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.

Physical Network Controller

The PhysicalNetworkController is PhysicalNetworkControlleris the one in charge of configuring
the network elements, monitoring the physical topology of the
networkandpassing it, either raworabstracted, to the MDSC.

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
administrative choicesadministrativechoices.
