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, slot widths, and the concept of the
"frequency slot". This technology increases both transport network

Internet-Draft Flexi-Grid YANG July 2021
scalability and flexibility, allowing the optimization of bandwidth
usage.
[RFC7698] provides a framework for GMPLS-Based control of flexi-grid
DWDM networks while [RFC7699] defines generalized labels for the use
of GMPLS in flexi-grid networks.
This document presents a YANG data model [RFC7950] for flexi-grid
objects in the dynamic optical network, including nodes, transponders
and links, as well as how such links interconnect nodes.
This document identifies the flexi-grid components, parameters and
their values, characterizes the features and the performances of the
flexi-grid elements. For this, it augments [RFC8795], and imports
the generic Layer 0 types and use of "media-channel" defined in
[I-D.ietf-ccamp-layer0-types].
An application example in Section 4 is also provided to better
understand the utility of this YANG model.
A partner document defines a second YANG module that described flexi-
grid tunnels, i.e., the paths from source to destination through a
number of intermediate nodes
[I-D.ietf-ccamp-flexigrid-media-channel-yang].
Impairment-aware traffic engineering topology is described in
[I-D.ietf-ccamp-optical-impairment-topology-yang].
The YANG data model defined in this document conforms to the Network
Management Datastore Architecture (NMDA) [RFC8342].
2. Terminology
Refer to [RFC7698] and [RFC7699] 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
Lopez de Vergara, et al.Expires January 13, 2022 [Page 3]
Internet-Draft Flexi-Grid YANG July 2021
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].
3. Tree Diagram
A simplified graphical representation of the data model is used in
this document. The meaning of the symbols in these diagrams is
defined in [RFC8340].
3.1. 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 Figure 1. It uses
prefixes from [I-D.ietf-ccamp-layer0-types], [RFC8345], and
[RFC8795].
+-------------+-------------------------+-----------------+
| Prefix | YANG module | Reference |

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. Figure 1 shows a simple topology.

Figure 2: Topology Example
In order to configure a network 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:
o We define the transponders within nodes A and E as tunnel
termination points (TTPs) and provide their internal local link
connectivity towards the node interfaces. We also provide nodes A
and B identifiers, addresses and interfaces.
o 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.
o Then, we also define the links 1 to 5 that interconnect nodes,
indicating which flexi-grid labels are available.
o Other information, such as the slot frequency and granularity are
also provided.
5. YANG Data Model for Flexi-Grid Topology
5.1. Flexi-Grid Topology Data Model Overview
This document aims to describe the data model for Flexi-Grid
topology. As a classic Traffic-engineering (TE) technology, Flexi-
Grid provide WDM switching in transport network. Therefore the YANG
Lopez de Vergara, et al.Expires January 13, 2022 [Page 5]

module presented in this document augments from a more generic
Traffic Engineered (TE) network topology data model, i.e., the ietf-
te-topology, as specified in [RFC8795], following the guidelines
provided in section 6 of [RFC8795].
Common types, identities and groupings defined in
[I-D.ietf-ccamp-layer0-types] are reused in this document.
The figure below shows the augmentation relationship between YANG
models.

Figure 3: Relationship between Flexi-Grid and TE topology models
The entities and TE attributes, such as node, termination points and
links, are still applicable for describing an Flexi-Grid topology and
the model presented in this document only specifies with technology-
specific attributes/information.
The Flexi-Grid specific attributes in [RFC7699], including the grid
type, channel spacing, slot width granularity, n and m parameters,
can be used to represent the label information. These attributes
have been specified in [I-D.ietf-ccamp-layer0-types], and used in
this document for augmentation of the generic TE topology model.
The YANG module ietf-flexi-grid-topology defined in this document
conforms to the Network Management Datastore Architecture (NMDA)
defined in [RFC8342].
5.2. Attributes Augmentation
There are a few characteristics augmenting to the generic TE
topology.
Lopez de Vergara, et al.Expires January 13, 2022 [Page 6]
Internet-Draft Flexi-Grid YANG July 2021
Following the guidelines in [RFC8795], a flexi-grid-topology network-
type is specified as the indicator of Flexi-Grid in the topology as
follows.
augment /nw:networks/nw:network/nw:network-types/tet:te-topology:
+--rw flexi-grid-topology!
Figure 4: Flexi-Grid Topology Augmentation
A flexi-grid-node presence container is specified, augmenting the
generic TE node attributes, to indicate that the TE node is a Flexi-
Grid node
augment /nw:networks/nw:network/nw:node/tet:te
/tet:te-node-attributes:
+--rw flexi-grid-node!
Figure 5: Flex-Grid Node Augmentation
It is assumed that all the Flexi-Grid nodes are reconfigurable.
5.3. Bandwidth Augmentation
As described in Section 4.2 of [RFC7699], there is some overlap
between bandwidth and label in layer0.
The flexi-grid label resource information described in section 5.4,
is sufficient to describe also the spectrum resources within a flexi-
grid network. Therefore, the model does not define any augmentation
for the te-bandwidth containers defined in [RFC8795].
5.4. Label Augmentation
The model augments all the occurrences of the label-restriction list
with flexi-grid technology specific attributes using the flexi-grid-
label-range-info grouping defined in [I-D.ietf-ccamp-layer0-types].
The Flexi-Grid label resource information described in section 5.4,
is sufficient to describe also the spectrum resources within a flexi-
Grid network. Therefore, the YANG model does not define any

augmentation for the te-bandwidth containers defined in
[I-D.ietf-ccamp-layer0-types].
Moreover, following the guidelines in [RFC8795], the model augments
all the occurrences of the te-label container with the flexi-Grid
technology specific attributes using the flexi-grid-label-start-end,
flexi-grid-label-hop and flexi-grid-label-step groupings defined in
[I-D.ietf-ccamp-layer0-types].

8. 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
Transport Layer Security (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 SSH [RFC6242] describes a method for invoking and
running NETCONF within a 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:

9. 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:
