Autonomous systems - Oregon-2

Dataset information

9 Autonomous systems graphs, 1 per week between March 31 2001 and May 26 2001. Graphs represent AS peering information inferred from Oregon route-views, Looking glass data, and Routing registry, all combined.

Dataset statistics are calculated for the graph with the lowest (March 31 2001) and highest (from May 26 2001) number of nodes:
