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.

XIA项目旨在设计、评估和实现一个未来的网络架构，该架构提供内在的可信度，支持网络使用模型和网络技术的长期发展，并通过仔细设计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交易对手通信的能力来提供内在安全性。XIA承认通过使用灵活的地址来发展新的使用模式。这种架构灵活性还提供了新的功能，例如，使用户能够在保持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;构建了XIA数据平面，网络协议栈的原型实现，以及使用下一代网络的可扩展性，控制和隔离（SCION）的安全单播通信;从事广泛的基础网络和安全研究;并调查了未来互联网架构研究所提出的问题。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推进XIA的原始愿景，部分原因是在初步调查期间暴露的研究问题。研究议程还包括更加重视基于统一控制平面架构的控制协议。该研究将通过两个挑战架构框架的网络部署来推动：匹兹堡市的车载网络部署和横跨美国的视频交付环境这些部署还利用和深化了安全网络运营方面的工作，包括提供高度可用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如何构建强大的XIA网络，并建立使用XIA架构的最佳实践，包括对移动性和丰富会话层的支持。研究将继续关注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、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将开发用于对未来互联网架构进行比较评估的方法。该评估方法包括定义评估标准，讨论直接和间接评估的重要性，以及使用XIA网络环境和其他用例进行评估。 智力优势：拟议的工作的智力价值是一个雄心勃勃的研究，一个新的架构框架的有效性，在两个具有挑战性的网络环境的背景下进行评估。该团队的跨领域专业知识可以进行广泛而深入的调查，从许多关键网络和安全构建模块的规范和实施开始，直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。评估跨越多个学科，从低级性能评估到对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提出了各种教育和推广活动，以配合拟议的研究。教育活动包括新的白板网络设计课程，以及为代表人数不足的学生和高中生开展的教学和实习活动。更广泛的外联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，该计划由一名曾在联邦通信委员会任职的PI领导。
