Variable Heavy Tail Duration in Internet Traffic

by F. Hernández-Campos, J. S. Marron, G. Samorodnitsky and F. D. Smith

The plots shown here are an expanded set of results for the following paper:

F. Hernández-Campos, J. S. Marron, G. Samorodnitsky and F. D. Smith, Variable Heavy Tails in Internet Traffic. (PostScript Version) (PDF Version) To appear in the Journal of Performance Evaluation.

In order to match conference page requirements, this paper was splitted into two parts:

• F. Hernández-Campos, J. S. Marron, G. Samorodnitsky and F. D. Smith, Variable Heavy Tail Duration in Internet Traffic, Part I: Understanding Heavy Tails. (PostScript Version) (PDF Version) A slightly shorter version of this paper appeared in the proceedings of IEEE MASCOTS'02, October, 2002 (PostScript Version) (PDF Version)

The data for these plots are extracted from empirical datasets obtained by tracing TCP/IP packet headers. These traces were created by recording the TCP/IP header of each packet flowing on the network link connecting the UNC Chapel Hill campus to the Internet over 4-hour intervals. A timestamp (with microsecond resolution) was also recorded for each header along with the length in bytes of the packet. All of the traces studied in this paper are from the same week in April, 2001. Additional details on the data collection and processing methods can be found in:

F.D. Smith, F. Hernández-Campos, K. Jeffay, and D. Ott, What TCP/IP Protocol Headers Can Tell Us About the Web, Proceedings of ACM SIGMETRICS 2001/Performance 2001, Cambridge, MA, June 2001, pages 245-256. (PDF Version)

The data shown in the plots represent the network transfer times for fetching web objects (HTML pages, embedded images, etc.) by browsers (Netscape or Internet Explorer) used on the UNC-Chapel Hill campus.

The visualizations are organized in groups ordered to match the order of presentation in the original paper. Each group label below is a link to where that group can be found in this page.
