CNS Core: Medium: Collaborative Research: Strategies for Large-Scale IPv6

网络研究界在衡量互联网协议版本6(IPv6)可寻址互联网的采用率、性能和安全方面投入了大量精力，该可寻址互联网最初旨在取代当前的互联网协议版本4(IPv4)互联网，以满足互联网增长和使用的持续需求。然而，IPv6测量技术在很大程度上反映了当前IPv4互联网的测量技术，其覆盖范围和效率可能令人失望。许多科学、工程和操作问题需要新的测量方法，明确考虑IPv6协议、实施和操作部署的独特属性。该项目的目标是全面、普遍、准确和可用的测量能力，重点是IPv6互联网地图绘制，并与广泛的科学研究人员共享测量工具和数据。该项目将严格调查、开发和评估应对特定于IPv6的挑战的大规模IPv6主动映射(SLAM)策略：可将覆盖范围扩大数量级的测量策略；推断路由器级别拓扑的特定于IPv6的算法的创新；以及分析和补救关键通信基础设施的弹性、安全和隐私风险。要将这一能力用于科学研究，将需要改进技术以支持分布式部署，将探测与响应收集分离，纳入更多情报，并扩展效率和性能。这项新技术的应用将包括尝试绘制移动提供商的IPv6基础设施图，这是IPv6采用的驱动力。由此产生的数据将有助于解决IPv6采用悖论，重点是使用科学测量的实际全球IPv6可达性。这项研究还将支持持续的运营挑战，包括检测IPv6路由劫持和IPv6基础设施的地理位置。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The networking research community has invested significant efforts into measuring adoption, performance, and security aspects of the Internet Protocol version 6 (IPv6)-addressable Internet, originally designed to replace the current Internet Protocol version 4 (IPv4) Internet to meet the relentless demand for Internet growth and usage. However, IPv6 measurement techniques have largely mirrored those of the current IPv4 Internet, which can yield disappointing coverage and efficiency. Many scientific, engineering, and operational questions require new measurements that explicitly consider unique properties of the IPv6 protocol, implementations, and operational deployment. The project goals target comprehensive, pervasive, accurate, and usable measurement capabilities, focused on IPv6 Internet cartography, and sharing measurement tools and data with a broad range of scientific researchers.This project will rigorously investigate, develop, and evaluate Strategies for Large-Scale IPv6 Active Mapping (SLAM) that meet IPv6-specific challenges: measurement strategies that can amplify our coverage by orders of magnitude; innovations in IPv6-specific algorithms to infer router-level topologies; and analysis and remediation of resiliency, security, and privacy risks to critical communications infrastructure. Operationalizing this capability for use in scientific research will require refining the technique to support distributed deployment, decouple probing from response collection, incorporate additional intelligence, and scale efficiency and performance. Application of the new technique will include an attempt to map the IPv6 infrastructure of mobile providers, a driver of IPv6 adoption. The resulting data will help resolve the IPv6 adoption paradox, with a focus on actual global IPv6 reachability using scientific measurements. This research will also support persistent operational challenges, including detection of IPv6 route hijacks, and geolocation of IPv6 infrastructure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
