In recent years, a variety of overlay networks are created over the Internet via virtual links. We investigate the impact of the virtual link configuration on the network capacity with a dual-layer lattice network model, focusing on the critical value of the input rate of user traffics. A mean-field theory suggests that the critical traffic is, approximately, inversely proportional to the average trip of virtual hops on the infrastructure. Simulations verify the analytic result and further show that the behavior of the overlay-physical network interactions is significantly divergent with different link configurations. Therefore, the optimization of virtual links will be conducive to improving the effectiveness of overlays.
