Abstract
This study examines the communications networks formed by direct international Internet links, weighted by bandwidth capacity, each year over the 2002–2011 period. Specifically, we analyze changes in bandwidth distributions at country, regional, and continental levels during the period and identify network communities at these different levels. We apply an urn-based model developed with country-level data to bandwidth distributions at regional and continental levels. While the 2011 global Internet network closely resembles that of 2002, the network has become more tightly interconnected over time, and the high international bandwidth regions of Northern Europe, Northern America, and Western Europe have seen a modest decline in their share of total global bandwidth. As a consequence, international bandwidth concentration is showing a slow decline. Relative connectedness as measured by percentage of bandwidth staying within UN geographic regions is decreasing, whereas the percentage remaining within the continent has been fairly constant during the analysis period. All of this must be understood in the context of enormous total international bandwidth growth between 2002 and 2011 at all levels of analysis.
