The state of enterprise network traffic in 2012

Timely and accurate studies on the composition and nature of the Internet are crucial for continued research and innovation. The aim of this research is to aid and service emulated and simulated research methods where realism is dependent on the accuracy of Internet statistics. This study has captured anonymised, and analysed Internet traffic entering and exiting a university network. Passive measurement techniques are used to discover the mean and distribution of packet sizes. A range of Network and Transport layer statistics, such as DCSP, SACK, ECN, MSS usage, Window Scaling and Timestamps are also investigated. Active measurement techniques are used to determine Round Trip Times (RTTs) and the number of lost and misordered packets. Prior work is leveraged to explore changes in the composition and nature of the Internet over the last 10 years.
