1. Introduction
Transport networks have evolved from traditional fixed-grid
Wavelength Switched Optical Networks (WSON) [RFC6163] to more
scalable and flexible elastic optical networks. These utilize flexi-
grid Dense Wavelength Division Multiplexing (DWDM) technologies
[RFC7698] to optimize bandwidth usage. Current DWDM Optical Network
deployments may include fixed-grid WSON, flexi-grid DWDM, or a
combination of both.
In the optical domain, a WDM tunnel typically originates and
concludes at a pair of transponders using one or more transceivers
dependent upon the data rate and encoding type of the transceivers.
These transponders are then connected to an intermediate line system
composed of optical switches and multiplexers, including
Reconfigurable Optical Add-Drop Multiplexers (ROADMs) and add-drop
multiplexers, complemented by optical amplifiers to boost the
transmission distance. The optical wavelength can be routed from the
transponder or an incoming fiber, through multiplexing, to various
outgoing fibers in the DWDM network. At optical nodes, wavelengths

Internet-Draft WDM Tunnel YANG Model October 2024
may undergo conversion via optical-electrical-optical (OEO)
regenerators, depending on the switching setup and fiber
configuration.
Optical services, transmitted via analog signals, require careful
provisioning across the network to maintain signal quality and
prevent interference between different wavelength channels. The
technology within optical nodes, like tunable transceivers or
Colorless, Directionless and Contentionless Flexi-grid (CDC-F)
ROADMs, introduces specific constraints that can limit WDM tunnel
path options. These constraints must be factored into WDM tunnel
provisioning and pre-computation. Additionally, assessing the end-
to-end optical performance metrics like Generalized Signal-to-noise
Ratio (G-SNR), Bit Error Rate (BER), and Q-factor is crucial to
ensure transmission quality and receiver signal integrity.
This draft introduces a YANG [RFC7950] data model for setting up and
managing TE tunnels and LSPs in DWDM Optical Networks. It aims to
provide an intent-based interface used by a control entity such as a
Software-defined Network (SDN) controller at its northbound to
establish services between endpoints, typically optical transponders.
Clients can utilize this model to either partially or fully delegate
service provisioning to the SDN controller, while still capable to
express additional constraints to guide its operation. Service
provisioning can be as simple as identifying the source and
destination transponders and delegate the rest of determination to
the SDN controller, or as explicit as specifying a complete detailed
path complete with tuned wavelengths and transceiver details.
This document identifies the WDM tunnel components, parameters and
their values, and characterizes the features and the performances of
the WDM elements. An application example is provided towards the end
of the document to understand their utility better.

3. Overview
The YANG data model in this draft builds upon the generic TE tunnel
model from [I-D.ietf-teas-yang-te]. This base model is suitable for
all TE-enabled networks and includes universal TE tunnel elements
like node addresses, tunnel termination points (TTPs), and path-level
constraints such as explicit path hops, label restrictions, and path
diversity. The current model enhances [I-D.ietf-teas-yang-te] by
incorporating WDM-specific attributes and constraints relevant to WDM
tunnels, including definitions for:
* Network-scope optical transceiver configuration constraints, e.g.,
operational modes, transceiver tuning constraints
* Network-scope WDM path routing policies for influencing WDM TE
path selection. For exmaple, whether or not using regenerator or
wavelength conversion is allowed, whether or not wavelength
retuing is allowed for tunable transceivers, etc.
* Network-scope optical performance constraints, e.g. the
generalized Signal-to-noise (G-SNR) margin and delta power of a
feasible optical path
* Path-scope WDM layer constraints and transceiver configurations
for working and protection path within a WDM tunnel
* List of WDM nodes, links, and optical wavelength that constitute
an end-to-end WDM path
* Other relevant optical attributes which characterize the optical
signal

The attributes described above are optional, allowing the model to
support both simplified and fully-explicit WDM tunnel provisioning to
meet diverse client requirements.
Additionally, the YANG model provides the status of a WDM tunnel,
which includes:
* Computed paths for various roles such as working, protection, and
restoration, indicating potential optical paths confirmed by the
SDN controller via pre-computation.
* Actual LSPs for each tunnel path, representing the optical paths
currently established in the network.
3.1. Integrated vs. External Optical Transponder
In optical networks built with traditional chassis-based DWDM optical
equipment, optical transponder (OTs) are typically inserted into the
chassis installed as cards. WDM tunnels are established between
pairs of OTs, with the SDN controller serving as the central entity
for provisioning and managing these tunnels.
In scenarios like data center interconnects (DCI), optical
transponders may be externally mounted on a 'pizza box' and linked
via dedicated fiber or wavelength multiplexer/demultiplexer to the
optical line system. These external OTs could be managed by the same
SDN controller or a different entity, such as an orchestrator.
Consequently, a WDM tunnel might be composed of several segments
joined to create a continuous end-to-end tunnel.
The YANG data model offers a cohesive interface for managing WDM
tunnels and tunnel segments, irrespective of transponder location.
4. Example of Use
To illustrate the model's application, consider an optical network
with various transponders, switches, and links. A depicted topology
outlines two WDM tunnel scenarios. In the first, an end-to-end WDM
tunnel (WDM Tunnel 1) comprises two physical paths (WDM Primary Path
1 and 2) linking two integrated optical transponders, Transponder A
and E, through WSON and Flexi-grid nodes. The second scenario
describes three WDM tunnel segments (WDM Tunnel Segment 2a to 2c)
connecting two external OTs, External OT node X and Y, via the same
nodes and links.

Figure 1: Topology Example
To configure an end-to-end WDM tunnel 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:
* 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 E identifiers, addresses and interfaces.
Guo, et al. Expires 21 April 2025 [Page 6]
Internet-Draft WDM Tunnel YANG Model October 2024
* 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.
* Then, we also define the links 1 to 5 that interconnect nodes,
indicating which WSON or flexi-grid labels are available.
* Other information, such as the slot frequency and granularity are
also provided.
After the nodes, links and transponders have been defined using
[I-D.ietf-ccamp-flexigrid-yang] and [RFC9094] we can configure the
tunnel from the information we have stored in the flexi-grid
topology, by querying which elements are available, and planning the
resources that have to be provided on each situation, taking into
account the global and path-specific WDM tunnel constraints. Note
that every element in the flexi-grid topology has a reference, and
this is the way in which they are called in the tunnel.
* Depending on the case, it is possible to define either the source
and destination node ports, or the source and destination node and
transponder. In our case, we would define a network tunnel, with
source transponder A and source node B, and destination
transponder E and destination node C. Thus, we are going to
follow path x.
* Then, for each link in the path x, we indicate which channel we
are going to use, providing information about the slots, and what
nodes are connected.
* Finally, the flexi-grid topology has to be updated with each
element usage status each time a tunnel is created or torn down.

description
"This grouping defines additional optional constraints for
transceiver configurations related to tunnel selection.
These constraints further limit the resources available
to the tunnel. All constraints operate inclusively, using
an AND logic. For example, if a specific frequency range
is selected, the tunnel must also be constrained to match
only that range.
When these constraints are combined with the operational
mode, the list of operational modes should exclude any
modes that cannot satisfy the additional constraints.
For instance, if the frequency is restricted to the C-band,
the list of operational modes should not include any modes
applicable only to the L-band.";

6. Security Considerations
The configuration, state, and action data defined in this document
are designed to be accessed via a management protocol with a secure
transport layer, such as NETCONF [RFC6241] or RESTCONF [RFC8040].
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.
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:

Editors note: we are using simplified description by folding similar
branches to avoid repetition.
7. IANA Considerations
This document requests IANA to register the following URIs in the
"ns" subregistry within the "IETF XML Registry" [RFC3688]. Following
the format in [RFC3688], the following registrations are requested.
URI: urn:ietf:params:xml:ns:yang:ietf-wdm-tunnel
Registrant Contact: The IESG
XML: N/A; the requested URI is an XML namespace.
This document requests IANA to register the following YANG modules in
the "IANA Module Names" [RFC6020]. Following the format in
[RFC6020], the following registrations are requested:
name: ietf-wdm-tunnel
namespace: urn:ietf:params:xml:ns:yang:ietf-wdm-tunnel
prefix: wdm-tnl
reference: RFC XXXX
RFC Editor: Please replace XXXX with the RFC number assigned to this
document.
