Over the lifetime of the project, we realized the vision of moving from network verification to synthesis, delivering methods and systems that generate and validate network configurations with strong guarantees on correctness, robustness, and performance. Concretely, we developed: (i) synthesis techniques for safe network-wide configuration updates (SIGCOMM) and for correctness-preserving BGP reconfiguration under transient dynamics (SIGCOMM); (ii) methodologies to increase trust in the verification toolchain by systematically uncovering modeling errors (NSDI); (iii) foundational results clarifying what makes network-wide configuration synthesis hard or tractable (ICNP); (iv) techniques to detect and explain transient forwarding anomalies and to predict convergence-time violations (CoNEXT); and (v) the first practical verification of worst-case link-load properties (NSDI). These works were complemented by further works on scalable exploration, causality analysis, and probabilistic reasoning (ICNP), as well as on generating representative traffic for evaluation (HotNets).
Dissemination and exploitation were achieved through 11 peer-reviewed publications and presentations in top-tier venues in computer networks and systems (including SIGCOMM, NSDI, CoNEXT, and ICNP), and through practical artefacts and prototypes (all released in open-source), enabling reproduction and providing a basis for technology transfer. The results also led to interactions with stakeholders (including network operators) and contributed to the training and graduation of multiple PhD students, with several works receiving major recognition and awards.
