NetGraph

NetGraph is a scenario-based network modeling and analysis framework written in Python. It allows you to design, simulate, and evaluate complex network topologies - ranging from small test cases to massive Data Center fabrics and WAN networks.

You can load an entire scenario from a single YAML file (including topology, failure policies, traffic demands, multi-step workflows) and run it in just a few lines of Python. The results can then be explored, visualized, and refined — making NetGraph well-suited for iterative network design, traffic engineering experiments, and what-if scenario analysis in large-scale topologies.
