2. R-vCPE/E-vCPE/SD-WAN harmonization discussion
a) Use case goals and their representations of the ONAP functionalities
Enterprise vCPE (Functional Platform Requirements)
SD-WAN
b) Business drivers and application scenarios of the use cases
Enterprise vCPE (Site to Site/Internet/DC)
c) Common features and reusable components between these use cases
Residential vCPE & Enterprise vCPE
Enterprise vCPE & SD-WAN
d) Harmonization Proposals and next stages plan

3. Use Case goals & Representation of the ONAP functionalities
Enterprise vCPE aims to provide the Enterprise2DC efficiently and safely.
Enterprise users receive cloud service based on the operator’s BSS Portal and ONAP.
ONAP is used to instantiate and operate the required vCPE in the access network as a cloud service.
ONAP can also fulfill traffic scheduling in WAN network through the PCE module.
Note: The Enterprise-vCPE use case provide two aspects including the overlay and underlay methods. Also it represents the inclusivity and scalability requirements of ONAP. Our technical proposal can also be applied partly or completely to other Network Providers, so the Branch Offices can establish connections over Internet based on various Network Providers.

6. Business drivers and application scenarios of the use case
Enterprise customers would benefit from cloud services and automation either on-premises or in the cloud depending on their branch configurations. This will free the enterprise users from the installation, local configuration and administration of LAN/NAT/WAN/VPN networking.
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.
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.

7. Business drivers and application scenarios of the use case
Application scenarios of our use cases
The Enterprise vCPE use case supports expanded application scenarios including site to site/DC/Internet which represents the Inclusivity and scalability of the technical proposal for ONAP. The expanded application scenarios show as below:
