A YANG Data Model for Layer 1 Types
draft-ietf-ccamp-layer1-types-08
Abstract
This document defines a collection of common data types and groupings
in the YANG data modeling language for use with layer 1 networks.
These derived common types and groupings are intended to be imported
by modules that specify OTN networks, such as topology, tunnel,
client signal adaptation and service.

1. Introduction
This document specifies common data types for use in YANG [RFC7950]
data models of Layer 1 networks. The derived types and groupings are
types applicable to modeling Traffic Engineering (TE) for Layer 1
networks.
The Optical Transport Networking, a typical Layer 1 network, is
specified in [RFC7062]. The corresponding routing and signaling
protocol are specified in [RFC7138] and [RFC7139]. The types and
groupings defined in this document are consistent to those documents,
and can be imported into other Layer 1 data models, including but not
limited 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 only defines groupings, typedef and
identities. There is no configuration or state data as specified in
the Network Management Datastore Architecture [RFC8342]. The
document is consistent with other specifications, including [MEF63]
for Layer 1 service attributes, [ITU-Tg709] and [ITU-Tgsup43] for OTN
data plane definitions.
