netgraph-dsl

What problem does it solve?

NetGraph DSL provides a concise YAML-based language to model, simulate, and analyze complex network topologies, traffic demands, failures, and analysis workflows, enabling repeatable experiments and reproducible results.

Core Features & Use Cases

• YAML-based definitions for nodes, links, demands, failures, risk groups, blueprints, and workflows.
• Flexible selection and expansion patterns (regex path matching, capture groups, variable expansion, and multiple demand modes) to model realistic network scenarios.
• Reusable templates via blueprints and risk-group generation to scale configurations and experiment with different topologies.

Quick Start

Create a minimal NetGraph YAML with two connected nodes (A and B) and a single link to validate the basic topology.
