## Resource

Episode 70 of Networking Tech with Fexingo explores network digital twins—virtual replicas of production networks used to simulate changes, test configurations, and predict failures before they impact users. Lucas and Luna break down how AT&T and Microsoft are deploying digital twins to reduce planned maintenance windows by 70 percent and prevent capacity-related outages. They walk through a concrete example: simulating a BGP policy change on a core router to see if it would create a routing loop. The hosts explain the key technologies—model-driven telemetry, graph databases, and real-time state synchronization—and why digital twins are becoming essential for any organization running complex, multi-vendor networks. They also discuss the limitations: fidelity gaps where the twin doesn't perfectly mirror the production device, and the compute cost of running high-fidelity simulations at scale. A practical, technical look at a technology that's quietly changing how network engineers plan their work. #NetworkDigitalTwins #AT&T #Microsoft #BGP #ModelDrivenTelemetry #GraphDatabase #NetworkAutomation #NetworkObservability #PredictiveMaintenance #RoutingLoops #MultiVendorNetworks #NetworkSimulation #NetworkEngineering #Technology #FexingoBusiness #BusinessPodcast #InternetInfrastructure #NetworkingTech Keep every episode free: buymeacoffee.com/fexingo
