                     Network Slice Provision Models
                 draft-homma-slice-provision-models-01

Abstract

   Network slicing is an approach to provide separate virtual network
   based on service requirements.  It's a fundamental concept of the 5G,
   and the architecture and specification is under standardization in
   several organizations.  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.
