    Internet Protocol Tunneling over Content Centric Mobile Networks
                        draft-irtf-icnrg-ipoc-01

Abstract

   This document describes a protocol that enables tunneling of Internet
   Protocol traffic over a Content Centric Network (CCNx) or a Named
   Data Network (NDN).  The target use case for such a protocol is to
   provide an IP mobility plane for mobile networks that might otherwise
   use IP-over-IP tunneling, such as the GPRS Tunneling Protocol (GTP)
   used by the Evolved Packet Core in LTE networks (LTE-EPC).  By
   leveraging the elegant, built-in support for mobility provided by
   CCNx or NDN, this protocol achieves performance on par with LTE-EPC,
   equivalent efficiency, and substantially lower implementation and
   protocol complexity [Shannigrahi].  Furthermore, the use of CCNx/NDN
   for this purpose paves the way for the deployment of ICN native
   applications on the mobile network.

1.  Introduction

   Content Centric Networking (such as CCNx or NDN, though CCNx is used
   for the rest of the document) provides some key advantages over IP
   networking that make it attractive as a replacement for IP for
   wireless networking.  In particular, by employing stateful
   forwarding, CCNx elegantly supports information retrieval by mobile
