Anatomy of Public Internet eXchange Points Ecosystem in Brazil

For a long time many efforts were carried to increase the understanding of the complex Internet ecosystem. Internet eXchange Points have been targets since they represent a microcosm of Internet diversity. The contribution of this paper is the first empirical analysis of the IXP ecosystem in Brazil, compiling information that comprehend the characterization of members participating of these environments, including the build of AS-level connectivity graphs. By analysing the topologies we found the average adjacency of IXP's members (vertices degree), the isolated and accumulated depth of paths in advertised routes (AS-PATH), the density of peers to highlight the peering potential within IXPs, the accounting of traffic engineering policies related to AS-Prepend and k-clique communities. Another contribution is that our dataset with more than 2.5 GB is shared with the academic community.
