To be precise, the term “virtual DC” would be as defined in RFC 7365 *if* that term were used.  The virtual DC term is not used in this draft and it’s also not used in RFC 7365 outside of its definition in section 1.1.

The terminology is not different, but the virtual DC concept is not needed to describe the NVO3 architecture or the NVO3 framework.

Sure, see section 4.3 of the NVO3 use case draft - vDC could be mentioned as a use case example if a reference to that use case draft is added.

No it wasn’t - neither the “vDC” acronym nor its “virtual DC” expansion appear in the NVO3 architecture draft.

in the section 2 it is clear:
section 2 draft> This document uses the same terminology as

[RFC7365].

IMHO, it means that this draft has same terminology included in the draft as rfc7365 (i.e, virtual DC is defined in RFC7365). It is used in many drafts in IETF that authors don't like to repeat such similar RFC with similar approach (even in scientific articles it is great practice to reference related work).

Thanks for your replies,
