摘要：
海底电缆是互联网的骨干。然而，这些关键基础设施组件易受多种自然和人为威胁的影响，且发生故障时，在偏远的海洋环境中难以修复。尽管它们作用至关重要，但我们对海底电缆故障对全球连通性、尤其是对互联网更高层的影响了解有限。\n 本文提出了Nautilus，一个用于海底电缆与IP链路跨层制图的框架。借助公共数据集语料和互联网制图技术，Nautilus可识别可能经由海底电缆传输的IP链路，并将其映射到一条或多条潜在电缆上。Nautilus还会为每个IP到电缆的分配赋予一个预测分数，以反映该映射的置信度。Nautilus分别为305万条IPv4链路和143万条IPv6链路生成了映射，覆盖91%的在用电缆。在缺乏真值数据的情况下，我们通过三种技术验证Nautilus的映射：分析过往的电缆故障、使用定向traceroute测量，以及与两家运营商的公共网络地图进行对比。
英文摘要：
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 cross-layer 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 1.43 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.
