2009 Internet Observatory Report

In this paper, we present the largest study of global Internet traffic since the start of the commercial Internet.
We analyze two years of detailed traffic statistics covering 264 Exabytes of Internet traffic across 110 large and geographically diverse cable operators, international transit backbones, regional networks, and content providers.
Our analysis reveals significant changes in the logical topology of the Internet, including the evolution of a new Internet non-tier 1 “core''. Specifically, we show the majority of Internet traffic by volume now flows directly between large content providers, data center/CDNs, and consumer networks.
We also show significant changes in Internet application usage, including a global decline of P2P and a dramatic rise in video traffic.
We conclude with estimates of the current size of the Internet by traffic volume and rate of annualized Internet growth.
