          Native Deployment of ICN in LTE, 4G Mobile Networks
                    draft-suthar-icnrg-icn-lte-4g-01

Abstract

   Mobile networks using LTE, 4G technologies are complex. Managing
   mobility and content delivery using IP transport is challenging and
   not optimized for content delivery. IP unicast routing from server to
   clients is used for delivery of multimedia content to User Equipment
   (UE), where each user gets separate stream. From bandwidth and
   routing perspective this approach is inefficient. Multicast and
   broadcast technologies have emerged recently for mobile networks, but
   their deployments are very limited or at an experimental stage due to
   complex architecture and radio spectrum issues. ICN is a rapidly
   emerging technology with built in features for efficient multimedia
   content delivery, however majority of the work is focused either on
   fixed networks or unlicensed WiFi-based wireless networks. The main
   focus of this document is on native deployment of ICN in cellular
   mobile networks by embedding ICN into 3GPP protocol stack at IP
   datagram or replacing IP for non-IP datagrams. ICN has an inherent
   capability for anchorless mobility, security and it is optimized for
   content delivery using local caching at the edge. We believe that ICN
   native or dual stack (with IP) deployment will bring all inherent
   benefits and help in optimizing mobile networks.
