A YANG Data Model for WSON (Wavelength Switched Optical Networks)
draft-ietf-ccamp-wson-yang-26
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
(NMDA).

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
two encoding documents [RFC7581] and [RFC7579] that developed
protocol independent encodings based on [RFC7446].
[ITU-Tg6982] 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 [ITU-Tg6982].
What is not in scope of this document is both impairment-aware
optical networks and flexi-grid. Refer to
[I-D.ietf-ccamp-optical-impairment-topology-yang] for impairment-
aware optical network topology model and
[I-D.ietf-ccamp-flexigrid-yang] for flexi-grid optical network
topology model.
Additionally, transponders and resource blocks (e.g., 3R
Regeneration) models are not in the scope of this document.

Internet-Draft WSON Topology YANG Model September 2020
This document defines one YANG model: ietf-wson-topology (Section 3).
This document augments the generic TE topology draft
[I-D.ietf-teas-yang-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. Terminology and Notations
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:
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].
1.2. 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].

1.3. Prefix 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 the following table.
+-------------+-------------------------+------------------------+
| Prefix | YANG module | Reference |
+-------------+-------------------------+------------------------+
| l0-types | ietf-layer0-types |[ietf-ccamp-layer0-types]|
| wson | ietf-wson-topology | [RFCXXXX] |
| nw | ietf-network | [RFC8345] |
| nt | ietf-network-topology | [RFC8345] |
| tet | ietf-te-topology |[ietf-teas-yang-te-topo]|
+-------------+-------------------------+------------------------+
Note: The RFC Editor will replace XXXX with the number assigned to
the RFC once this draft becomes an RFC.

"This module provides a YANG data model for the routing and
wavelength assignment (RWA) Traffic Engineering (TE)
topology in wavelength switched optical networks (WSONs).
The YANG model described in this document is a WSON
technology-specific YANG model augmenting the generic TE
topology module (ietf-te-topology) based on the information
model developed in RFC 7446 and the two encoding documents
RFC 7579 and RFC 7581.

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 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 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 NETCONF access control model
[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.
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:
/nw:networks/nw:network/nw:network-types/tet:te-topology
/nw:networks/nw:network/nt:link/tet:te/tet:te-link-attributes

5. IANA Considerations
It is proposed to IANA to assign new URIs from the "IETF XML
Registry" [RFC3688] as follows:
URI: urn:ietf:params:xml:ns:yang:ietf-wson-topology
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
This document registers a YANG module in the YANG Module Names
registry [RFC7950] and [RFC6020].

namespace: urn:ietf:params:xml:ns:yang:ietf-wson-topology
