2. Standard Adaptation Layer
Controller Scope
SDN-C (and possibly 3rd party controller) will be used for transport configuration – Front Haul, Mid Haul, Back Haul, etc.
App-C (now Generic VNF Controller) is responsible for various network application configuration (PNF / VNF) – DUs, CUs, Disaggregated core, etc.
Also, use multi-cloud layer to configure overlay & underlay networks within a DC
