    Gnutella peer-to-peer network, August 24 2002                                 
    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.
