Summary

A new data-driven Network Digital Twin (NDT) framework, extending 6G-TWIN, has been developed to enable trustworthy what-if analysis for 6G cloud-edge infrastructures. This framework addresses fragmented workflows from telemetry to validation by providing a scalable pipeline for telemetry aggregation and semantic alignment into unified data models. Key contributions include scalable cloud-edge telemetry collection, regime-aware feature engineering to capture network scaling behavior, and a validation methodology utilizing Sign Agreement and Directional Sensitivity. Evaluated on a Kubernetes-managed cluster, the framework successfully extrapolates performance to unseen high-load regimes. Both Deep Neural Network (DNN) and XGBoost models achieved high regression accuracy (R2 > 0.99), with XGBoost demonstrating superior directional reliability (Sa > 0.90), positioning the NDT as a reliable tool for proactive resource scaling in out-of-distribution scenarios.

Key takeaway

For Research Scientists developing 6G network management solutions, this NDT framework offers a validated approach to proactive resource scaling. You should consider implementing its scalable telemetry and regime-aware feature engineering, particularly leveraging XGBoost for its superior directional reliability (Sa > 0.90) in out-of-distribution scenarios. This can significantly enhance the trustworthiness of your what-if analyses for cloud-edge infrastructures.
