     Problem Statement of Supervised Heterogeneous Network Slicing
                  draft-geng-coms-problem-statement-01

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.
