1. Introduction
Internet-based traffic is dramatically increasing every year.
Moreover, such traffic is also becoming more dynamic. Thus,
transport networks need to evolve from current DWDM systems towards
elastic optical networks, based on flexi-grid transmission and
switching technologies [RFC7698]. This technology aims at increasing
both transport network scalability and flexibility, allowing the
optimization of bandwidth usage.

Internet-Draft A YANG data model for Flexi-Grid October 2018
This document presents a YANG 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.

3. Flexi-grid network topology model overview
YANG is a data modeling language used to model configuration data
manipulated by the NETCONF protocol. Several YANG models have already
been specified for network configurations. For instance, the work in
[RFC8345] has proposed a generic YANG model for network/service
topologies and inventories. The work in
[I-D.draft-ietf-teas-yang-te-topo] presents a data model to
represent, retrieve and manipulate Traffic Engineering (TE)
Topologies. These models serve as base models that other technology
specific models can augment. A YANG model has also been proposed in
[I-D.draft-dharini-ccamp-dwdm-if-yang] to manage single channel
optical interface parameters of DWDM applications, and in
Lopez de Vergara, et al. Expires April 25, 2019 [Page 3]
Internet-Draft A YANG data model for Flexi-Grid October 2018
[I-D.draft-ietf-ccamp-wson-yang] another model has been specified for
the routing and wavelength assignment TE topology in wavelength
switched optical networks (WSONs). None of them are specific for
flexi-grid technology.
Then, as stated before, we propose a model to describe a flexi-grid
topology that is split in two YANG sub-modules:
o Flexi-grid-TED: In order to be compatible with existing
proposals, we augment the definitions contained in
[RFC8345] and [I-D.draft-ietf-teas-yang-te-topo], by defining
the different elements we can find in a flexi-grid network:
a node, a transponder and a link. For that, each of those elements
is defined as a container that includes a group of attributes.
References to the elements are provided to be later used in
the definition of a media channel. It also includes the data
types for the type of modulation, the flexi-grid technology,
the FEC, etc.
o Media-channel: This module defines the whole path from a source
transponder to the destination through a number of intermediate
nodes and links. For this, it takes the information defined before
in the flexi-grid TED. This module is described in
[I-D.draft-ietf-ccamp-flexigrid-media-channel-yang]
The following section provides a detailed view of the first module.
4. Main building blocks of the Flexi-grid TED
This section details the defined YANG module. It is listed below in
section 6.
The description of the three main components, flexi-grid-node,
flexi-grid-transponder and flexi-grid-link is provided below.

5. 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 1 |Flexi-grid| Link 2 |Flexi-grid| Link 3

'------------>| 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 TED 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.
Other information, such as the slot frequency and granularity are
also provided.
Lopez de Vergara, et al. Expires April 25, 2019 [Page 8]
Internet-Draft A YANG data model for Flexi-Grid October 2018
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.

7. Security Considerations
The transport protocol used for sending the managed information MUST
support authentication and SHOULD support encryption.
The defined data-model by itself does not create any security
implications.
8. IANA Considerations
The namespace used in the defined models is currently based on the
METRO-HAUL project URI. Future versions of this document could
register a URI in the IETF XML registry [RFC3688], as well as in the
YANG Module Names registry [RFC6020].
