1.  Introduction

   Information-Centric Networks in general, and Content-Centric
   Networking (CCN) [15] or Named Data Networking (NDN) [16] in
   particular, have emerged as a novel communication paradigm advocating
   to retrieve data through 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
   CCN/NDN architecture has introduced innovative ideas and has
   stimulated research in a variety of areas, such as in-network
   caching, name-based routing, multi-path transport, content security,
   and so on.  One key benefit of requesting content by name is that it
