Artifact for ATC 2026 Paper "Astragalus: Automatic Configuration Repair for Production Networks"

Synthetic dataset and evaluation data of the paper "Astragalus: Automatic Configuration Repair for Production Networks" (ATC 2026). The repository contains everything needed to rebuild, inspect and re-analyze the synthetic part of the paper's evaluation: Base networks: fat-tree data center networks of 5 sizes (k = 4, 6, 8, 10, 12; 20 to 180 switches), with Cisco-style BGP configurations and a per-prefix forwarding-graph specification. Fault instances: 6,250 misconfigured networks, covering the 15 misconfiguration types of the paper and two kinds of incidents (path change and reachability). Results: the output of one Astragalus repair run per fault instance. Scripts to generate networks and faults, write the fault instances as configuration directories (also in a Batfish-compatible form), and compute the paper's statistics.
