自30年前现代互联网出现以来,一级互联网服务提供商一直被认为是互联网的骨干,因为它们保证了全球可达性。然而,随着互联网的扁平化减少了对交通服务的需求,增加了私人互联的重要性,它们的影响力和重要性正在减弱。相反,随着越来越多的服务托管在它们的基础设施上,主要的云提供商——亚马逊、bb0、IBM和微软——正变得越来越重要。他们热切支持互联网扁平化,并正在迅速扩大其全球足迹,这使他们能够绕过一级互联网服务提供商和其他大型传输提供商,到达许多目的地。在本文中,我们试图量化云提供商可以绕过一级isp和其他大型传输提供商的程度。我们进行了全面的测量,以确定主要云提供商的邻居网络,并将它们与AS关系推断结合起来,对互联网的AS级拓扑进行建模,以计算一种新的度量,即无层次结构的可达性,该可达性表征了网络在不遍历第一级和第二级isp网络的情况下可以实现的可达性。我们表明,云提供商能够在不穿越第1层和第2层isp的情况下覆盖超过76%的互联网,几乎超过所有其他网络。
The Tier-1 ISPs have been considered the Internet's backbone since the dawn of the modern Internet 30 years ago, as they guarantee global reachability. However, their influence and importance are waning as Internet flattening decreases the demand for transit services and increases the importance of private interconnections. Conversely, major cloud providers -- Amazon, Google, IBM, and Microsoft-- are gaining in importance as more services are hosted on their infrastructures. They ardently support Internet flattening and are rapidly expanding their global footprints, which enables them to bypass the Tier-1 ISPs and other large transit providers to reach many destinations.In this paper we seek to quantify the extent to which the cloud providers' can bypass the Tier-1 ISPs and other large transit providers. We conduct comprehensive measurements to identify the neighbor networks of the major cloud providers and combine them with AS relationship inferences to model the Internet's AS-level topology to calculate a new metric, hierarchy-free reachability, which characterizes the reachability a network can achieve without traversing the networks of the Tier-1 and Tier-2 ISPs. We show that the cloud providers are able to reach over 76% of the Internet without traversing the Tier-1 and Tier-2 ISPs, more than virtually every other network.
