Or is it on carrier level (each single carrier on a link, whatever the mode of the radio link?\r\n\r\nDue to the frequent change of throughput then also the Bandwidth utilization could change frequently.\r\nIt is mainly a performance counter (both as statistic/timely data value or on period-time basis data value).\r\n\r\nCould it be recovered from the node? It is not a standard counter, so not all devices are able to provide it.\r\nOr based on other data from the node (tx bytes sent) ?

+<p id="section-1-1">This document defines a YANG data model to describe topologies of microwave/millimeter wave (hereafter microwave is used to simplify the text).  The YANG data model describes radio links, supporting carrier(s) and the associated termination points. A carrier is a description of a link providing transport capacity over the air by a single carrier.  It is typically defined by its transmitting and receiving frequencies.  A radio link is a link providing the aggregated transport capacity of the supporting carriers in aggregated and/or protected configurations, which can be used to carry traffic on higher topology layers such as Ethernet and TDM.  The model augments "YANG Data Model for Traffic Engineering (TE) Topologies" defined in <span>[<a href="#RFC8795" class="cite xref">RFC8795</a>]</span>, which is based on "A YANG Data Model for Network Topologies" defined in <span>[<a href="#RFC8345" class="cite xref">RFC8345</a>]</span>.<a href="#section-1-1" class="pilcrow">¶</a></p>
+<p id="section-1-2">The microwave point-to-point radio technology provides connectivity on L0/L1 over a radio link between two termination points, using one or several supporting carriers in aggregated or protected configurations.  That application of microwave technology cannot be used to perform cross-connection or switching of the traffic to create network connectivity across multiple microwave radio links. Instead, a payload of traffic on higher topology layers, normally L2 Ethernet, is carried over the microwave radio link and when the microwave radio link is terminated at the endpoints, cross-connection and switching can be performed on that higher layer creating connectivity across multiple supporting microwave radio links.<a href="#section-1-2" class="pilcrow">¶</a></p>
+<p id="section-1-3">The microwave topology model is expected to be used between a Provisioning Network Controller (PNC) and a Multi Domain Service Coordinator(MDSC) <span>[<a href="#RFC8453" class="cite xref">RFC8453</a>]</span>.

+        </h3>
+<p id="section-3.4-1">Since microwave is a point-to-point radio technology providing connectivity on L0/L1 over a radio link between two termination points and cannot be used to perform cross-connection or switching of the traffic to create network connectivity across multiple microwave radio links, a majority of the leafs in the Data Model for Traffic Engineering (TE) Topologies augmented by the microwave topology model are not applicable.  An example of which leafs are considered applicable can be found in appendices <a href="#examples-mw-only" class="auto internal xref">Appendix A</a> and <a href="#examples-mw-imports" class="auto internal xref">Appendix B</a> in this document.<a href="#section-3.4-1" class="pilcrow">¶</a></p>
+<p id="section-3.4-2">More specifically, admin-status and oper-status are recommended to be reported for links only.  Status for termination points can be used when links are inter-domain and when the status of only one side of link is known, but since microwave is a point-to-point technology where both ends normally belong to the same domain it is not expected to be applicable in normal cases.  Furthermore, admin-status is not applicable for microwave radio links.  Enable and disable of a radio link is instead done in the constituent carriers.<a href="#section-3.4-2" class="pilcrow">¶</a></p>

When an L2 link is transported over a single supporting microwave radio link, the topologies could be as shown below.  Note that the figure just shows an example, there might be other possibilities to demonstrate such a topology.  The example of the instantiation encoded in JSON is using only a selected subset of the leafs from the L2 topology model <span>[<a href="#RFC8944" class="cite xref">RFC8944</a>]</span>.<a href="#appendix-B-4" class="pilcrow">¶</a></p>

+1.  Introduction
+
+   This document defines a YANG data model to describe topologies of
+   microwave/millimeter wave (hereafter microwave is used to simplify
+   the text).  The YANG data model describes radio links, supporting
+   carrier(s) and the associated termination points.  A carrier is a
+   description of a link providing transport capacity over the air by a
+   single carrier.  It is typically defined by its transmitting and
+   receiving frequencies.  A radio link is a link providing the
+   aggregated transport capacity of the supporting carriers in
+   aggregated and/or protected configurations, which can be used to
+   carry traffic on higher topology layers such as Ethernet and TDM.
+   The model augments "YANG Data Model for Traffic Engineering (TE)
+   Topologies" defined in [RFC8795], which is based on "A YANG Data
+   Model for Network Topologies" defined in [RFC8345].
+
+   The microwave point-to-point radio technology provides connectivity
+   on L0/L1 over a radio link between two termination points, using one
+   or several supporting carriers in aggregated or protected
+   configurations.  That application of microwave technology cannot be
+   used to perform cross-connection or switching of the traffic to
+   create network connectivity across multiple microwave radio links.
+   Instead, a payload of traffic on higher topology layers, normally L2
+   Ethernet, is carried over the microwave radio link and when the
+   microwave radio link is terminated at the endpoints, cross-connection
+   and switching can be performed on that higher layer creating
+   connectivity across multiple supporting microwave radio links.
+
+   The microwave topology model is expected to be used between a
+   Provisioning Network Controller (PNC) and a Multi Domain Service
+   Coordinator(MDSC) [RFC8453].  Examples of use cases that can be
+   supported are:
+
+   1.  Correlation between microwave radio links and the supported links
+       on higher topology layers. e.g. an L2 Ethernet topology.  This
+       information can be used to understand how changes in the
+       performance/status of a microwave radio link affect traffic on
+       higher layers.
+
+   2.  Propagation of relevant characteristics of a microwave radio
+       link, such as bandwidth, to higher topology layers, where it e.g.
+       could be used as a criterion when configuring and optimizing a
+       path for a connection/service through the network end to end.
+
+   3.  Optimization of the microwave radio link configurations on a
+       network level, e.g. with the purpose to minimize overall
+       interference and/or maximize the overall capacity provided by the
+       links.
+
+1.1.  Terminology and Definitions
+
+   The following acronyms are used in this document:
+
+   PNC Provisioning Network Controller
+
+   MDSC Multi Domain Service Coordinator
+
+1.2.  Tree Structure
+
+   A simplified graphical representation of the data model is used in
+   chapter 3.1 of this document.  The meaning of the symbols in these
+   diagrams is defined in [RFC8340].
+
+2.  Requirements Language
+
+   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
+   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
+   "OPTIONAL" in this document are to be interpreted as described in BCP
+   14 [RFC2119] [RFC8174] when, and only when, they appear in all
+   capitals, as shown here.

+3.2.  Relationship between radio links and carriers
+
+   A microwave radio link is always an aggregate of one or multiple
+   carries, in various configurations/modes.  The supporting carriers
+   are identified by its termination points and are listed in the
+   container bundled-links as part of the te-link-config in the YANG
+   Data Model for Traffic Engineering (TE) Topologies [RFC8795] for a
+   radio-link.  The exact configuration of the included carriers is
+   further specified in the rlt-mode container (1+0, 2+0, 1+1, etc.) for
+   the radio-link.  Appendix A includes JSON examples of how such a
+   relationship can be modelled.
+
+3.3.  Relationship with client topology model
+
+   A microwave radio link carries a payload of traffic on higher
+   topology layers, normally L2 Ethernet.  The leafs supporting-network,
+   supporting-node, supporting-link, and supporting-termination-point in
+   the generic YANG module for Network Topologies [RFC8345] are expected
+   to be used to model a relationship/dependency from higher topology
+   layers to a supporting microwave radio link topology layer.
+   Appendix A includes JSON examples of an L2 Ethernet link transported
+   over one supporting microwave link.
+
+3.4.  Applicability of the Data Model for Traffic Engineering (TE)
+      Topologies
+
+   Since microwave is a point-to-point radio technology providing
+   connectivity on L0/L1 over a radio link between two termination
+   points and cannot be used to perform cross-connection or switching of
+   the traffic to create network connectivity across multiple microwave
+   radio links, a majority of the leafs in the Data Model for Traffic
+   Engineering (TE) Topologies augmented by the microwave topology model
+   are not applicable.  An example of which leafs are considered
+   applicable can be found in appendices Appendix A and Appendix B in
+   this document.
+
+   More specifically, admin-status and oper-status are recommended to be
+   reported for links only.  Status for termination points can be used
+   when links are inter-domain and when the status of only one side of
+   link is known, but since microwave is a point-to-point technology
+   where both ends normally belong to the same domain it is not expected
+   to be applicable in normal cases.  Furthermore, admin-status is not
+   applicable for microwave radio links.  Enable and disable of a radio
+   link is instead done in the constituent carriers.

+4.  Security Considerations
+
+   The YANG module specified in this document defines schemas 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 or RESTCONF users to a
+   preconfigured subset of all available NETCONF or RESTCONF protocol
+   operations and content.
+
+   The YANG module specified in this document imports and augments the
+   ietf-network and ietf-network-topology models defined in [RFC8345].
+   The security considerations from [RFC8345] are applicable to the
+   module in this document.
+
+   There are a several 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.  These are the subtrees and data nodes
+   and their sensitivity/vulnerability:
+
+   *  rlt-mode: A malicious client could attempt to modify the mode in
+      which the radio link is configured and thereby change the intended
+      behaviour of the link.
+
+   *  tx-frequency, rx-frequency and channel-separation: A malicious
+      client could attempt to modify the frequency configuration of a
+      carrier which could modify the intended behaviour or make the
+      configurtion invalid and thereby stop the operation of it.
+
+5.  IANA Considerations
+
+   IANA is asked to assign a new URI from the "IETF XML Registry"
+   [RFC3688] as follows:
+
+   URI: urn:ietf:params:xml:ns:yang:ietf-microwave-topology
+   Registrant Contact: The IESG
+   XML: N/A; the requested URI is an XML namespace.
+
+   It is proposed that IANA should record YANG module names in the "YANG
+   Module Names" registry [RFC6020] as follows:
+
+       Name: ietf-microwave-topology
+       Maintained by IANA?: N
+       Namespace: urn:ietf:params:xml:ns:yang:ietf-microwave-topology

+Appendix A.  Microwave Topology Model with base topology models
+
+   This appendix provides some examples and illustrations of how the
+   Microwave Topology Model can be used.  The tree illustrates an
+   example of a complete Microwave Topology Model including the relevant
+   data nodes from network-topology and te-topology (base topology
+   models).  There are also JSON based instantiations of the Microwave
+   Topology Model for a couple of small network examples.
+
+   The tree below shows an example of the relevant leafs for a complete
+   Microwave Topology Model including the augmented Network Topology
+   Model defined in [RFC8345] and the Traffic Engineering (TE)
+   Topologies model defined in [RFC8795].

+Appendix B.  Microwave Topology Model with example extensions
+
+   This appendix provides an examples of how the Microwave Topology
+   Model can be used with the interface reference topology (ifref) and
+   the bandwidth-availability-topology (bwa) models.  There is also a
+   snippet of json to show geolocation information instance data.
+
+   The tree below shows an example of the relevant leafs for a complete
+   Microwave Topology Model including interface reference topology
+   (ifref) and bandwidth-availability-topology (bwa) models.

+   Microwave is a transport technology which can be used to transport
+   client services, such as L2 Ethernet links.  When an L2 link is
+   transported over a single supporting microwave radio link, the
+   topologies could be as shown below.  Note that the figure just shows
+   an example, there might be other possibilities to demonstrate such a
+   topology.  The example of the instantiation encoded in JSON is using
+   only a selected subset of the leafs from the L2 topology model
+   [RFC8944].
