Abstract

   This document defines a collection of common data types and groupings
   in YANG data modeling language for layer 1 networks.  These derived
   common types and groupings are intended to be imported by modules
   that specifies the OTN networks, including the topology, tunnel,
   client signal adaptation and service.

1.  Introduction

   This document introduces a collection of common data types which
   would be used in Layer 1 networks.  The derived types and groupings
   are designed to be the common types applicable for modeling Traffic
   Engineering (TE) features for Layer 1 networks.

   Typical Layer 1 network, the Optical Transport Networking, was
   specified in [RFC7062].  Corresponding routing and signaling protocol
   have been specified in [RFC7138] and [RFC7139].  The types and
   groupings defined in this document is consistent to these document,
   and will be imported in other Layer 1 data models, including but not
   restrictive to, [I-D.ietf-ccamp-otn-topo-yang],
   [I-D.ietf-ccamp-otn-tunnel-model],
   [I-D.ietf-ccamp-client-signal-yang] and [I-D.ietf-ccamp-l1csm-yang].

   The data model in this draft has only types defined including
   groupings, typedef and identities.  There is no need to include
   configuration and state data according to the new Network Management
   Datastore Architecture [RFC8342].  The content in this draft is in
   consistent with other specifications, including [MEF63] for Layer 1
   service attributes, [ITU-Tg709] and [ITU-Tgsup43] for OTN data plane
