      Management of Precision Network Slicing - Problem Statement
          draft-galis-precision-netslices-problem-statement-00

Abstract

   This document introduces Precision Network Slicing Management
   problems and their context. It represents an initial review of the
   Management of Network Slicing problem statement derived from the
   analysis of the technical gaps in IETF protocols ecosystem.  It
   complements and brings together the efforts being carried out in
   several other IETF working groups covering certain aspects of Network
   Slicing management functions and operations.

1  Introduction

   Network slicing (NS) is an approach to flexible isolation and
   allocation of network resources and network functions for a logical
   network instance, providing a high level of such network
   customization and quality service guarantee that includes also such
   customized reliability and security levels. NS transforms the
   networking perspective by abstracting, isolating, orchestrating,
   softwarizing, and separating logical network components from the
   underlying physical network supporting the introduction of new
   network architectures ([RFC1958], [RFC3439], [RFC3234]) and new
   service delivery [5G-ICN]. In general, a particular network slice
   consists of a union of subsets of (connectivity, storage, computing)
   resources & (Virtual) Network Functions & Service Functions [RFC7665]
