This section aims to present an end-to-end use case where the 8 LFN projects work in harmony to deliver a "service" that includes VNFs, connectivity and analytics-powered assurance as shown in the following picture:
In this example, 2 VNFs (for the sake of simplicity, provided by the same vendor) must be deployed on top of an NFVI (e.g., OpenStack), be interconnected and provided with external connectivity to the Internet. Moreover, the VNFs require network acceleration and the whole service must be assured using Analytics driven closed loop operations.

- OpenDaylight and Tungsten Fabric can be used as3rd party SDN solutionsto provide network connectivity.
- Open Switch (OPX) can be used to configure the physical (underlay) network that connects the physical hosts used to deploy OpenStack The network topology may follow the leaf and spine topology as a physical infrastructure is recommended in the requirements of physical infrastructure of the CNTT Reference Architecture.
- FD.io provides data plane network acceleration through its Vector Packet Processor (VPP).
