A YANG Data Model for WSON (Wavelength Switched Optical Networks)
draft-ietf-ccamp-wson-yang-18
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
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].

Internet-Draft WSON YANG Model December 2018
This document augments the generic TE topology draft [TE-TOPO].
What is not in scope of this document is both impairment-aware WSON
and flex-grid.
This document defines two YANG models: ietf-wson-topology (Section
3) and ietf-layer0-types (Section 4).
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:
o client
o server
o augment
o data model
o data node
The following terms are defined in [RFC6241] and are not redefined
here:
Lee, et al. Expires May 2018 [Page 3]
Internet-Draft WSON YANG Model December 2018
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 | [RFCXXXX] |
| 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.
YANG module "ietf-layer0-types" (defined in Section 4) references
[RFC6163], [RFC7205], and [RFC7698].

description
"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 [TE-TOPO] based on the information model
developed in [RFC7446] and the two encoding documents
[RFC7581] and [RFC7579] that developed protocol independent
encodings based on [RFC7446].

5. 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 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:
