Validation of the microscopic congestion model with Barabási–Albert (a,b) and Erdos–Rényi (c,d) networks of 1000 nodes and shortest path routing strategy. In the construction procedure of the Barabási–Albert networks each new node is connected to one existing node in the network. The Erdos–Rényi networks have an average degree of 50. In (a,c), accuracy in predicting the order parameter η. In (b,d), correlation between predicted and simulated values of d_i. Vertical solid lines on panels (a,c) show the predicted critical generation rate ρ_c. Vertical dashed lines show the ρ values where d is evaluated on the panels (b,d).
