I have been asked to review this document on behalf of the OPS Directorate.  This document is an informational description of applicability of ACTN to network slicing.  I found the document very informative and clear on both the ACTN and network slicing fronts.  Admittedly, there are a lot of moving parts in TEAS that are referenced by this document, and I'm sure many operational items when it comes to implementations (the excellent examples in this document highlight these complexities).

In terms of this document, I have one question.  When I look at how the other work with augment the service-level YANG modules and specifically figure 6, why aren't the network models (e.g., L2NM and L3NM) referenced?  I'd think they might be more useful in figure 6 than a direct approach to the physical device interface.
