NeTS: Small: A Dual-Objective Platform for Internet Experimentation

缺乏对网络的可见性阻碍了许多重要研究领域的进展，从网络故障排除到Internet拓扑和性能映射。虽然这个问题早已被认识到，并成为建立新的或扩展现有实验平台的若干努力的动力，但以足够的规模捕捉互联网的边缘仍然是一个难以实现的目标。问题的根源在于激励机制——在大多数商业互联网中，平台托管者和使用平台的试验者的目标是不一样的。这项工作为互联网实验平台探索了一种新的模式，通过明确地将实验者的目标与拥有有利位置的用户的目标结合起来，解决了激励问题。本研究是在Dasu的背景下进行的，Dasu是一个用于互联网服务提供商表征和互联网实验的系统。这项工作调查了(i)这些类型的平台提供的挑战和机遇，（ii）这些平台如何在保持安全的同时支持易于扩展，以及（iii）如何促进从互联网边缘设计和部署实验，同时减少对两个节点的影响。资源和底层网络。更广泛的影响：这项工作将通过对用户的ISP服务水平的独特观察，为一般互联网社区提供直接的好处。它将产生一套算法、监控协议、软件系统和工具，由于不需要部署和维护额外的基础设施，它们可以立即使用户受益，对整个社会产生重大影响。这项工作将为研究界提供一个能够捕捉商业互联网多样性的实验平台。它将为更好地理解、更透明的互联网做出重大贡献，并为评估部署在互联网边缘的测量技术、工具和网络系统的有效性提供一个急需的测试平台。研究成果和成果将以出版物、数据集和公开发布的软件的形式提供。该项目将对通信、网络和分布式系统方面的教育产生直接影响。

Poor visibility into the network hampers progress in a number of important research areas, from network troubleshooting to Internet topology and performance mapping. While the problem has been long recognized and has served as motivation for several efforts to build new or expand existing experimental platforms, capturing the edge of the Internet at sufficient scale remains an elusive goal. At its roots, the problem is one of incentives - in most of the commercial Internet the goals of those hosting the platform and the experimenters that use it are not the same. This effort explores a new model for Internet experimentation platforms that addresses the incentive problem by explicitly aligning the objectives of the experimenters with those of the users hosting the vantage points. The exploration is done in the context of Dasu, a system for Internet Service Provider characterization and Internet experimentation. The effort investigates (i) the challenges and opportunities offered by these types of platforms, (ii) how such platforms can support easy extensibility while remaining secure, and (iii) how to facilitate the design and deployment of experiments from the Internet edge while reducing the impact on both nodes? resources and the underlying network. Broader Impact: The effort will offer the general Internet community with immediate benefits through a unique view of a user's ISP service levels. It will produce a set of algorithms, monitoring protocols, software systems, and tools that, by not requiring the deployment and maintenance of additional infrastructure, can immediately benefit their users, making a significant impact on society-at-large. The effort will provide the research community with access to an experimentation platform capable of capturing the diversity of the commercial Internet. It will make significant contributions toward a better understood, more transparent Internet and offer a much-needed testbed for evaluating the effectiveness of measurement techniques, tools and networked systems deployed at the edge of the Internet. Research findings and outcomes will be made available as publications, datasets and openly released software. The project will have a direct impact on education in communication, network and distributed systems.
