scale_free

Scale-free infrastructure generator.

This module provides a Barabasi-Albert style topology generator for infrastructure graphs dominated by a small number of highly connected hubs. New nodes attach preferentially to already well-connected nodes, creating a network with a few backbone-like hubs and many low-degree peripheral nodes.

This is useful for infrastructures where QoS depends on hub capacity and resilience: most flows traverse a limited set of critical nodes, so the topology is well suited to studying congestion, bottlenecks, and the impact of hub failures on latency and bandwidth.
