                     Network Slice Provision Models
                 draft-homma-slice-provision-models-02

Abstract

   Network slicing is an approach to provide separate virtual network
   based on service requirements, and it's a key feature of the 5G.
   3GPP has standardized the specifications for network slicing in the
   5GS, but there are still some problems for realization of end-to-end
   network slices.  For complementing the lacks or expanding the
   usability, several organizations are proceeding standardization.
   However, the definitions and scopes of network slicing vary to some
   degree from one organization to another.  This document provides
   classification of provisioning models of network slice for clarifying
   the differences on the definitions and scopes.
