“…We observe that this subset is much larger and coarsegrained compared to the mapping generated by Nautilus. iGDB [45] is the first framework that supports cross-layer mapping of the Internet, but it is restricted to terrestrial cables. iGDB maps potential land cable end points by dividing urban areas using Thiessen polygons and identifying potential cables between them.…”

“…Past work on Internet mapping was largely confined to specific layers of the Internet and did not support crosslayer mapping [50,75]; for example, mapping of physical cables [52,70,71], interfaces [44,59,82,83], routers [62,67,73,74], PoPs [53,64,79,81], and ASes [43,48,78]. Recently, iGDB [45] put forward the first cross-layer mapping framework for the Internet. But iGDB does not currently support cross-layer mapping over transoceanic paths.…”

“…al. (which we call SCN-Crit from here on) [65] and iGDB [45] extended to submarine cables. We show that Nautilus generates a more accurate mapping to a fewer set of cables (35% and 75% fewer cables compared to SCN-Crit and iGDB, respectively).…”

Submarine cables constitute the backbone of the Internet. However, these critical infrastructure components are vulnerable to several natural and man-made threats, and during failures, are difficult to repair in their remote oceanic environments. In spite of their crucial role, we have a limited understanding of the impact of submarine cable failures on global connectivity, particularly on the higher layers of the Internet.In this paper, we present Nautilus, a framework for crosslayer cartography of submarine cables and IP links. Using a corpus of public datasets and Internet cartographic techniques, Nautilus identifies IP links that are likely traversing submarine cables and maps them to one or more potential cables. Nautilus also gives each IP to cable assignment a prediction score that reflects the confidence in the mapping. Nautilus generates a mapping for 3.05 million and 1.42 million IPv4 and IPv6 links respectively, covering 91% of all active cables. In the absence of ground truth data, we validate Nautilus mapping using three techniques: analyzing past cable failures, using targeted traceroute measurements, and comparing with public network maps of two operators.

A resilient Internet infrastructure is critical in our highly interconnected society. However, the Internet faces several vulnerabilities, ranging from natural disasters to human activities, that can impact the physical layer and, in turn, the higher network layers, such as IP links. In this paper, we introduce Xaminer, the first Internet cross-layer resilience analysis tool, to evaluate the interplay between physical- and network-layer failures. Using a cross-layer Internet map and a failure event model, Xaminer generates a risk profile encompassing a cross-layer impact report, critical infrastructure identification at each layer, and the discovery of trends and patterns under different failure event settings. Xaminer's key strengths lie in its adaptability to diverse disaster scenarios, the ability to assess risks at various granularities, and the capability to generate joint risk profiles for multiple events. We demonstrate Xaminer's capabilities in cross-layer analysis across a spectrum of disaster event models and regions, showcasing its potential role in facilitating well-informed decision-making for resilience planning and deployments. The Xaminer tool is available as open-source software.
