This page describes the creation of a network example - or instance model. It should guide the discussion about network creation as composite of cloudified and physical network functions for different technologies (RAN, Transport, Core and Cloud).
Several formats of the same network instance are used to describe the network in an abstract way.
For the description of the network topology - the association between the network functions - the ietf-network-topology model according to https://datatracker.ietf.org/doc/html/rfc8345 is used
Radio Access Network
The Radio Access Network follows the O-RAN Architecture.
5G Core
The most simplistic way is to create only one 5G-Core instance for the network. The description of interfaces between the RAN and the 5G Core, only one UPF and only one AMF will be instantiated and added to the network topology.
