However, limitations of public data sources in detecting settlement-free peering links meant that prior work focused almost exclusively on transit links. In this work, we explore the possibility of studying the full connectivity of a small set of ASes, which we call usable monitors. Usable monitors, while a subset of the ASes that provide BGP feeds to Routeviews/RIPE collectors, are better suited to an evolutionary study than other ASes.We propose CMON, an algorithm to classify the links of usable monitors as transit or non-transit. We classify usable monitors as transit providers (large and small), content producers, content consumers and education/research networks. We highlight key differences in the evolution of connectivity of usable monitors, and measure transitions between different relationships for the same pair of ASes. %G English %Z TC 6 %2 https://inria.hal.science/hal-01531958/document %2 https://inria.hal.science/hal-01531958/file/978-3-642-30054-7_11_Chapter.pdf %L hal-01531958 %U https://inria.hal.science/hal-01531958 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC6 %~ IFIP-LNCS-7290 %~ IFIP-NETWORKING
