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

表现式互联网架构(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性，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和合理分析多个利益相关者之间的交互(或争点)来解决采用问题。通过向每个实体提供单方面验证其正在与正确的交易对手通信的能力，XIA提供了内在的安全性。夏承认，通过使用灵活的地址，新的使用模式正在演变。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与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步的架构；使用可伸缩性、控制和隔离在下一代网络(SCION)上构建了XIA数据平面、网络协议栈和安全单播通信的原型实现；从事了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提出的问题。在对XIA的下一阶段研究中，主要调查人员(PI)通过深化正在进行的研究推动力来推进XIA的原始愿景，部分原因是在初始调查期间暴露的研究问题。研究议程还包括更加重视基于统一控制平面架构的控制协议。这项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美国各地的视频交付环境。这些部署还利用并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身份验证机制。最后，这些部署需要进一步研究构建强大的XIA网络，并建立使用XIA架构的最佳实践，包括支持移动性和丰富的会话层。这项研究将继续从可部署性和经济可行性的问题中获得信息，并考虑最终用户所感知的XIA。因此，该计划包括关于治理、高可用性的经济影响的研究，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体系结构进行比较评估的方法。该评估方法包括定义评估标准，讨论直接评估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。智力价值：拟议工作的智力价值是对新架构框架的有效性的雄心勃勃的研究，在两个具有挑战性的网络环境的背景下进行评估。该团队的交叉专业知识使我们能够进行广泛和深入的调查，从许多关键网络和安全构建块的规范和实施，到在车辆和视频交付环境中提供创新解决方案的特定应用方法。评价跨越多个学科，从低水平的业绩评价，到对绩效指标量化用户体验的方法的激励兼容性和经济效益的推理。更广泛的影响：该项目将建立一个评估网络体系结构的框架，该框架将广泛适用于国际汽联的研究。私人投资促进机构建议开展各种教育和外展活动，以配合拟议的研究。教育活动包括关于从头开始的网络设计的新课程，以及针对代表性不足和高中生的教学和实习活动。更广泛的外联活动还包括一项计划，由一名曾在联邦通信委员会任职的私家侦探领导，让政策制定者参与并向他们通报当前和未来互联网的健康状况。

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.
