YANG data model for Flexi-Grid Optical Networks
draft-ietf-ccamp-flexigrid-yang-06.txt
Abstract
This document defines a YANG module for managing flexi-grid optical
networks. The model defined in this document specifies a flexi-grid
traffic engineering database that is used to describe the topology of
a flexi-grid network. It is based on and augments existing YANG
models that describe network and traffic engineering topologies.
A partner document defines a second YANG module for flexi-grid media
channels, i.e., the paths from source to destination through a number
of intermediate nodes.

1. Introduction
The flexible grid (flexi-grid) optical network technology defined by
the International Telecommunication Union Telecommunication
Standardization Sector (ITU-T) and documented in Recommendation
G.694.1 [G.694.1] and G.872 [G.872] provides an enhanced Dense
Wavelength Division Multiplexing (DWDM) grid by defining a set of
nominal central frequencies, channel spacings, and the concept of the
"frequency slot". In such an environment, a data-plane connection is
switched based on allocated, variable-sized frequency ranges within

the optical spectrum, creating what is known as a flexible grid
(flexi-grid). This technology increases both transport network
scalability and flexibility, allowing the optimization of bandwidth
usage.
[RFC7698] provides a framework GMPLS-Based control of flexi-grid DWDM
networks while [RFC7699] defines generalized labels for the use in
flexi-grid in GMPLS networks.
This document presents a YANG [RFC7950] model for flexi-grid objects
in the dynamic optical network, including the nodes, transponders
and links between them, as well as how such links interconnect nodes
and transponders.
The YANG model for flexi-grid networks allows the representation of
the flexi-grid optical layer of a network, combined with the
underlying physical layer.
This document identifies the flexi-grid components, parameters and
their values, characterizes the features and the performances of the
flexi-grid elements. An application example is provided towards the
end of the document to better understand their utility.
A partner document defines a second YANG module that described flexi-
grid media channels, i.e., the paths from source to destination
through a number of intermediate nodes
[I-D.draft-ietf-ccamp-flexigrid-media-channel-yang].

3. Main building Blocks of the Flexi-grid Topology
This section describes the YANG module. It is specified in Section 5.
The description of the three main components, flexi-grid-node,
flexi-grid-transponder and flexi-grid-link is provided below.
flexi-grid-sliceable-transponders are also defined.
The syntax specification below uses the augmented Backus-Naur
Form (BNF) as described in [RFC5234].

4. Example of Use
In order to explain how this model is used, we provide the following
example. An optical network usually has multiple transponders,
switches (nodes) and links between them. Figure 1 shows a simple
topology, where two physical paths interconnect two optical
transponders.
Media channel

| Link 4 |Flexi-grid| Link 5 |
'------------>| node |<-----------'
| D |
+----------+
<-------------------------------------------------->
Path y
Figure 1. Topology example.
In order to configure a media channel to interconnect transponders A
and E, first of all we have to populate the flexi-grid topology YANG
model with all elements in the network:
1. We define the transponders A and E, including their FEC type, if
enabled, and modulation type. We also provide node identifiers
and addresses for the transponders, as well as interfaces
included in the transponders. Sliceable transponders can also be
defined if needed.
2. We do the same for the nodes B, C and D, providing their
identifiers, addresses and interfaces, as well as the internal
connectivity matrix between interfaces.
3. Then, we also define the links 1 to 5 that interconnect nodes and
transponders, indicating which flexi-grid labels are available.

Internet-Draft A YANG data model for Flexi-Grid July 2020
Other information, such as the slot frequency and granularity are
also provided.
Next, we can configure the media channel from the information we
have stored in the flexi-grid TED, by querying which elements are
available, and planning the resources that have to be provided on
each situation. Note that every element in the flexi-grid TED has a
reference, and this is the way in which they are called in the media
channel. We refer to
[I-D.draft-ietf-ccamp-flexigrid-media-channel-yang] to complete
this example.

6. 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 [RFC8341] 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:

7. IANA Considerations
IANA is requested to assigned a new URI from the "IETF XML Registry"
[RFC3688] as follows:
URI: urn:ietf:params:xml:ns:yang:ietf-flexi-grid-topology
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
IANA is requested to assign a new YANG module name in the "YANG
Module Names" registry [RFC6020] as follows:
Name: ietf-flexi-grid-topology
Namespace: urn:ietf:params:xml:ns:yang:ietf-flexi-grid-topology
Prefix: flexi-grid-topology
Reference: [This.I-D]
