Network infrastructure management faces challenges due to multi-vendor environments, historical configuration debt, and constant operational changes. Traditional manual testing often fails to predict failures in complex systems, leading to outages after minor software updates.
Experts propose a digital twin approach to manage network changes. This framework integrates three distinct tools: physical labs for hardware validation, emulation for testing configurations in virtual environments, and simulation for modeling network-wide states.
Physical labs utilize spare equipment to validate specific devices or firmware under load. Emulation, such as the uInfraTwin solution, creates virtual segments to test scenarios before deployment. Simulation tools like Hadal, Batfish, or IP Fabric model the entire network to track traffic paths and policy drift.
The digital twin lifecycle consists of three stages: network archaeology to map the actual infrastructure, pre-deployment testing of configurations and releases, and ongoing post-deployment monitoring. This process helps identify discrepancies between intended and actual network states.
