The coexistence of two concepts whose names and meanings are so close
will end in more confusion. In fact, while your definition of NDT is
quite clear, your definition of DTN is not.

The virtual-real mapping you mention is a process required to build and
maintain a NDT. It must not be separated. Let's say that the goal, NDT,
is maintained by process "NDT construction" and this process is part of
what is called DTN. This is confusing.
