Abstract
This paper presents a comprehensive framework for AI-driven digital twin networks (DTN) that create real-time virtual replicas of physical 6G networks. Our DTN framework uses graph neural networks to model network behavior and reinforcement learning to optimize network configurations in the digital twin before deploying changes to the physical network. Results show that DTN-guided optimization reduces service degradation incidents by 65% and speeds up new service deployment by 4x.
AI Summary
