    Internet Protocol Tunneling over Content Centric Mobile Networks
                        draft-irtf-icnrg-ipoc-00

Abstract

   This document describes a protocol that enables tunneling of Internet
   Protocol traffic over a Content Centric Network (CCN) 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 CCN 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 CCN/NDN for this
   purpose paves the way for the deployment of ICN native applications
   on the mobile network.

1.  Introduction

   Content Centric Networking 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, CCN elegantly supports information retrieval by mobile
   client devices without the need for tunneling or a location
   registration protocol.  Furthermore, CCN supports a client device
   utilizing multiple network attachments (e.g. multiple radio links)
