NDN for humans

In an attempt to lower the barriers to understanding this revolutionary (as well as evolutionary) way of looking at networking, three recently posted documents are likely to answer many of your questions (and inspire a few more):

(1) Almost 5 years ago, Van gave a 3+ hour tutorial on Content-Centric Networking for the Future Internet Summer School (FISS 09) hosted by the University of Bremen in Germany. We finally extracted an approximate transcript of this goldmine and are making it available, along with pointers to the slides and (4-part) video of his tutorial hosted by U. Bremen.

(Our FAQ answers the commonly asked question of How does NDN differ from Content-Centric Networking (CCN))

(2) A short (8-page) technical report, Named Data Networking, introducing the Named Data Networking architecture. (A version of this report will appear soon in ACM Computer Communications Review.)

(3) Another technical report exploring he potential social impacts of NDN: A World on NDN: Affordances & Implications of the Named Data Networking Future Internet Architecture. This paper highlights four departures from today’s TCP/IP architecture, which underscore the social impacts of NDN: the architecture’s emphases on enabling semantic classification, provenance, publication, and decentralized communication. These changes from TCP/IP could expand affordances for free speech, and produce positive outcomes for security, privacy and anonymity, but raise new challenges regarding data retention and forgetting. These changes might also alter current corporate and law enforcement content regulation mechanisms by changing the way data is identified, handled, and routed across the Web.

We welcome feedback on these and any NDN publications.

What is NDN?

The Named Data Networking (NDN) project aims to develop a new Internet architecture that can capitalize on strengths — and address weaknesses — of the Internet’s current host-based, point-to-point communication architecture in order to naturally accommodate emerging patterns of communication. 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. NDN Technical Report NDN-0001 Named Data Networking (NDN) Project is a slightly modified version of the NDN project proposal. The NDN project was funded by NSF in September 2010 as one of the four projects under NSF’s Future Internet Architecture Program.
