Abstract: With the rise of peer-to-peer (P2P) file sharing applications there has been an increasing interest in understanding the popularity and use of P2P. In this study, we look at P2P use on the University of Southern California's campus network throughout a 14-hour period. We quantify the volume of traffic from P2P activity as well as the number of campus hosts involved in P2P at USC. Since port-matching techniques often fail for P2P applications, we estimate traffic based on both port-based and connection-pattern based techniques. We do not have access to packet data and so these measures provide only bounds on P2P traffic. In addition, while we identify P2P sharing, we can not comment the types of data being shared (either music or data, restricted or freely available). We find that 3-13% of active hosts on campus participate in P2P, and that this traffic accounts for 21-33% of the bytes transferred to and from our campus.
  • datasets: 14 hour monitoring period, from Dec 14th, 2006 at 9pm to Dec 15th at 11am; use USC network traffic captured from two of three commercial provider links at Los Nettos, a regional ISP, and one of two Internet2 links;
  • 3%-13% of active hosts on campus participate in P2P, and that this traffic account for 21%-33% of the bytes transferred to and from campus;
