Modularity structure is often found in many different types of complex networks. Especially, this topological property is believed to provide a certain degree of robustness to networks. This belief leads us naturally to investigate the impact of modularity structure on the behavior of networks. In this paper, we carry out two simulation studies to monitor traffic dynamic in modularized and non-modularized scale free networks. In the first simulation, coarse-grained traffic is flooded through

In the second simulation, more fine-grained traffic is used to investigate how a modularity structure impacts on the saturation of networks. This result shows that a strong modularity structure is saturated much faster than non-modularized topology as traffic load increases, and additionally we show how this early saturation in modularized structure can be overcome.
