a service provider's network encounters vast economies of scale which make Plug and play a vital business imperative.
Business Markets - Plug and Play is applicable to multiple domains, and different kinds of PNFs and applies to any service providers networks.
Funding/Financial Impacts - Without Plug and Play, a service provider and their technicians would need to manually create and deploy PNFs into their network which entails a high OPEX particularly in a 5G RAN wireless network, where it is expected that there will be approximately 10-fold the number of base stations compared to 4G LTE.

STAGES OF PLUG AND PLAY
PNF Plug and Play is used to register a PNF when it comes on-line. This use case is intended to be applicable to a variety of PNFs such as routers and 5G base stations. The steps and descriptions have been drafted to be as general as possible and to be applicable to a relatively wide variety of PNFs. However, the use case was originally developed with consideration for 5G PNF Distributed Units (DU).
