Hi again Daniele,

You are comparing two things that are not the same.

The Network Slicing NBI is a YANG model for use on the customer service interface. That is, it allows the customer and provider to communicate about the network slice that is to be provided. 

ACTN is an architecture. That is, it describes how the management components may be arranged/structured to deliver function in a network.

 

You can use the Network Slicing NBI at an interface in the ACTN architecture.

It could be used at the CMI (in the same way that the L3SM and L2SM can be): see Section 4.1.

Or it could be used above the CNC: see Section 4.2

 

Best,

Adrian
