Abstract
Recent studies show that a significant part of Internet traffic is de-livered through Web-based applications. To cope with the increas-ing demand for Web content, large scale content hosting and de-livery infrastructures, such as data-centers and content distribution networks, are continuously being deployed. Being able to identify and classify such hosting infrastructures is helpful not only to con-tent producers, content providers, and ISPs, but also to the research community at large. For example, to quantify the degree of hosting infrastructure deployment in the Internet or the replication of Web content. In this paper, we introduce Web Content Cartography, i. e., the identification and classification of content hosting and delivery in-frastructures. We propose a lightweight and fully automated ap-proach to discover hosting infrastructures based only on DNS mea-surements and BGP routing table snapshots. Our experimental re-sults show that our approach is feasible even with a limited num-ber of well-distributed vantage points. We find that some popular content is served exclusively from specific regions and ASes. Fur-thermore, our classification enables us to derive content-centric AS rankings that complement existing AS rankings and shed light on recent observations about shifts in inter-domain traffic and the AS topology.
