 Network Slicing - Introductory Document and Revised Problem Statement
                  draft-gdmb-netslices-intro-and-ps-02

Abstract

   This document introduces Network Slicing problems and the motivation
   for new work areas. It represents an initial revision of the Network
   Slicing problem statement derived from the analysis of the technical
   gaps in IETF protocols ecosystem.  It complements and brings together
   the silo efforts being carried out in several other IETF working groups
   to achieve certain aspects of Network Slicing functions and operations.

1.  Introduction

   Network Slicing (NS) refers to the managed partitions of physical
   and/or virtual network resources, network physical/virtual and
   service functions [RFC7665] that can act as an independent instance
   of a connectivity network and/or as a network cloud. Network resources
   include connectivity, compute, and storage resources.

   Network Slices considerably transform the networking perspective by
   abstracting, isolating, orchestrating, softwarizing, and separating
   logical network components from the underlying physical network
   resources and as such they enhance Internet architecture principles
   ([RFC1958], [RFC3439], [RFC3234]).

   The management plane creates the grouping of network resources (whereby
   network resources can be physical, virtual or a combination thereof),
   it connects with the physical and virtual  network and service functions
   ([SFC WG]) as appropriate, and it instantiates all of the network and
   service functions assigned to the slice. On the other hand, for slice
