An accurate and exhaustive knowledge of the Internet topology is essential for a deep understanding of such a complex and ever-evolving ecosystem. In this context, a well-known key challenge is represented by alias resolution, i.e. the process of grouping under a unique identifier the addresses owned by the same network layer device. While several(More)
In this work, we propose a methodology based on the alias resolution process to demonstrate that the IP level view of the route provided by traceroute may be a poor representation of the real router-level route followed by the traffic. More precisely, we show how the traceroute output can lead one to (i) inaccurately reconstruct the route by overestimating(More)

An aspect only marginally analyzed in the past is related to the performance of the intra-cloud network connecting the virtual machines (VMs) deployed in the same data center. The few(More)
