 "J" = 0 means no congestion, and "J" = 1 corresponds to maximal congestion.In the limit N → ∞,and the probability with which two arbitrary nodes are connected is constant, for random network, the congestion factor becomes

This result show that random networks are maximally congested in that limit.On the contrary, for scale-free network, J is always a constant for any N. This conclusion means scale-free networks are not prone to maximal jamming.
