A YANG model to manage the optical interface parameters for an external
transponder in a WDM network
draft-dharini-ccamp-dwdm-if-param-yang-00
Abstract
This memo defines a Yang model related to the Optical Transceiver
optical parameters characterising the 100G and above interfaces.
100G and above Transceivers support coherent transmission, different
modulation format, multiple FEC algorithms not yet specified by ITU-T
G.698.2 [ITU.G698.2] or any other ITU-T recommendation. The use
cases and the state of the Coherent transceivers is well describe in
draft-many-coherent-DWDM-if-control.
The Yang model defined in this memo can be used for Optical
Parameters monitoring and/or configuration of the endpoints of the
multi-vendor IaDI optical link.

Internet-Draft draft-dharini-ccamp-dwdm-if-param-yang-00 October 2016
1. Introduction
This memo defines a Yang model that translates and obsolete the SNMP
mib module defined in draft-galikunze-ccamp-dwdm-if-snmp-mib for
managing single channel optical interface parameters of DWDM
applications, using the approach specified in G.698.2. This model is
to support the optical parameters specified in ITU-T G.698.2
[ITU.G698.2], plus some parameters related to full coherent
transmission and not yet specified by ITU-T like modulation format,
finer Grid provisioning, multiple carrier, etc. The application
identifiers specified in ITU-T G.874.1 [ITU.G874.1] and the Optical
Power at Transmitter and Receiver side. Note that G.874.1
encompasses vendor-specific codes, which if used would make the
interface a single vendor IaDI and could still be managed.
[Editor's note: In G.698.2 this corresponds to the optical path from
point S to R; network media channel is also used and explained in
draft-ietf-ccamp-flexi-grid-fwk-02]
Management will be performed at the edges of the network media
channel (i.e., at the transmitters and receivers attached to the S
and R reference points respectively) for the relevant parameters
specified in G.698.2 [ITU.G698.2], G.798 [ITU.G798], G.874
[ITU.G874], and the performance parameters specified in G.7710/Y.1701
[ITU-T G.7710] and G.874.1 [ITU.G874.1].
G.698.2 [ITU.G698.2] is primarily intended for metro applications
that include optical amplifiers. Applications are defined in G.698.2
[ITU.G698.2] using optical interface parameters at the single-channel
connection points between optical transmitters and the optical
multiplexer, as well as between optical receivers and the optical
demultiplexer in the DWDM system. This Recommendation uses a
methodology which does not explicitly specify the details of the
optical network between reference point Ss and Rs, e.g., the passive
and active elements or details of the design. The Recommendation
currently includes unidirectional DWDM applications at 2.5 and 10
Gbit/s (with 100 GHz and 50 GHz channel frequency spacing). Work is
still under way for 40, 100 and Higher Gbit/s interfaces. There is
possibility for extensions to a lower channel frequency spacing.
This document specifically refers also to the "application code"
defined in the G.698.2 [ITU.G698.2] and included in the Application
Identifier defined in G.874.1 [ITU.G874.1] and G.872 [ITU.G872], plus
a few optical parameters not included in the G.698.2 application code
specification.
This draft refers and supports the draft-ietf-ccamp-dwdm-if-mng-ctrl-
fwk and draft-many-coherent-DWDM-if-control.

Internet-Draft draft-dharini-ccamp-dwdm-if-param-yang-00 October 2016
The building of a yang model describing and extending the optical
parameters defined in G.698.2 [ITU.G698.2], and reflected in G.874.1
[ITU.G874.1], allows the different vendors and operator to retrieve,
provision and exchange information across the G.698.2 multi-vendor
IaDI in a standardised way. In addition to the parameters specified
in ITU recommendations the Yang models support also the "vendor
specific application identifier", the Tx and Rx power at the Ss and
Rs points and the channel frequency and the detailed parameters
described in G.698.2 extending them to the new 100G and higher
coherent interfaces..
The Yang Model, reporting the Optical parameters and their values,
characterizes the features and the performances of the optical
components and allow a reliable link design in case of multi vendor
optical networks.
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
This memo specifies a Yang model for optical interfaces.
3. Conventions
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 RFC 2119 [RFC2119] In
the description of OIDs the convention: Set (S) Get (G) and Trap (T)
conventions will describe the action allowed by the parameter.

7. Security Considerations
The YANG module defined in this memo is designed to be accessed via
the NETCONF protocol [RFC6241]. he lowest NETCONF layer is the secure
transport layer and the mandatory-to-implement secure transport is
SSH [RFC6242]. The NETCONF access control model [RFC6536] provides
the means to restrict access for particular NETCONF users to a pre-
configured subset of all available NETCONF protocol operation and
content.
8. IANA Considerations
This document registers a URI in the IETF XML registry [RFC3688].
Following the format in [RFC3688], the following registration is
requested to be made:
URI: urn:ietf:params:xml:ns:yang:ietf-interfaces:ietf-ext-xponder-
wdm-if
Registrant Contact: The IESG.
XML: N/A, the requested URI is an XML namespace.
This document registers a YANG module in the YANG Module Names
registry [RFC6020].
This document registers a YANG module in the YANG Module Names
registry [RFC6020].
