Abstract

   This document describes the current research outcomes in Network
   Coding (NC) for Content-Centric Networking (CCNx) / Named Data
   Networking (NDN), and clarifies the technical considerations and
   potential challenges for applying NC in CCNx/NDN.  This document is
   the product of the Coding for Efficient Network Communications
   Research Group (NWCRG) and the Information-Centric Networking
   Research Group (ICNRG).

1.  Introduction

   Information-Centric Networking (ICN) in general, and Content-Centric
   Networking (CCNx) [16] or Named Data Networking (NDN) [18] in
   particular, have emerged as a novel communication paradigm advocating
   the retrieval of data based on their names.  This paradigm pushes
   content awareness into the network layer.  It is expected to enable
   consumers to obtain the content they desire in a straightforward and
   efficient manner from the heterogenous networks they may be connected
   to.  The CCNx/NDN architecture has introduced innovative ideas and
