Abstract
This document defines a YANG model for managing flexi-grid optical
media channels, complementing the information provided by the
flexi-grid topology model.
It is also grounded on other defined YANG abstract models.

1. Introduction
Transport networks are evolving from current DWDM systems towards
elastic optical networks, based on flexi-grid transmission and
switching technologies [RFC7698]. Such technology aims at increasing
both transport network scalability and flexibility, allowing the
optimization of bandwidth usage.

Internet-Draft YANG data model for Flexi-Grid media-channels Mar.2019
While [I-D.draft-ietf-ccamp-flexigrid-yang] focuses on flexi-grid
objects such as nodes, transponders and links, this document presents
a YANG [RFC7950] model for the flexi-grid media-channel. This YANG
module defines the whole path from a source transponder or node to
the destination through a number of intermediate nodes in the
flexi-grid network.
This document identifies the flexi-grid media-channel 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.
2. Conventions used in this document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
In this document, these words will appear with that interpretation
only when in ALL CAPS. Lower case uses of these words are not to be
interpreted as carrying RFC-2119 significance.
In this document, the characters ">>" preceding an indented line(s)
indicates a compliance requirement statement using the key words
listed above. This convention aids reviewers in quickly identifying
or finding the explicit compliance requirements of this RFC.
3. Flexi-grid media-channel overview
The present model defines a flexi-grid media-channel mainly
composed of:
- source address
- source flexi-grid port
- source flexi-grid transponder
- destination address
- destination flexi-grid port
- destination flexi-grid transponder
- A list of links that defines the path
- Other optical attributes
Each path can be a media-channel (only defined by source and
destination node) or a network media-channel (additionally needs
source and destination transponders). Therefore, all the attributes
are optional to support both situations.
Lopez de Vergara, et al. Expires September 25, 2019 [Page 3]
Internet-Draft YANG data model for Flexi-Grid media-channels Mar.2019
This is achieved by a combination of the traffic engineering tunnel
attributes explained in [I-D.draft-ietf-teas-yang-te] and augments
when necessary. For instance, source address, source flexi-grid
transponder, destination address and destination flexi-grid
transponder attributes are directly taken from tunnel, whereas other
attributes such as source flexi-grid port, destination flexi-grid
port are defined, as they are specific for flexi-grid.
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
<==================================================>
Path x
<-------------------------------------------------->
+----------+ +----------+
Link 1 |Flexi-grid| Link 2 |Flexi-grid| Link 3
.--->| node |<-------->| node |<---.
| | B | | C | |
| +----------+ +----------+ |
v v
/-----------\ /-----------\
/ Flexi-grid \ / Flexi-grid \
| transponder | | transponder |
\ A / \ E /
\-----------/ \-----------/
^ ^
| +----------+ |
| Link 4 |Flexi-grid| Link 5 |
'------------>| node |<-----------'
| D |
+----------+
<-------------------------------------------------->
Path y
Figure 1. Topology example.
After the nodes, links and transponders have been defined using
[I-D.draft-ietf-ccamp-flexigrid-yang], we can configure the
media-channel 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.
Note that every element in the flexi-grid topology has a reference,
and this is the way in which they are called in the media-channel.

Internet-Draft YANG data model for Flexi-Grid media-channels Mar.2019
1. 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 media
channel, with source transponder A and source node B, and
destination transponder E and destination node C. Thus, we are
going to follow path x.
2. 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.
3. Finally, the flexi-grid topology has to be updated with each
element usage status each time a media channel is created or torn
down.

Internet-Draft YANG data model for Flexi-Grid media-channels Mar.2019
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.
7. IANA Considerations
The namespace used in the defined model has to register a URI in
the IETF XML registry [RFC3688], as well as in the YANG Module
Names registry [RFC6020].
