FIA-NP: Collaborative Research: Deployment-Driven Evaluation and Evolution of the eXpressive Internet Architecture

表达互联网架构（XIA）项目旨在设计、评估和实现未来的网络架构，该架构提供固有的可信度，支持网络使用模型和网络技术的长期演进，并通过精心设计api和对多个利益相关者之间的交互（或争论点）进行合理分析来解决采用问题。XIA通过为每个实体提供单方面验证其与正确的对手方通信的能力来提供内在安全性。XIA允许通过使用灵活地址来发展新的使用模式。这种架构灵活性还暴露了一些新特性，例如，允许用户在维护匿名性和最大化内容检索效率之间进行权衡。到目前为止，XIA团队已经开发了一个初始架构；构建XIA数据平面的原型实现，网络协议栈，以及在下一代网络（SCION）上使用可扩展性，控制和隔离的安全单播通信；从事广泛的基础网络和安全研究；并对未来互联网架构研究提出的问题进行了探讨。在XIA的下一阶段研究中，主要研究者（pi）通过深化正在进行的研究重点来推进XIA的最初愿景，部分原因是在初始调查期间暴露的研究问题。研究议程还包括增加对基于统一控制平面架构的控制协议的重视。该研究将通过两个网络部署来推动，这两个网络部署对架构框架提出了挑战：匹兹堡市的车辆网络部署和跨越美国的视频传输环境。这些部署还利用并深化了安全网络运营的工作，包括提供高可用性的基础设施和安全认证机制。最后，这些部署需要进一步研究构建健壮的XIA网络，并建立使用XIA体系结构的最佳实践，包括对移动性和丰富会话层的支持。研究将继续考虑可部署性和经济可行性问题，并考虑最终用户对XIA的看法。因此，该计划包括对治理的研究、高可用性的经济影响，以及调查隐私、透明度和用户控制之间相互作用的用户研究。最后，pi将开发对未来互联网架构进行比较评估的方法。该评估方法包括评估标准的定义、对直接和间接评估重要性的讨论，以及使用XIA网络环境和其他用例进行评估。智力价值：所建议的工作的智力价值是对新架构框架的有效性进行了雄心勃勃的研究，并在两个具有挑战性的网络环境中进行了评估。从许多关键网络和安全构建模块的规范和实施，到在车辆和视频传输环境中提供创新解决方案的特定应用方法，该团队的跨领域专业知识能够进行广泛而深入的调查。评估跨越多个学科，从低水平的绩效评估到对pi方法的激励兼容性和经济效益的推理，再到用户体验的量化。更广泛的影响：该项目将建立一个评估网络架构的框架，该框架将广泛适用于FIA研究。pi建议各种教育和外展活动，以配合拟议的研究。教育活动包括全新的网络设计课程，以及针对弱势群体和高中生的教学和实习活动。更广泛的外展活动还包括一项计划，让决策者参与并了解当前和未来互联网的健康状况，该计划由曾在联邦通信委员会任职的PI领导。

The eXpressive Internet Architecture (XIA) project aims to design, evaluate, and realize a future network architecture that provides inherent trustworthiness, supports long-term evolution of network use models and network technology, and addresses adoption through careful design of APIs and reasoned analysis of interactions (or tussle points) between multiple stakeholders. XIA offers intrinsic security by offering each entity the ability to unilaterally validate that it is communicating with the correct counterparties. XIA admits new usage models to evolve through the use of flexible addresses. This architectural flexibility also exposes new features, for example, enabling users to trade-off maintaining anonymity against maximizing efficiency in content retrieval. To date, the XIA team has developed an initial architecture; built prototype implementations of the XIA data plane, network protocol stack, and secure unicast communication using Scalability, Control and Isolation On next-generation Networks (SCION); engaged in a wide range of basic networking and security research; and investigated questions raised by future Internet architecture research.In the next phase of research on XIA, principal investigators (PIs) advance the original vision of XIA by deepening the ongoing research thrusts, driven in part by research questions exposed during the initial investigation. The research agenda also includes an increased emphasis on control protocols based on a unified control plane architecture. The research will be driven through two network deployments that challenge the architectural framework: a vehicular network deployment in the city of Pittsburgh, and a video delivery environment spanning the U.S. These deployments also leverage and deepen the work on secure network operations, including providing a highly available infrastructure and secure authentication mechanisms. Finally, these deployments necessitate further research on building a robust XIA network, and establish best practices for using the XIA architecture, including support for mobility and a rich session layer. The research will continue to be informed by issues of deployability and economic viability, and to consider XIA as perceived by end users. The plan therefore includes research on governance, economic implications of high availability, and user studies that investigate the interplay between privacy, transparency and user control. Finally, the PIs will develop methods for performing a comparative evaluation of future Internet architectures. This evaluation methodology includes a definition of evaluation criteria, a discussion of the importance of direct and indirect evaluation, and evaluation using the XIA network environments and other use cases. Intellectual Merit: The intellectual merit of the proposed work is an ambitious study of the effectiveness of a new architectural framework, evaluated in the context of two challenging network environments. The cross-cutting expertise of the team enables broad and deep investigation, starting from specification and implementation of many key network and security building blocks, up to application-specific methods delivering innovative solutions in the vehicular and video delivery environments. The evaluation spans multiple disciplines, ranging from low-level performance evaluation to reasoning about incentive-compatibility and economic benefits of the PIs' approach to a quantification of user experience. Broader Impacts: The project will establish a framework for evaluating network architectures that will be broadly applicable to FIA research. The PIs propose a variety of education and outreach activities to accompany the proposed research. Educational activities include new courses on clean-slate network design, and teaching and internship activities for under-represented and high school students. Broader outreach activity also includes a plan to involve and inform policymakers on the health of the current and future Internet led by a PI who formerly served at the FCC.
