Description:
This use case is mainly used for the Enterprise Service Provider (SP) to provide the Enterprise2DC service to the tenants both efficiently and safely by deploying enterprise-based vCPE. Enterprise users could receive high-quality and cheap cloud service based on the operator’s BSS Portal and ONAP. And in here, ONAP is used to instantiate and operate the required vCPE in the access network as a cloud service.

Enterprise vCPE Scenario diagram as shown below:
Users and Benefit:
...
SPs would benefit from a more flexible platform to provide more kinds of virtual services. To implement the configuration remotely will help SPs reduce complexity of the service deployment and cut down the OPEX. Besides, ONAP can manage a large number of business orders from BSS or user self-service systems, which can improve service efficiency. The order management services include three core functions, such as order resolution and calibration, order execution, and order reporting.
The centralized traffic scheduling and optimization of backbone network is the embodiment of SDN concept in backbone network, it will help operators enhance the management ability of operation and maintenance and improve the efficiency of resource utilization.
...
ONAP collect link utilization and the actual traffic flows in real-time. when the flow reach the WAN side, the ONAP will conduct the optimal path calculation through configuring MPLS TE tunnels, so as to realize the function of traffic scheduling.
