IRNC: SP: 6Watch: Routeviews Infrastructure for Monitoring, Tracking and Diagnosing IPv6 Deployment

该项目旨在开发一个全球范围的IPv6监测系统，该系统将跟踪IPv6地址分配、IPv6路由公告、支持IPv6的网络的拓扑连通性以及数据平面中的IPv6可达性。这些指标中的每一个都有助于跟踪IPv6部署，但控制平面指标和数据平面指标的正确组合有可能提供IPv6部署成功和障碍的全面概述。将应用在监测IPv4基础设施方面吸取的经验教训，但监测IPv6部署带来了许多独特的挑战和未知因素。在IPv6部署的早期阶段，提供可以补充控制平面信息的数据平面信息尤为重要。该项目将开发一种创新技术，通过使用主动探测DNS服务器来测量IPv6覆盖范围和可达性。这种方法利用了我们现有的DNS监控基础设施，使我们能够在IPv6-IPv6和IPv6-IPv4场景中测试可达性。如果成功，结果将为面临特定测量问题的研究人员和运营商提供详细信息，并为那些寻找IPv6部署挑战的人提供有意义的全球视角。调查结果不仅将提供IPv6部署的最新快照，还将有助于确定开放问题和潜在障碍，以促进IPv6部署。

This project is to develop a global scale IPv6 monitoring system that will track IPv6 address allocations, IPv6 routing announcements, the topological connectivity of IPv6-capable networks, and IPv6 reachability in the data plane, all at the global scale. Each of these metrics is useful in tracking IPv6 deployment, but the right combination of control plane metrics and data plane metrics has the potential to provide a comprehensive overview of IPv6 deployment successes and obstacles. Lessons learned in monitoring IPv4 infrastructure will be applied, but monitoring IPv6 deployment poses a number of unique challenges and unknowns. At this early stage of IPv6 deployment, it is particularly important to provide data plane information that can complement the control plane information. This project will develop an innovative technique that measures IPv6 coverage and reachability by using active probes to DNS servers. This approach leverages our existing DNS monitoring infrastructure and will allow us to test reachablity in both IPv6-IPv6 and IPv6-IPv4 scenarios. If successful, the results will provide detailed information for researchers and operators faced with specific measurement questions and also provide a global perspective that is meaningful to those searching for IPv6 deployment challenges. The results will not only provide the latest snapshot of IPv6 rollout but will also help identify open issues and potential obstacles to facilitate IPv6 deployment.
