Dataset information                                                           
A sequence of snapshots of the Gnutella peer-to-peer file sharing network from
August 2002. There are total of 9 snapshots of Gnutella network collected in  
August 2002. Nodes represent hosts in the Gnutella network topology and edges 
represent connections between the Gnutella hosts.
