| Abstract(in English) | Modeling the Internet is vital for network researches. Recent measurement studies on the Internet topology show that the degree distribution obeys power-law distribution. However, only the degree distribution does not determine the performance of network control methods. As previous studies have shown, one of important factors to characterize the performance of network control methods in the Internet is the topological structure. However, other factors, which are even more important, are link capacities and node processing capacities of the network because these are features particular to communication networks. In this paper, we investigate how to model the link capacity in the router-level topologies. We first reveal that the link capacity distribution of ISP's backbone network in Japan obeys the power-law distribution. We then evaluate the network throughput of power-law distribution of link capacities. Our numerical results show that the network taking power-law capacity distributions can accomodate much more traffic than the network taking exponential or uniform capacity distributions. |
