Abstract

   This document describes the hybrid information-centric networking
   (hICN) architecture for IPv6.  The specifications describe a way to
   implement information-networking functionalities into IPv6.  The
   objective is to use IPv6 without creating overlays with a new packet
   format as an additional encapsulation.  The intent of the present
   design is to introduce some IPv6 routers in the network with
   additional packet processing operations to implement ICN functions.
   Moreover, the current design is tightly integrated into IPv6 to allow
   easy interconnection to IPv6 networks with the additional design
   objective to exploit existing IPv6 protocols as much as possible as
   they are, or extend them where needed.

1.  Introduction

   The objective of this document is to describe hybrid ICN, a network
   protocol that integrates ICN in IPv6, at a minimum cost in terms of
   required modifications in end-points and routers and in a way to
   guarantee transparent interconnection with IP without using overlays.
   Extensions for IPv4 exist but are out of scope for this document.

   The ICN reference design used in this document is CCNx as described
