摘要：This paper discusses problems on scale-free network traffic, with the bandwidth considered as the delivering ability of links. Moreover, the traffic model of scale-free network is established, with the fixed bandwidth, which means the delivering ability of each link as a constant in the network. For better understanding traffic dynamic in real systems, the effects of bandwidth on the packet delivering of the traffic systems have been focus on. Meanwhile, some phenomena are found from the simulations, and the change of network load with different bandwidths is researched qualitatively in a 'tunable clustering coefficient' BA scale-free network and on the background of information traffic. The capacity of network load is higher in the network with the plenteous bandwidth, on the contrary, the capacity of network load degreases substantially induced by the bandwidth declining. In the light of the theory of complex network topology and traffic, the analytical explanations are provided on the change of the capacity of network load with the restriction of bandwidth.
