This document defines a YANG data model to describe microwave and millimeter-wave radio links in a network topology (hereafter, "microwave" is used to simplify the text). The YANG data model describes radio links, supporting carrier(s), and the associated carrier termination points [RFC8561]. A carrier is a single link providing transport capacity over the air. It is typically defined by its transmitting and receiving frequencies. A radio link provides the 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 Time-Division Multiplexing (TDM). The model augments the 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].
このドキュメントでは、ネットワークトポロジ内のマイクロ波とミリ波の無線リンクを説明するYangデータモデルを定義します（以下、「マイクロ波」はテキストを簡素化するために使用されます）。Yangデータモデルは、電波リンク、サポートキャリア、および関連するキャリアの終了ポイント[RFC8561]について説明しています。キャリアは、空気上の輸送容量を提供する単一のリンクです。通常、送信および受信周波数によって定義されます。無線リンクは、集計および/または保護された構成でのサポートキャリアの輸送能力を提供します。これを使用して、イーサネットや時間帯マルチプレックス（TDM）などのより高いトポロジ層のトラフィックを運ぶことができます。このモデルは、[RFC8345]で定義されたネットワークトポロジのYangデータモデルに基づく[RFC8795]で定義されているトラフィックエンジニアリング（TE）トポロジのYangデータモデルを増強します。
The microwave point-to-point radio technology provides connectivity on Layer 0 or Layer 1 (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 Layer 2 (L2) Ethernet, is carried over the microwave radio link. 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.
マイクロ波ポイントツーポイントラジオテクノロジーは、集約または保護された構成で1つまたは複数のサポートキャリアを使用して、2つの終端ポイント間のラジオリンクを介して、レイヤー0またはレイヤー1（L0/L1）の接続性を提供します。マイクロ波技術のアプリケーションを使用して、トラフィックのクロス接続または切り替えを実行して、複数のマイクロ波無線リンクにわたってネットワーク接続を作成することはできません。代わりに、より高いトポロジ層のトラフィックのペイロード、通常はレイヤー2（L2）イーサネットがマイクロ波無線リンクに掲載されます。エンドポイントでマイクロ波無線リンクが終了すると、複数のサポートマイクロ波無線リンクにわたって接続を作成する高レイヤーでの相互接続とスイッチングを実行できます。
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:
マイクロ波トポロジモデルは、プロビジョニングネットワークコントローラー（PNC）とマルチドメインサービスコーディネーター（MDSC）[RFC8453]の間で使用されると予想されます。サポートできるユースケースの例は次のとおりです。
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.
1. マイクロ波無線リンクと、より高いトポロジ層上のサポートされているリンクとの相関（L2イーサネットトポロジなど）。この情報は、マイクロ波無線リンクのパフォーマンス/ステータスの変化が、より高い層のトラフィックにどのように影響するかを理解するために使用できます。
2. Propagation of relevant characteristics of a microwave radio link, such as bandwidth, to higher topology layers, where it could be used as a criterion when configuring and optimizing a path for a connection or service through the network end to end.
2. 帯域幅などのマイクロ波無線リンクの関連する特性の伝播が高いトポロジ層への伝播。ネットワークエンドからエンドまでの接続またはサービスのパスを構成および最適化する際に基準として使用できます。
3. Optimization of the microwave radio link configurations on a network level, with the purpose to minimize overall interference and/or maximize the overall capacity provided by the links.
3. ネットワークレベルでのマイクロ波無線リンク構成の最適化。全体的な干渉を最小限に抑え、リンクが提供する全体的な容量を最大化する目的。

A microwave radio link is always an aggregate of one or multiple carriers in various configurations or modes. The supporting carriers are identified by their 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 modeled.
マイクロ波無線リンクは、常にさまざまな構成またはモードの1つまたは複数のキャリアの集合体です。サポートキャリアは終了ポイントによって識別され、トラフィックエンジニアリング（TE）トポロジー[RFC8795]のTE-Link-Configの一部として、無線リンクのTE-Link-Configの一部として、コンテナバンドルされたリンクにリストされています。付属のキャリアの正確な構成は、ラジオリンクのRLTモードコンテナ（1+0、2+0、1+1など）でさらに指定されています。付録Aには、そのような関係をどのようにモデル化できるかのJSON例が含まれています。
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 or 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.
マイクロ波無線リンクは、より高いトポロジ層、通常はL2イーサネット上のトラフィックのペイロードを搭載しています。ネットワークトポロジの一般的なYangモジュールのサポートネットワーク、サポートノード、サポートノード、サポートリンク、およびサポートポイント[RFC8345]は、より高いトポロジ層からサポートマイクロ波までの関係または依存関係をモデル化するために使用されると予想されます。無線リンクトポロジーレイヤー。付録Aには、1つのサポートマイクロ波リンクを介して輸送されたL2イーサネットリンクのJSON例が含まれています。
Since microwave is a point-to-point radio technology, a majority of the leafs in the Data Model for Traffic Engineering (TE) Topologies [RFC8795] augmented by the microwave topology model are not applicable. Examples of which leafs are considered applicable can be found in Appendices A and B in this document.
マイクロ波はポイントツーポイントラジオテクノロジーであるため、マイクロ波トポロジモデルによって増強されたトラフィックエンジニアリング（TE）トポロジーのデータモデル（TE）トポロジー[RFC8795]の葉の大部分は適用されません。このドキュメントの葉が適用可能であると見なされる例は、付録AとBにあります。
In the more specific context of the microwave-specific augmentations of te-topology, the admin-status, and oper-status leafs (from te-topology) are only applicable to microwave carriers (in the mw-link tree); they are not applicable to microwave radio links. Radio links are instead enabled or disabled in the constituent carriers. Furthermore, the status leafs related to mw-tp can be used with inter-domain links and when the status of only one side of the link is known. However, 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.
TE-Topologyのマイクロ波固有の増強のより特定のコンテキストでは、管理者ステータス、およびオペラステータス葉（TE-Topologyから）は、マイクロ波キャリア（MWリンクツリー）にのみ適用できます。それらは、マイクロ波無線リンクには適用されません。代わりに、ラジオリンクは、構成要素キャリアで有効または無効になっています。さらに、MW-TPに関連するステータスリーフは、ドメイン間リンクで使用でき、リンクの片側のみのステータスがわかっている場合に使用できます。ただし、マイクロ波は通常同じドメインに属するポイントツーポイントテクノロジーであるため、通常の場合には適用できるとは予想されていません。

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].
このドキュメントで指定されたYangモジュールは、NetConf [RFC6241]やRestConf [RFC8040]などのネットワーク管理プロトコルを介してアクセスするように設計されたデータのスキーマを定義しています。最低のネットコン層は安全な輸送層であり、実装から実装の安全な輸送は安全なシェル（SSH）[RFC6242]です。最も低いRESTCONF層はHTTPSであり、実装対象の安全な輸送はTLS [RFC8446]です。
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.
NetConf Access Controlモデル[RFC8341]は、特定のNetConfまたはRestConfユーザーのアクセスを、利用可能なすべてのNetConfまたはRestConfプロトコル操作とコンテンツの事前に構成されたサブセットに制限する手段を提供します。
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.
このドキュメントで指定されたYangモジュールは、[RFC8345]で定義されているIETFネットワークおよびIETFネットワークトポロジーモデルをインポートおよび増強します。[RFC8345]からのセキュリティ上の考慮事項は、このドキュメントのモジュールに適用できます。
There are a number of data nodes defined in this YANG module that are writable/creatable/deletable (i.e., config true, which is the default). These data nodes can 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:
このYangモジュールには、書き込み可能/クリエーション/削除可能な（つまり、デフォルトである構成真実）と定義されている多くのデータノードがあります。これらのデータノードは、一部のネットワーク環境で敏感または脆弱と見なすことができます。適切な保護なしにこれらのデータノードに操作を書き込む（例：編集config）は、ネットワーク操作に悪影響を与える可能性があります。これらは、サブツリーとデータノードとその感度/脆弱性です。
* rlt-mode: A malicious client could attempt to modify the mode in which the radio link is configured and, thereby, change the intended behavior of the link.
* RLT-Mode：悪意のあるクライアントは、無線リンクが構成されているモードを変更しようとする可能性があり、それにより、リンクの意図した動作を変更できます。
* tx-frequency and channel-separation: A malicious client could attempt to modify the frequency configuration of a carrier, which could modify the intended behavior or make the configuration invalid and, thereby, stop the operation of it.
* TX周波数とチャネル分離：悪意のあるクライアントは、キャリアの周波数構成を変更しようとする可能性があります。これにより、意図した動作を変更したり、構成を無効にしたり、その動作を停止したりできます。

This non-normative appendix provides examples of how the Microwave Topology Model can be used with the interface reference topology (ifref) [YANG-IF-REF-TOPO] and the bandwidth-availability-topology (bwa) [YANG-BWA-TOPO] models. There is also a snippet of JSON to show geolocation information instance data. When the JSON files have long lines, the long lines are wrapped as described in [RFC8792].
この非規範的な付録は、マイクロ波トポロジモデルをインターフェイス参照トポロジ（IFREF）[YANG-IF-REF-TOPO]および帯域幅と利用可能性と同時に使用する方法の例を提供します。モデル。また、地理的情報インスタンスデータを表示するJSONのスニペットもあります。JSONファイルに長い行がある場合、[RFC8792]に記載されているように長い線が包まれます。
The tree below shows an example of the relevant leafs for a complete Microwave Topology Model including interface reference topology (ifref) [YANG-IF-REF-TOPO] and bandwidth-availability-topology (bwa) [YANG-BWA-TOPO] models.
以下のツリーは、インターフェイス参照トポロジ（IFREF）[Yang-IF-Ref-Topo]および帯域幅-Width-Abailability-Topology（BWA）[Yang-BWA-Topo]モデルを含む完全なマイクロ波トポロジモデルの関連する葉の例を示しています。

Figure 4: Microwave Topology with Extensions Tree
図4：拡張ツリーを使用したマイクロ波トポロジ
Microwave is a transport technology that 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]. The example below uses Figure 3 and adds the interface-related information.
マイクロ波は、L2イーサネットリンクなどのクライアントサービスの輸送に使用できる輸送技術です。L2リンクが単一のサポートマイクロ波無線リンクに輸送される場合、トポロジは以下に示すようにできます。この図は、例を示しているだけであることに注意してください。そのようなトポロジを示す他の可能性があるかもしれません。JSONでエンコードされたインスタンス化の例は、L2トポロジモデル[RFC8944]から葉の選択されたサブセットのみを使用することです。以下の例では、図3を使用し、インターフェイス関連の情報を追加します。
