Validate Every Build Continuously

Modern switching and routing changes can introduce unexpected behavior long before full-scale deployment, especially when topology updates, protocol interactions, and scale conditions evolve across physical and virtual environments. Validating these changes manually is difficult because regression issues may appear only under repeatable traffic patterns, time-varying load conditions, or specific control-plane and data-plane combinations, making early fault isolation slower and increasing the risk of escaped defects in production networks.

Effective network regression testing requires automated, programmable workflows that can recreate topologies, protocol states, and traffic conditions consistently across development cycles. Engineers need repeatable test execution to verify routing behavior, interoperability, resilience, and system readiness as software, configurations, and infrastructure designs change, allowing teams to catch failures earlier, reduce manual retest effort, and improve confidence in continuous integration and continuous delivery (CI/CD) network validation pipelines.

Automated Network Regression Testing Solution

Testing and automating network regression workflows requires open, programmable traffic generation and protocol emulation that can run consistently across physical and virtual test environments. Keysight Elastic Network Generator supports this approach with a software-defined architecture and Open Traffic Generator (OTG) API control, enabling engineers to automate repeatable switching and routing validation, create scalable time-varying flows, and accelerate CI/CD-based regression testing for interoperability, topology changes, and evolving network behavior.
