Measuring Internet One-way Traffic

The presentation will first briefly summarize the findings of a recent large-scale measurement study about one-way traffic in the Internet. Based on the analysis of 7.4 petabytes of traffic observed between 2004 and 2011, our study quantifies the volume and the main causes of one-way traffic. Among a number of interesting observations, it finds that one-way traffic makes a very large fraction, i.e., between 34% and 67%, of the total number of flows to the monitored network, although it only accounts for 3.4% of the number of packets on average, which suggests a new conceptual model for Internet traffic in which one-way traffic is dominant in terms of flows.
