  Many concepts in network science are based on idealized network models.
Infrastructure networks, however, are strongly constrained by specific
engineering and economic constraints which do not appear in such models. One
result is that concepts which are assumed to be fundamental by theoriticians
severely underperform in real world situations. This motivated us to test if
the Expected Force (ExF) metric, which was developed in the context of more
theoretical network models, would continue to be predictive of epidemic
outcomes on the highly structured topology of the internet at the autonomous
systems (AS) level router connectivity. Results suggest that the ExF performs
extremely well on these topologies, perhaps reflecting their design constraint
of easing the diffusion of information.
