1.  Introduction

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

   The concept of Network Slicing (NS) is considered a key mechanism for
   5G networks to serve vertical industries with widely different
   service needs, in term of latency, reliability, capacity, and domain
   specific extra functionalities.  It does so by exposing isolated
   partitions of network resources and services.  The IETF Bar-BoF
   NETSLICES activity studies the need for supporting protocols.  In
   particular, [I-D.gdmb-netslices-intro-and-ps] defines Network Slicing
   in a broad context and suggests related problems and work areas.  It
   also identifies the need to provide use cases such as, for example,
   ultra-low latency and massive-connectivity machine communication
   services.  We propose to review ongoing NS work in 3GPP within the
   present document.  This constitutes in our view another valid type of
   use case, since 3GPP architecture may ultimately use or integrate
   with NS solutions defined in IETF.

   Sections 2 to 6 aim to represent the current state of network slicing
   and related aspects in 3GPP.  We attempted to leave our own analysis
   out of these sections and present it into section 7.  For simplicity,
   3GPP-specific acronyms are defined in the section they are used,
   which is mostly section 3.
