Abstract

   This draft supplements the usecase described in
   [I-D.ietf-teas-ietf-network-slice-definition] from the perspective of
   the operator.In specific,it mainly includes two types of the network
   slice customers from the perspective of operators:

   o End-to-end slicing cloud-network collaboration

   o The branch departments that use slices within the operator.

1.  Introduction

   [I-D.ietf-teas-ietf-network-slice-definition] defines the concept of
   IETF network slices that provide connectivity coupled with a set of
   specific commitments of network resources between a number of
   endpoints over a shared network infrastructure and describes a number
   of use-cases benefiting from network slicing including:

   o 5G network slicing

   o Network wholesale services

   o Network sharing among operators

   o NFV connectivity and Data Center Interconnect

   In the document also clearly stated services that might benefit from
   the network slices include but not limited to the above use-cases.
