Traffic growth analysis over three years in enterprise networks

Abstract

The increasing popularity of P2P and multimedia applications around the world has resulted in significant global increases in network traffic. This paper investigates the traffic changes in our enterprise network by analyzing the day-long traffic traces from 2007 to 2009. We observe that there has been a substantial increase in traffic in the past few years; however, no single application type is a dominant cause. This paper analyzes the following categories: Traffic volume, flow characteristics and protocol usage, and the use of IP address space.
