                      Network Slicing Architecture
                  draft-geng-netslices-architecture-02

Abstract

   This document defines the overall architecture of network slicing.
   Based on the general architecture, basic concepts of network slicing
   and examples of network slicing instances are introduced for
   clarification purposes.  Some architectural considerations about the
   data plane, control plane, management and orchestration of network
   slicing are described to give a general view of network slicing
   implementation principles.
