     Problem Statement of Supervised Heterogeneous Network Slicing
                  draft-geng-coms-problem-statement-00

Abstract

   This document discusses the general requirements and problem
   statement of supervised heterogeneous network slicing.  The purpose
   of this document is to identify the key network components that are
   used to create a network slice instance.  Base on this information, a
   general network slice template can be visualized.  Furthermore, the
   requirement of a common information model is identified and
   corresponding management consideration of heterogeneous network slice
   instance is also discussed.

1.  Introduction

   The concept of network slicing is not new but energized greatly under
   5G work in 3GPP.  It is expected that further 5G network should be
   capable of providing dedicated private network for different
   verticals according to their specific requirements, which are created
   by diversity of new services such as high definition (HD) video,
