Description


Graph of Autonomous Systems (AS). Each AS exchanges traffic flows with some neighbors (peers). We construct a communication network of who-talks-to- whom from the BGP (Border Gateway Protocol) logs.

The data was collected from University of Oregon Route Views Project - Online data and reports. The dataset contains 733 daily instances which span an interval of 785 days from November 8 1997 to January 2 2000. In contrast to citation networks, where nodes and edges only get added (not deleted) over time, the AS dataset also exhibits both the addition and deletion of the nodes and edges over time.

Dataset statistics are calculated for the graph with the highest number of nodes and edges (dataset from January 02 2000):
