IETF Network Slice Use Cases and Attributes for Northbound Interface of
                     IETF Network Slice Controllers
                   draft-contreras-teas-slice-nbi-04

Abstract

   This document analyses the needs of potential customers of network
   slices realized with IETF techniques in several use cases, identifies
   the functionalities for the North Bound Interface (NBI) of an IETF
   Network Slice Controller to satisfy such requests.

1.  Introduction

   A number of new technologies, such as 5G, NFV and SDN are not only
   evolving the network from a pure technological perspective but also
   are changing the concept in which new services are offered to the
   customers [I-D.homma-slice-provision-models] by introducing the
   concept of network slicing.

   The transport network is an essential component in the end-to-end
   delivery of services and, consequently, it is necessary to understand
   what could be the way in which the transport network is consumed as a
