A YANG Data Model for WSON (Wavelength Switched Optical Networks)
draft-ietf-ccamp-wson-yang-22
Abstract
This document provides a YANG data model for the routing and
wavelength assignment (RWA) TE topology in wavelength switched
optical networks (WSONs). The YANG data model defined in this
document conforms to the Network Management Datastore Architecture
defined in RFC 8342.

1. Introduction
This document provides a YANG data model for the routing and
wavelength assignment (RWA) Traffic Engineering (TE) topology in
transparent wavelength switched optical networks (WSONs). The YANG
model described in this document is a WSON technology-specific YANG
model based on the information model developed in [RFC7446] and the

Internet-Draft WSON YANG Model July 2019
two encoding documents [RFC7581] and [RFC7579] that developed
protocol independent encodings based on [RFC7446].
[G.698.2] defines amplified multichannel dense wavelength division
multiplexing applications with single channel optical interfaces.
The YANG data model defined in this document refers to the standard
application mode defined in [G.698.2].
What is not in scope of this document is both impairment-aware
optical networks and flexi-grid. Refer to [Impairment] for
impairement-aware optical network topology model and [flexi-grid]
for flexi-grid optical network topology model.
Additionally, resource block models (e.g., 3R Regeneration) is not
also in the scope of this document, which will be addressed in a
separate document.
This document defines one YANG model: ietf-wson-topology (Section
3). This document augments the generic TE topology draft [TE-TOPO].
There are multiple applications for the yang data model defined in
this document. For example, nodes within the network can use the
data model to capture their understanding of the overall WSON
topology and expose it to a controller. A controller can further
propagate the topology to other controllers. The YANG model is used
by NETCONF [RFC6020], [RFC8341] or a RESTCONF [RFC8040] protocol.
The YANG data model defined in this document conforms to the Network
Management Datastore Architecture [RFC8342].
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
1.2. Terminology
Refer to [RFC7446] and [RFC7581] for the key terms used in this
document.
The following terms are defined in [RFC7950] and are not redefined
here:
Lee, et al. Expires January 2020 [Page 3]
Internet-Draft WSON YANG Model July 2019
o client
o server
o augment
o data model
o data node
The following terms are defined in [RFC6241] and are not redefined
here:
o configuration data
o state data
The terminology for describing YANG data models is found in
[RFC7950].
1.3. Tree diagram
A simplified graphical representation of the data model is used in
chapter 2 of this this document. The meaning of the symbols in
these diagrams is defined in [RFC8340].
1.4. Prefixes in Data Node Names
In this document, names of data nodes and other data model objects
are prefixed using the standard prefix associated with the
corresponding YANG imported modules, as shown in Table 1.
+-------------+-------------------------+-----------------+
| Prefix | YANG module | Reference |
+-------------+-------------------------+-----------------+
| layer0-type | ietf-layer0-types | [Layer0-Types] |
| wson | ietf-wson-topology | [RFCXXXX] |
| nw | ietf-network | [RFC8345] |
| nt | ietf-network-topology | [RFC8345] |
| tet | ietf-te-topology | [TE-TOPO] |
+-------------+-------------------------+-----------------+
Table 1: Prefixes and corresponding YANG modules
Note: The RFC Editor will replace XXXX with the number assigned to
the RFC once this draft becomes an RFC.

4. Security Considerations
The YANG module specified in this document defines a schema for data
that is designed to be accessed via network management protocols
such as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF
Lee, et al. Expires January 2020 [Page 67]
Internet-Draft WSON YANG Model July 2019
layer is the secure transport layer, and the mandatory-to-implement
secure transport is Secure Shell (SSH) [RFC6242]. The lowest
RESTCONF layer is HTTPS, and the mandatory-to-implement secure
transport is TLS [RFC8446].
The NETCONF access control model [RFC6536] provides the means to
restrict access for particular NETCONF users to a preconfigured
subset of all available NETCONF protocol operations and content. The
NETCONF Protocol over Secure Shell (SSH) [RFC6242] describes a
method for invoking and running NETCONF within a Secure Shell (SSH)
session as an SSH subsystem. The Network Configuration Access
Control Model (NACM) [RFC8341] provides the means to restrict access
for particular NETCONF or RESTCONF users to a preconfigured subset
of all available NETCONF or RESTCONF protocol operations and
content.
A number of configuration data nodes defined in this document are
writable/deletable (i.e., "config true"). These data nodes may be
considered sensitive or vulnerable in some network environments.
There are a number of data nodes defined in this YANG module that
are writable/creatable/deletable (i.e., config true, which is the
default). These data nodes may be considered sensitive or
vulnerable in some network environments. Write operations (e.g.,
edit-config) to these data nodes without proper protection can have
a negative effect on network operations. These are the subtrees and
data nodes and their sensitivity/vulnerability:
