Abstract
This document defines a YANG model for managing flexi-grid optical
media channels, complementing the information provided by the
flexi-grid TED 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 Oct.2018
While [I-D.draft-ietf-ccamp-flexigrid-yang] focuses on flexi-grid
objects such as nodes, transponders and links, this document presents
a YANG 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 April 25, 2019 [Page 3]
Internet-Draft YANG data model for Flexi-Grid media-channels Oct.2018
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
/-----------\ /-----------\

| transponder | | transponder |

^ ^
| +----------+ |
| 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 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.
Lopez de Vergara, et al. Expires April 25, 2019 [Page 4]
Internet-Draft YANG data model for Flexi-Grid media-channels Oct.2018
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 TED has to be updated with each element
usage status each time a media channel is created or torn down.

6. 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.
7. 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].
