          Enabling ICN in 3GPP's 5G NextGen Core Architecture
                      draft-ravi-icnrg-5gc-icn-03

Abstract

   The proposed 3GPP's 5G core nextgen architecture (5GC) offers
   flexibility to introduce new user and control plane function,
   considering the support for network slicing functions, that allows
   greater flexibility to handle heterogeneous devices and applications.
   In this draft, we provide a short description of the proposed 5GC
   architecture, followed by extensions to 5GC's control and user plane
   to support Packet Data Unit (PDU) sessions from Information-Centric
   Networks (ICN).  The value of enabling ICN in 5GC is discussed using
   IP-based service scenarios in the context of 5G Local Area Networks
   (5GLAN).
