Abstract

   This document describes the technical requirements and the related
   reference model for the intercommunication and coordination among
   devices in Autonomic Slicing Networking.  The goal is to define how
   the various elements in a network slicing context work and
   orchestrate together, to describe their interfaces and relations.
   While the document is written as generally as possible, the initial
   solutions are limited to the chartered scope of the WG.
