                    DetNet Configuration YANG Model
                     draft-geng-detnet-conf-yang-01

Abstract

   This document defines a YANG data Model for Deterministic Networking
   (DetNet), covering the device / link capabilities and resources.  It
   can be used in network capability advertising, device configuration
   and status reporting.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
