     Information-Centric Networking (ICN): CCN and NDN Terminology
                    draft-irtf-icnrg-terminology-00

Abstract

   Information Centric Networking (ICN) is a new paradigm where network
   communications are accomplished by requesting named content, instead
   of sending packets to destination addresses.  Named Data Networking
   (NDN) and Content-Centric Networking (CCN) are two prominent ICN
   architectures.  This document provides an overview of the terminology
   and definitions that have been used in describing concepts in these
   two projects.  While there are other ICN architectures, they are not
   part of the NDN and CCN vision and as such are out of scope for this
   document.

1.  Introduction

   Information-centric networking (ICN) is an approach to evolve the
   Internet infrastructure from the existing host-centric design to a
   data-centric architecture, where accessing data by name becomes the
   essential network primitive.  The goal is to let applications refer
   to data independently of their location or means of transportation,
