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.

尽管互联网远远超出了预期，但它也扩大了初始假设，通常会造成挑战其基本沟通模型的争吵。用户和应用程序在内容方面运行，使其越来越有限，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，从今天的关注点开始，需要一个简单而又简单的变革型建筑转变？地址和主机？到什么？用户和应用程序关心的内容。本项目调查了一个名为命名数据网络（NDN）的潜在新互联网体系结构。 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体系结构，以自然地适应新兴的通信模式。通过命名数据而不是其位置，NDN将数据转换为一流的实体。当前的互联网可保护数据容器。 NDN确保了内容，这是一种设计选择，它使对主机信任的数据信任取消了信任，从而实现了几种可扩展的通信机制，例如自动缓存，以优化带宽。 该项目研究必须应对NDN作为未来的互联网体系结构的技术挑战：路由可扩展性，快速转发，信任模型，网络安全性，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台部署，仿真和理论分析来评估所提出的体系结构，并正在开发NDN协议和应用程序的规范和原型实现。
