FIA: Collaborative Research: Named Data Networking (NDN)

虽然互联网远远超出了预期，但它也夸大了最初的假设，经常引发争执，挑战其基本的沟通模式。用户和应用程序根据内容进行操作，这使得通过发现和指定位置来满足IP的通信要求变得越来越有限和困难。为了将互联网带到未来，需要一个概念上简单但具有变革性的架构转变，从今天的焦点转向哪里？地址和主机？为了什么？用户和应用程序关心的内容。这个项目调查了一种潜在的新的互联网体系结构，称为命名数据网络(NDN)。NDN利用自己的优势？并解决了弱点？互联网目前以主机为基础的点对点通信架构，以便自然地适应新兴的通信模式。通过命名数据而不是它们的位置，NDN将数据转换为一流的实体。当前的互联网确保了数据容器的安全。NDN保护内容，这是一种将对数据的信任与对主机的信任分离的设计选择，支持几种可从根本上扩展的通信机制，如自动缓存以优化带宽。该项目研究了验证NDN作为未来Internet体系结构必须解决的技术挑战：路由可伸缩性、快速转发、信任模型、网络安全、内容保护和隐私以及基本通信理论。该项目使用端到端试验台部署、模拟和理论分析来评估所提出的体系结构，并正在开发NDN协议和应用的规范和原型实现。

While the Internet has far exceeded expectations, it has also stretched initial assumptions, often creating tussles that challenge its underlying communication model. Users and applications operate in terms of content, making it increasingly limiting and difficult to conform to IP's requirement to communicate by discovering and specifying location. To carry the Internet into the future, a conceptually simple yet transformational architectural shift is required, from today's focus on where ? addresses and hosts ? to what ? the content that users and applications care about.This project investigates a potential new Internet architecture called Named Data Networking (NDN). NDN capitalizes on strengths ? and addresses weaknesses ? of the Internet's current host-based, point-to-point communication architecture in order to naturally accommodate emerging patterns of communication. By naming data instead of their location, NDN transforms data into a first-class entity. The current Internet secures the data container. NDN secures the contents, a design choice that decouples trust in data from trust in hosts, enabling several radically scalable communication mechanisms such as automatic caching to optimize bandwidth. The project studies the technical challenges that must be addressed to validate NDN as a future Internet architecture: routing scalability, fast forwarding, trust models, network security, content protection and privacy, and fundamental communication theory. The project uses end-to-end testbed deployments, simulation, and theoretical analysis to evaluate the proposed architecture, and is developing specifications and prototype implementations of NDN protocols and applications.
