      Deterministic Networking (DetNet) Controller Plane Framework
            draft-malis-detnet-controller-plane-framework-04

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.
