The information was obtained by collected routes of Oregon route-views project, and enriched with a large quantity of links, and obtained using informations from peering relationships of the autonomous systems, is presented in Chen et al. 2002. Colors are assigned according to the coreness: vertices with coreness 1 are violet, and the maximum coreness vertices are red, following the rainbow color scale. The node degree scale is also displayed, showing the maximum degree of the network. Return <-
