Launched in 2005 and released to the public in 2006, Google Earth fast became a household name hailed as a revolution for humanitarian development, much as Geographic Information Systems (GIS) were several decades ago. According to MapAction, “There seem at present tobe two distinct groups of humanitarian practitioners: those who are already, albeit tentatively,exploiting Google Earth and related geospatial methods in their work,and those whowill be, as soon as they see their first demonstration of its potential.” (MapAction, 2008: 9)

The rapid advent of “Web 2.0” applications has unleashed new HTTP traffic patterns which differ from the conventional HTTP request-response model. In particular, asynchronous pre-fetching of data in order to provide a smooth web browsing experience and richer HTTP payloads (e.g., Javascript libraries) of Web 2.0 applications induce larger, heavier, and more bursty traffic on the underlying networks. We present a traffic study of Web 2.0 applications including Google Maps, modern Web-email, and social networking Web sites, and compare them with all HTTP traffic. We highlight the key differences of Web 2.0 traffic from traditional HTTP traffic through statistical analysis. As such our work elucidates the changing face of one of the most popular application on the Internet: The World Wide Web.
