1. Terminology and Definitions
The following terms are used in this document:
Carrier Termination (CT) is an interface for the capacity provided
over the air by a single carrier. It is typically defined by its
transmitting and receiving frequencies.
Radio Link Terminal (RLT) is an interface providing packet capacity
and/or TDM capacity to the associated Ethernet and/or TDM interfaces
in a node and used for setting up a transport service over a
microwave/millimeter wave link.
The following acronyms are used in this document:
ACM Adaptive Coding Modulation
ATPC Automatic Transmit Power Control

CM Coding Modulation

2. Introduction
This document defines a YANG data model for management and control of
the radio link interface(s) and the relationship to packet (typically
Ethernet) and/or TDM interfaces in a microwave/millimeter wave node.
ETSI EN 302 217 series defines the characteristics and requirements
of microwave/millimeter wave equipment and antennas. Especially ETSI
EN 302 217-2 [EN 302 217-2] specifies the essential parameters for
the systems operating from 1.4GHz to 86GHz. The data model includes
configuration and state data.
The design of the data model follows the framework for management and
control of microwave and millimeter wave interface parameters defined
in [I-D.ietf-ccamp-microwave-framework]. This framework identifies
the need and the scope of the YANG data model, the use cases and
requirements that the model needs to support. Moreover, it provides
a detailed gap analysis to identify the missing parameters and
functionalities of the existing and established models to support the
specified use cases and requirements, and based on that recommends
how the gaps should be filled with the development of the new model.
According to the conclusion of the gap analysis, the structure of the
data model is based on the structure defined in
[I-D.ahlberg-ccamp-microwave-radio-link] and it augments RFC 7223 to
align with the same structure for management of the packet
interfaces. More specifically, the model will include interface
layering to manage the capacity provided by a radio link terminal for
the associated Ethernet and TDM interfaces, using the principles for
interface layering described in RFC 7223 as a basis.
The designed YANG data model uses established microwave equipment
and radio standards, such as ETSI EN 302 217-2, and the IETF: Radio
Link Model[I-D.ahlberg-ccamp-microwave-radio-link] and the ONF:
Microwave Modeling[ONF-model] as the basis for the definition of the
detailed leafs/parameters, and proposes new ones to cover identified
gaps which are analysed in[I-D.ietf-ccamp-microwave-framework].

3.2. Explanation of the Microwave Data Model
The leaves in the Interface Management Module augmented by Radio Link
Terminal (RLT) and Carrier Termination (CT) are not always relevant.
Ahlberg, et al. Expires January 4, 2018 [Page 5]
Internet-Draft Microwave YANG Model July 2017
"/interfaces/interface/enabled" is not relevant for RLT. Enable and
disable of an interface is done in the constituent CTs.
The packet related measurements "in-octets", "in-unicast-pkts", "in-
broadcast-pkts", "in-multicast-pkts", "in-discards", "in-errors",
"in-unknown-protos", "out-octets", "out-unicast-pkts", "out-
broadcast-pkts", "out-multicast-pkts", "out-discards", "out-errors"
are not within the scope of the microwave radio link domain and
therefore not relevant for RLT and CT.

5. Security Considerations
The YANG module defined in this memo is designed to be accessed via
the NETCONF protocol [RFC6241]. The 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 operations and content.
Ahlberg, et al. Expires January 4, 2018 [Page 33]
Internet-Draft Microwave YANG Model July 2017
There are a number of data nodes defined in the YANG module which 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., <editconfig>)
to these data nodes without proper protection can have a negative
effect on network operations.
The security considerations of [RFC7223] also apply to this document.
6. IANA Considerations
TBD.
