Overnet traces
To measure availability in P2P systems, we collected data from the Overnet file-sharing network over a period of 7 days in January 2003. There are two parts to the data, the prober data and the crawler data. The prober concentrates on the behaviour of a fixed set of 2400 hosts. The crawler data provide a view of host availability in the whole network. More information can be found in our publication, "Understanding Availabilty", that was presented at IPTPS 2002.
The following tarball contains these data, and a README explaining the nature and format of the data.
