LBNL/ICSI Enterprise Tracing Project

Project Overview

While wide-area Internet traffic has been heavily studied for many years, the characteristics of traffic inside Internet enterprises remain almost wholly unexplored. Nearly all of the studies of enterprise traffic available in the literature are well over a decade old and focus on individual LANs rather than whole sites. A goal of this project is to characterize internal enterprise traffic recorded at a medium-sized site, and to determine ways in which modern enterprise traffic is similar to wide-area Internet traffic, and ways in which it is quite different.

We have collected packet traces that span more than 100 hours of activity from a total of several thousand internal hosts. This wealth of data, which we are publicly releasing in anonymized form, spans a wide range of dimensions.

By releasing these traces we hope to provide a resource for others to use in studying patterns and dynamics within enterprises. Further, we hope that providing a corpus of "background traffic" for security researchers will allow for the sound evaluation of defense mechanisms in the context of the "crud" that appears on real networks.
