              Network Slicing Management and Orchestration
                   draft-flinck-slicing-management-00

Abstract

   Network Slicing is worked in multiple SDOs from different view
   points.  As network slicing is an end-to-end topic, this draft
   proposes that network slices architecture [NS-Framework] aligns with
   the work done in NGMN, 3GPP and ETSI with relation to management and
   orchestration.  The key aspect that this draft makes is the rational
   for role and need for Network Slice Management Function (NSMF) entity
   that operates above Network Virtualization Function Orchestrator and
   PNFs Management Functions.  NSMF needs to support different
   abstractions of resources and to offer access to different management
   entities.

1.  Introduction

   The purpose of this draft is to highlight the essential aspects of
   network slice management from 3GPP, NGMN and ETSI relevant for the
   network slices architecture as described in [NS-Framework] and to
   propose a minimal alignment between these works to ensure
   compatibility between them.  NGMN documents
   "161010_NGMN_Network_Slicing_framework_v1.0.8" [NGMN_NS] and "5G
   Network and Service Management including Orchestration" [NGMN_NSMN]
   define Network Slicing and how it relates to overall Service and
   Network Management architecture.  The NGMN documents define as well
   the terminology adopted later by 3GPP and reflected in 3GPP
   [TR28.801].  In this paper, for sake of simplicity, only an
   "executive summary" of network slicing is given, while relying on
   both terminology and complete descriptions on the above mentioned
   documents.

   Network Slicing provides multiple logical networks on top of a
   partially shared network infrastructure as described in
   [NS-Framework].  Each instance of a network slice represents an
   independent end-to-end network that allows deployment of different
   architectural flavors in parallel slices.  These slices may be
   deployed and/or operated by the slice provider, or by the tenant who
