Hi Pedro, 

Sorry for the late response. Thanks for your valuable comments. 
We will consider to add some short description to compare architecture of Digital twin network with one or two typical network management architecture in future version of the I-D. 

Thanks and Best Regards,
Cheng Zhou

Dear Cheng,

The overall proposal in this I-D is an enlarged version of a typical
closed-cycle autonomic network management architecture. It has been
enlarged by instantiating a simulator together with the model building
and other elements of the analysis stage and knowledge base. Moreover,
it has increased requirements for input data, so that both models and
simulators have a more realistic view of the network. Because of this I
find the document lacks a mapping of the reference architecture and the
typical network management architecture, both abstract, in terms of, for
instance, MAPE loop, as well as an implementation, as Open Source MANO.
