DTN
Digital Twin Network
A high-fidelity real-time virtual replica of the physical 6G network infrastructure used for predictive simulation, zero-risk validation, and proactive optimization.
Technical Explanation
The 6G Digital Twin Network (DTN) mirrors every physical and virtual network element, radio channel state, user mobility trajectory, and compute resource in software. By streaming ultra-fine-grained telemetry from the live network into high-performance physics and AI simulation engines, the DTN models the impact of configuration changes, security patches, radio beamforming alterations, and disaster failure scenarios before applying them to production infrastructure.
Key Functions
- Real-time bidirectional synchronization with physical 6G RAN and Core infrastructure
- Safe sandbox verification for autonomous AI policy models and software updates
- Predictive failure analysis and proactive traffic rerouting before outages manifest
- Simulating complex non-terrestrial satellite constellation handovers and Doppler shifts
- Continuous training ground for multi-agent reinforcement learning (MARL) algorithms
