Summary

Recommendation ITU-T Y.3091 specifies the capability levels and evaluation methods of the digital twin network (DTN) system to help the telecommunication industry reach a consensus on indicating DTN's capability levels, as well as DTN's technical maturity levels. Digital twin network is a virtual representation of the physical network. It is useful for analysing, diagnosing, simulating, and controlling the physical network, and can help the physical network achieve intelligent decision-making and predictive maintenance.
