Using the 8 LFN project, an end user (e.g., a carrier) can realize the above as follows:
Phase 0 - Building the network infrastructure and preparing the network functions
Following the CNTT Reference model, the operator decides which CNTT Reference Architecture may best suit its needs. This is followed by picking a set of infrastructure components that fits a CNTT Reference Implementation of choice. The infrastructure is built using the deployment tolls and CI/CD provided by OPNFV. Next, the infrastructure is certified using the CNTT RC and OPNFV CVC.

Finally, closed loop operations may be further enriched by combining LFN Real Time Analytics capabilities of by SNAS.io (we need a SNAS expert!)and the synergies offered by ONAP and PNDA.io (Donald HunterI am sure we can add A LOT more). Information about changes in the network topology gathered by SNAS can be used to trigger ONAP policies that will spawn more instances of packet routing network functions. The data analytics capabilities of PNDA may be used to trigger ONAP policies based on data streams produced by all layers of the infrastructure as well as the network functions. ONAP may respond to an infrastructure issue detected by PNDA by migrating VNFs from an affected location to one that is healthy and has the available resources.
