      Deterministic Networking (DetNet) Controller Plane Framework
            draft-ietf-detnet-controller-plane-framework-00

Abstract

   This document provides a framework overview for the Deterministic
   Networking (DetNet) controller plane.  It discusses concepts and
   requirements that will be basis for Detnet controller plane solution
   documents.
