A YANG model to manage the optical interface parameters for an external
transponder in a WDM network
draft-dharini-ccamp-dwdm-if-yang-00
Abstract
This memo defines a Yang model that translates the SNMP mib module
defined in draft-galikunze-ccamp-dwdm-if-snmp-mib for managing single
channel optical interface parameters of DWDM applications. This
model is to support the optical parameters specified in ITU-T G.698.2
[ITU.G698.2] and application identifiers specified in ITU-T G.874.1
[ITU.G874.1] . 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.
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-yang-00 March 2016
1. Introduction
This memo defines a Yang model that translates 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], 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 and 100 Gbit/s interfaces. There is
possibility for extensions to a lower channel frequency spacing.
This document specifically refers 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-kdkgall-ccamp-dwdm-if-mng-
ctrl-fwk
The building of a yang model describing 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,
G.Galimberti, et al. Expires September 18, 2016 [Page 3]
Internet-Draft draft-dharini-ccamp-dwdm-if-yang-00 March 2016
provision and exchange information across the G.698.2 multi-vendor
IaDI in a standardized way. In addition to the parameters specified
in ITU recommendations the Yang models support also the "vendor
specifica application identifier", the Tx and Rx power at the Ss and
Rs points and the channel frequency.
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.
Although RFC 3591 [RFC3591], which draft-galikunze-ccamp-DWDM-if-
snmp-mib is extending, describes and defines the SNMP MIB of a number
of key optical parameters, alarms and Performance Monitoring, as this
RFC is over a decade old, it is primarily pre-OTN, and a more
complete and up-to-date description of optical parameters and
processes can be found in the relevant ITU-T Recommendations. The
same considerations can be applied to the RFC 4054 [RFC4054].
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.

Figure 1 shows a set of reference points, for single-channel
connection between transmitters (Tx) and receivers (Rx). Here the
DWDM network elements include an OM and an OD (which are used as a
pair with the opposing element), one or more optical amplifiers and
may also include one or more OADMs.

4.1. Optical Parameters Description
The link between the external transponders through a WDM network
media channels are managed at the edges, i.e. at the transmitters
(Tx) and receivers (Rx) attached to the S and R reference points
respectively. The set of parameters that could be managed are
defined by the "application code" notation
The definitions of the optical parameters are provided below to
increase the readability of the document, where the definition is

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-
