Hi,

Thanks for the observation and the recommendations.

As one of the coauthors, let me say we already went through this discussion some time ago, and my reckoning is that the use of the term DTN, initially employed, was caused by some language misunderstanding, and that we all agreed on moving towards the more adequate NDT. If there are still remnants of the old naming in the document, this is something that obviously needs to be solved.

Be goode,

Good observation Juergen. I'll let the authors of [1] speak with respect to their document, but looking elsewhere (e.g., ETSI ZSM, papers, etc.) as well as at normal English language usage:

- the digital twin of a network is properly a 'network digital twin' - this is the clear native interpretation of the term as well as the broadly used sense.
- 'digital twin network' does not broadly have the connotation you suggest (a network operated by a digital twin), nor does the term intrinsically suggest such a meaning. If anything, the term suggests a network used in the implementation of a digital twin. I'd thus suggest the term is not a very useful one.

Best

Chris

Subject: [nmrg] network digital twin vs. digital twin network

Hi,

I see both terms being used in [1] but only one of them is defined and I am a bit confused about what the exect difference is between these two terms. Perhaps both should have a clear and explicit definition?

Naively, I assumed that the digitial twin of a network would be called a 'network digital twin' and that a network that is operated by using digital twins as a 'digital twin network' but that does not seem to align with what [1] says.
