AB Lots of studies about the Internet Autonomous System (AS) level topology have been carried out during the last twenty years, most of them analyzing this topology on a world-wide scale, a lot of them based on routing information from the Border Gateway Protocol (BGP). However, studies focusing on a specific region and making comparisons between regions are not that popular and in fact, most world-wide studies are not valid in some particular regions. This work is targeting this particular problem of the regional or country topology analysis by enhancing regular AS-level graphs where to apply different connectivity metrics. The focus is set on Latin America and the Caribbean (the LAC region) which exhibits appropriate conditions for this type of analysis and where we show that a basic metric comparison may not be good enough so as to realize that there is a connectivity problem in the region. After concluding that the situation in the LAC region in terms of interconnection is even worse than expected, we perform some country-level studies finding correlations between graph characteristics and some socioeconomic indicators. We then use these correlations to identify countries in which it would be worth pushing for the deployment of an Internet Exchange Point (IXP), as simulating the creation of an IXP there has a great impact on the interconnection level and on the robustness of the regional Internet.
