On the Scale-Free Structure of Netowork Topology on End-to-End Performance

Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, it has been reported that several existing networks represented by the Internet have a scale free structure. In this paper, through a simple numerical analysis, we investigate what effect the scale free structure of communication networks has on its end-to-end performance. As topologies of a network, a random network and a scale-free network
with the equal number of nodes and the equal number of links are used. We compare end-to-end performance of flows (i.e., throughput) in both random and scale-free networks. Consequently, we show that when the average degree of a network is small (i.e., the number of links is small), a scale-free network shows better end-to-end performance. On the contrary, when the average degree of a network is large (i.e., the number of links is large), we show that a random network shows better end-to-end performance.
