最近有证据表明，互联网的核心，这是以前占主导地位的大型运输供应商，已被重塑后，过渡到面向多媒体的网络，首先是通用的CDN，现在是私有CDN。在这项工作中，我们使用k-cores，图论的一个元素，来定义哪些AS构成互联网的核心，并跟踪自1999年以来核心的演变。具体来说，我们调查了互联网内容和CDN生态系统中的大型参与者是否属于核心，如果是，从什么时候开始。此外，我们还研究了IPv4和IPv6内核之间的差异。我们进一步研究了大型内容提供商演变的区域差异。最后，我们表明，近年来，互联网的核心已经纳入了越来越多的内容AS。为了使这项工作的可重复性，我们提供了一个网站，允许我们的数据集进行交互式分析，以检测，例如，使用自定义查询的“即将到来的”AS。
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. In this work we usek-cores, an element of graph theory, to define which ASes compose the core of the Internet and to track the evolution of the core since 1999. Specifically, we investigate whether large players in the Internet content and CDN ecosystem belong to the core and, if so, since when. In addition, we examine differences between the IPv4 and IPv6 cores. We further investigate regional differences in the evolution of large content providers. Finally, we show that the core of the Internet has incorporated an increasing number of content ASes in recent years. To enable reproducibility of this work, we provide a website to allow interactive analysis of our datasets to detect, for example, “up and coming” ASes using customized queries.
