Abstract: The study of traffic dynamics on multi-layer network contributes to revealing the traffic law of the actual network and suppressing the occurrence of network congestion. Focusing on actual network traffic characteristics, we construct a three-layer network model which consists of one logical layer and two physical layers. The traffic dynamics of the three-layer network model are carefully compared with different logical layer routing strategies. In addition, three indicators of load average, load standard deviation and load reduction rate are proposed to more intuitively observe the load conditions of physical layer nodes. We also study the impact of the degree distribution of physical layer on traffic capacity of three-layer network. It is found that when the preference of packets selection for small degree nodes is insufficient or excessive, it is not conducive to achieving higher traffic capacity.
