FIA-NP: Collaborative Research: Named Data Networking Next Phase (NDN-NP)

命名数据网络(NDN)是一种未来的互联网体系结构，其灵感来自对网络使用的多年经验研究和对IP中未解决问题的日益认识。其前提是，互联网主要用作信息分发网络，与IP不是很好的匹配，未来互联网的“瘦腰”应该基于命名的数据，而不是数字寻址的主机。这项提案延续了美国国家科学基金会FIA计划于2010年开始的研究。它将主要研究人员(PI)对NDN机遇和挑战的日益了解应用于两个国家优先事项--卫生信息技术和网络物理系统--以实验方式进一步发展已被证明成功的体系结构。组织研究议程是为了将体系结构和安全方面的关键成果转化为库代码，以指导应用程序开发以实现本地NDN设计。NDN的研究议程包括：1)应用程序--探索命名和应用程序设计模式；会合、发现和自举；网络内存储的设计；以及新的同步原语的使用；2)安全与可信性--提供密钥管理、信任管理和基于加密的访问控制的基本构件，并预测未来的安全挑战；3)路由和转发策略--开发和评估域间路由的路径向量、链路状态和双曲线选项，解决路由安全性和信任度问题，并设计快速转发和移动性支持；4)可扩展转发--旨在通过可操作、可扩展的转发平台支持实际部署、评估和采用；5)库和工具--根据团队的基本结果开发参考实现；6)社会和经济影响--考虑目标环境的具体问题和“无障碍网络世界”中出现的更广泛的问题。PI选择移动健康和企业建筑自动化及管理系统作为特定环境，以验证架构并推动新的研究。该领域的专家将是1)Open mHealth，这是一个由Deborah Estrin(康奈尔大学)和Ida Sim(加州大学旧金山分校)领导的非营利性以患者为中心的生态系统；以及2)UCLA设施管理公司，是西海岸第二大西门子建筑监控系统的运营商。为了更广泛地指导对这些环境和NDN的安全维度的研究，NDN团队召集了一个安全咨询委员会来补充自己的努力。智力上的优点：NDN建立在从IP的成功中吸取的经验教训的基础上，保留了瘦腰、分层命名和端到端原则。该设计认识到应用程序通信模型的主要转变，从“在哪里”(即，主机/位置)到“什么”(即，内容)。围绕这一转变构建通信基础设施可以从根本上简化应用程序设计，使他们能够使用他们想要的内容名称直接通信，并让网络来确定如何检索以及从哪里检索。NDN还认识到当前互联网架构中最大的弱点是缺乏安全性，并采用了一个基本的构建块来通过要求所有内容签名来提高安全性。博主影响：新架构的成功需要社区的参与和接受。NDN通过致力于开放源码模型建立了势头，该模型在架构和当前实现方面都刺激了大量的研究活动。项目成员经常被邀请在世界各地的“未来互联网”会议上发言，而PI们已经展示了NDN处理大规模分发的能力的高可见度演示。工业界也表现出越来越多的参与。最后，NDN对学生产生了重大影响，产生了几篇博士论文、相关的行业实习以及研究生和本科生课程，这些课程现在可以提供IP的全面替代方案，以激发关于网络架构设计真正含义的讨论。

Named Data Networking (NDN) is a Future Internet Architecture inspired by years of empirical research into network usage and a growing awareness of unsolved problems in IP. Its premise is that the Internet is primarily used as an information distribution network, which is not a good match for IP, and that the future Internet's "thin waist" should be based on named data rather than numerically addressed hosts. This proposal continues research started in 2010 under NSF's FIA program. It applies the principal investigators' (PIs) increasing understanding of NDN opportunities and challenges to two national priorities--Health IT and Cyber-physical Systems--to further evolve the architecture in the experimental manner that has proven successful. The research agenda is organized to translate key results in architecture and security into library code that guides application development towards native NDN designs. It simultaneously continues fundamental research into the challenges of global scalability and opportunities for innovation created by "simply" routing and forwarding data based on names.The NDN research agenda includes: 1) Applications--exploring naming and application design patterns; rendezvous, discovery and bootstrapping; the design of in-network storage; and use of new synchronization primitives; 2) Security & trustworthiness--providing basic building blocks of key management, trust management, and encryption-based access control, and anticipating future security challenges; 3) Routing and forwarding strategy--developing and evaluating path-vector, link-state, and hyperbolic options for inter-domain routing, addressing routing security and trust, and designing fast forwarding and mobility support; 4) Scalable forwarding--aiming to support real-world deployment, evaluation and adoption via an operational, scalable forwarding platform; 5) Libraries & tools--developing reference implementations based on the team's fundamental results; 6) Social & economic impacts--considering specific questions of the target environments and broader ones arising in a "World on NDN." The PIs choose Mobile Health and Enterprise Building Automation & Management Systems as specific environments to validate the architecture and drive new research. Domain experts will be 1) Open mHealth, a non-profit patient-centric ecosystem led by Deborah Estrin (Cornell) and Ida Sim (UCSF); and 2) UCLA Facilities Management, operators of the second largest Siemens building monitoring system on the West Coast. To guide research on the security dimensions of these environments and NDN more generally, the NDN team has convened a Security Advisory Council to complement its own effort.Intellectual Merit: NDN builds on lessons learned from the success of IP, preserving the thin waist, hierarchical naming, and end-to-end principles. The design recognizes the major shift in the applications communication model, from the "where" (i.e., the host/location) to the "what" (i.e., the content). Architecting a communications infrastructure around this shift can radically simplify application designs, enabling them to communicate directly using content names they desire and leaving it to the network to figure out how and from where to retrieve it. NDN also recognizes that the biggest weakness in the current Internet architecture is lack of security, and incorporates a fundamental building block to improve security by requiring that all content be signed.Broader Impacts: The success of new architectures requires community involvement and uptake. NDN has built momentum through a commitment to an open source model that has spurred substantial research activity in both architecture and current implementation. Project members are often invited to present at "future Internet" meetings around the world, and the PIs have performed high-visibility demos of NDN's ability to handle large scale distribution. Industry is also showing increasing participation. Finally, NDN has significantly impacted students, generating several Ph.D. theses, related industry internships, and both graduate and undergraduate classes that can now present a comprehensive alternative to IP to stimulate discussion of what network architecture design really means.
