Enterprise Network Traffic Analysis

Vern Paxson and Mark Allman1

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. In this project we study an extensive set of traces (spanning several hundred hours) of network traffic recorded inside an enterprise with several thousand hosts. One particular question of interest is the degree to which, and reasons why, hosts on the network consume power in the absence of user activity, and how we might architect enterprise networks to minimize such consumption.
