Overview
ACTN refers to the set of virtual network operations needed to
orchestrate, control and manage large-scale multi-domain TE networks
so as to facilitate network programmability, automation, efficient
resource sharing, and end-to-end virtual service aware connectivity
and network function virtualization services.

Customer Network Controller
A Virtual Network Service is instantiated by the Customer Network
Controller via the CMI (CNC-MDSC Interface). As the Customer Network
Controller directly interfaces the application stratum, it
understands multiple application requirements and their service
needs. It is assumed that the Customer Network Controller and the
MDSC have a common knowledge on the end-point interfaces based on
their business negotiation prior to service instantiation. End-point
interfaces refer to customer-network physical interfaces that
connect customer premise equipment to network provider equipment.
In addition to abstract networks, ACTN allows to provide the CNC
with services. Example of services include connectivity between one
of the customer's end points with a given set of resources in a data
center from the service provider.
...
The PNC, in addition to being in charge of controlling thephysical
network, is able to implement two of the four ACTN main
functionalities: multi domain coordination function and
virtualization/abstraction function
A hierarchy of PNCs can be foreseen for scalability and
administrativechoices.
