Overview

This website goal is to examine the role of the Content Providers in the AS ecosystem after the widespread growth of private CDNs. There is recent evidence that the core of the Internet, which was formerly dominated by large Transit Providers, has been reshaped after the transition to a multimedia-oriented network, first by general-purpose CDNs and now by private CDNs, the so-called flattening of the Internet topology.0 To do so, this website based its methodology on k-cores, an element of graph theory, to define which ASes compose the core of the network and to track the evolution of the core since 1999. Applying the k-cores technique this website provides two services: i) a graph gallery to visualize the core evolution of big players throughout the years ii) an interactive analysis of our datasets to detect, for example, ``up and coming'' ASes using customized queries.
