项目摘要

Maps of the interconnections between pairs of networks or Autonomous Systems (ASes), such as Internet providers, are important to a wide range of parties, such as network researchers and network operators, whose activities depend on an accurate view of the Internet and its interconnections. Systematically mapping these interconnections is known to be a notoriously difficult problem. Here, the term 'mapping' refers to first inferring the presence and type of interconnections (e.g., public vs. private peering) and then geolocating them to the colocation facility where the interconnections are provided and utilized. Recently, the introduction of and growing demand for "virtual private interconnections" (VPIs) has been particularly disruptive for any such mapping efforts. VPIs are a new interconnection service that is offered at newly emerging infrastructures called "cloud exchanges" that some of the major colocation facility providers (e.g., Equinix and CoreSite) have started to operate in their major markets. By offering VPIs, these cloud exchanges enable traditional players (e.g., networks operating with an AS number) as well as non-traditional players (e.g., enterprises that do not own an AS number) to connect to any cloud provider that is present at the exchange, thereby enabling cloud-service-related traffic to bypass the public Internet. Moreover, in contrast to the traditional interconnection options, VPIs can be provisioned in real-time via the use of web-based portals. The ability of a large pool of non-traditional Internet players to establish interconnections in the form of VPIs and the increasingly dynamic nature of this type of interconnection have made the systematic mapping of today's Internet interconnections even more challenging. Not only are the existing techniques for mapping Internet interconnections incapable of detecting VPIs, but even when applied to the traditional types of interconnections, their applicability and accuracy remain largely unknown. As more networks utilize cloud services, the concurrent use of traditional interconnections and cloud-exchange-provided VPIs is becoming more common and requires a new approach for discovering this 'hybrid' connectivity, studying its dynamics, and providing a first-of-its-kind assessment of the type of 'service-to-service' connectivity that is fueled by the 'cloudification' of today's Internet. The main goal of this research project is to develop such a new approach and design and rigorously evaluate the resulting suite of new techniques and open-source tools for inferring and geolocating interconnections in general, and VPIs at both cloud exchanges and certain IXPs (Internet eXchange Points), in particular. An online portal that offers useful visualization capabilities and provides access to a large archive of geo-aware interconnection maps will be developed as part of this project. The project will also enable other research groups to contribute to this important mapping effort, encourage the cross-validation of results by different research groups, and ultimately produce more accurate maps of the Internet's interconnections that can be expected to offer unique insights into new ways of detecting potential Internet vulnerabilities and performance bottlenecks. The project is complemented by an education and outreach plan that includes (i) the development of a curriculum for a new course and graduate level seminars, (ii) the participation of Masters level and undergraduate students in the proposed work (e.g., measurement, visualization), and (iii) the organization of a K-12 outreach activity where CS students volunteer to teach basic programming concepts to students at local elementary, middle, and high schools as part of after-school programs.

互联网提供商（例如互联网提供商）对网络或自主系统（ASE）之间互连的地图对各种政党（例如网络研究人员和网络运营商）很重要，例如网络研究人员和网络运营商，其活动取决于对互联网及其互连的准确看法。系统地绘制这些互连是一个众所周知的困难问题。在这里，“映射”一词是指首先推断互连的存在和类型（例如，公共与私人对等），然后将它们拨打到提供和利用互连的托管设施中。最近，引入对“虚拟私人互连”（VPI）的需求不断增长，这对于任何此类映射工作尤其令人破坏。 VPI是一种新的互连服务，该服务在新兴新兴的基础设施中提供，称为“云交换”，某些主要的托管设施提供商（例如Equinix和Coresite）已开始在其主要市场中运营。通过提供VPI，这些云交换使传统参与者（例如，以AS数字为单位运行的网络）以及非传统参与者（例如，不拥有AS数字的企业）可以连接到Exchange中存在的任何云提供商，从而启用与云相关的流量，以绕过公共Internet。此外，与传统的互连选项相反，可以通过使用基于Web的门户实时提供VPI。大量非传统互联网参与者以VPI的形式建立互连以及这种类型的互连的动态性质的能力使当今的互联网互连的系统映射更加具有挑战性。不仅绘制互联网互连的现有技术无法检测到VPI，而且即使应用于传统类型的互连类型，它们的适用性和准确性仍然在很大程度上未知。随着越来越多的网络利用云服务，传统的互连和云交换提供的VPI的同时使用变得越来越普遍，并且需要一种新的方法来发现这种“混合”连接，研究其动态，并提供了对“服务对台服务”的连接类型的首次评估，从而促进了“ clul Cluligedy”的互联网。该研究项目的主要目标是开发这种新方法和设计，并严格评估所得的新技术和开源工具，用于推断和地理位置一般的互连，以及在云交换和某些IXPS（互联网交换点）的VPI，尤其是。在线门户网站提供有用的可视化功能，并提供对大型地理意识互连图的大量档案的访问权限，作为该项目的一部分。该项目还将使其他研究小组能够为这项重要的映射工作做出贡献，鼓励不同研究小组的结果交叉验证，并最终产生更准确的互联网互连地图，这些图可以预期，可以为检测潜在的互联网漏洞和性能效果的新方法提供独特的见解。 The project is complemented by an education and outreach plan that includes (i) the development of a curriculum for a new course and graduate level seminars, (ii) the participation of Masters level and undergraduate students in the proposed work (e.g., measurement, visualization), and (iii) the organization of a K-12 outreach activity where CS students volunteer to teach basic programming concepts to students at local elementary, middle, and high schools as part of课后课程。
