1. AS Graph Data Sets

For a given date, we collected two AS graph instances. The first AS graph instance contains AS-level connectivities inferred from Oregon route-views. The second instance incorporates not only Oregon route-views, but also Looking glass data and Routing registry data. These were collected once a week, on the same day of the week, for 9 consecutive weeks starting Mar. 2001. Click here to download them.

The contained individual files are peer.oregon.[collection_date] and peer.oregon+.[collection_date]. The former contains pairs of interconnected ASs according to the Oregon route-views of a given collection date. The latter contains AS interconnection info from (1) Oregon route-views, (2) Looking glass, and (3) Routing registry. Each peer file contains a set of lines formatted as "X:Y", which means that AS X and AS Y has direct peering relationship between them. The total number of lines in the file corresponds to the total number of undirected edges in the resulting AS graph. For more information on how we obtained these data sets, please refer to our paper.

More recent AS graph data sets which were collected on May 15,2002 are available here. Please refer to README file in the tarball for more details.

2. The Barabasi-Albert (BA) Model

ba_model.tar contains the collection of scripts and programs that we used to validate the BA model. It also contains relevant datasets that include (1) a set of daily peer files constructed by a fixed set of 14 peers, (2) a set of corresponding daily AS degree info files. Those datasets span from March 2000 to September 2001. Refer to README file in the tarball for more information.
