FIA: Collaborative Research: Named Data Networking (NDN)

虽然互联网的发展远远超出了人们的预期，但它也扩展了最初的假设，经常引发挑战其基本通信模式的争斗。用户和应用程序根据内容进行操作，这使得它越来越受到限制，并且难以符合IP通过发现和指定位置进行通信的要求。为了将互联网带入未来，需要一个概念上简单但具有变革性的架构转变，从今天的重点放在哪里？地址和主机？什么用户和应用程序关心的内容。这个项目研究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利用优势？并解决弱点？互联网当前基于主机的点对点通信架构的一个重要组成部分，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。当前的互联网保护数据容器。NDN保护内容，这是一种将数据信任与主机信任相结合的设计选择，支持几种根本可扩展的通信机制，例如自动缓存以优化带宽。 该项目研究了验证NDN作为未来互联网架构必须解决的技术挑战：路由可扩展性，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。该项目使用端到端测试平台部署，仿真和理论分析来评估所提出的架构，并正在开发NDN协议和应用程序的规范和原型实现。

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.
