                    Network Slicing - 3GPP Use Case
             draft-defoy-netslices-3gpp-network-slicing-02

Abstract

   This document describes work conducted at the 3GPP standard
   organization on 5G Network Slicing.  Its goal is to provide detailed
   use cases, and help better define requirements, for Internet
   Protocols supporting Network Slicing.
