                     DetNet Flow Information Model
              draft-ietf-detnet-flow-information-model-01

Abstract

   This document describes flow and service information model for
   Deterministic Networking (DetNet).  The DetNet service is provided
   either for a Layer 3 or a Layer 2 flow.  This document provides
   DetNet flow and service information model both for Layer 3 and Layer
   2 flows in an integrated fashion.
