The LMAP framework has three basic elements: Measurement Agents (MAs), Controllers, and Collectors. Measurement Agents initiate the actual measurements, which are called Measurement Tasks in the LMAP terminology. The Controller instructs one or more MAs and communicates the set of Measurement Tasks an MA should perform and when. The Collector accepts Reports from the MAs with the Results from their Measurement Tasks.
LMAPフレームワークには、測定エージェント（MA）、コントローラー、およびコレクターの3つの基本要素があります。測定エージェントは、LMAP用語で測定タスクと呼ばれる実際の測定を開始します。コントローラーは1つ以上のMAに指示し、MAが実行する必要がある測定タスクのセットとタイミングを通知します。コレクターは、MAからのレポートとその測定タスクの結果を受け入れます。
The YANG data model for LMAP has been split into three modules:
LMAPのYANGデータモデルは、3つのモジュールに分割されています。
1. The module ietf-lmap-common.yang provides common definitions such as LMAP-specific data types.
1. モジュールietf-lmap-common.yangは、LMAP固有のデータ型などの一般的な定義を提供します。
2. The module ietf-lmap-control.yang defines the data structures exchanged between a Controller and Measurement Agents.
2. モジュールietf-lmap-control.yangは、コントローラーと測定エージェントの間で交換されるデータ構造を定義します。
3. The module ietf-lmap-report.yang defines the data structures exchanged between Measurement Agents and Collectors.
3. モジュールietf-lmap-report.yangは、測定エージェントとコレクターの間で交換されるデータ構造を定義します。
As shown in Figure 1, a Controller, implementing ietf-lmap-common.yang and ietf-lmap-control.yang as a client, will instruct Measurement Agents, which implement ietf-lmap-common.yang and ietf-lmap-control.yang as servers. A Measurement Agent, implementing ietf-lmap-common.yang and ietf-lmap-report.yang, will send results to a Collector, which implements ietf-lmap-common.yang and ietf-lmap-report.yang as a server.
図1に示すように、クライアントとしてietf-lmap-common.yangおよびietf-lmap-control.yangを実装するコントローラーは、ietf-lmap-common.yangおよびietf-lmap-controlを実装する測定エージェントに指示します。サーバーとしてのヤン。 ietf-lmap-common.yangとietf-lmap-report.yangを実装する測定エージェントは、ietf-lmap-common.yangとietf-lmap-report.yangをサーバーとして実装するコレクターに結果を送信します。

The LMAP Information Model [RFC8193] is divided into six aspects. They are mapped into the YANG data model as explained below:
LMAP情報モデル[RFC8193]は、6つの側面に分かれています。以下で説明するように、これらはYANGデータモデルにマップされます。
o Preconfiguration Information: This is not modeled explicitly since bootstrapping information is outside the scope of this data model. Implementations may use some of the Configuration Information also for bootstrapping purposes.
o 事前構成情報：ブートストラップ情報はこのデータモデルの範囲外であるため、これは明示的にモデル化されていません。実装では、ブートストラップの目的でも一部の構成情報を使用できます。
o Configuration Information: This is modeled in the /lmap/agent subtree, the /lmap/schedules subtree, and the /lmap/tasks subtree described below. Some items have been left out because they are expected to be dealt with by the underlying protocol.
o 構成情報：これは、以下で説明する/ lmap / agentサブツリー、/ lmap / schedulesサブツリー、および/ lmap / tasksサブツリーでモデル化されています。いくつかの項目は、基本的なプロトコルで処理されることが予想されるため、省略されています。
o Instruction Information: This is modeled in the /lmap/suppressions subtree, the /lmap/schedules subtree, and the /lmap/tasks subtree described below.
o 指示情報：これは、以下で説明する/ lmap / suppressionsサブツリー、/ lmap / schedulesサブツリー、および/ lmap / tasksサブツリーでモデル化されています。
o Logging Information: Some of the Logging Information, in particular 'success/failure/warning messages in response to information updates from the Controller', will be handled by the protocol used to manipulate the LMAP-specific configuration. The LMAP data model defined in this document assumes that runtime Logging Information will be communicated using protocols that do not require a formal data model, e.g., the syslog protocol defined in [RFC5424].
o ログ情報：一部のログ情報、特に「コントローラーからの情報更新に応じた成功/失敗/警告メッセージ」は、LMAP固有の構成を操作するために使用されるプロトコルによって処理されます。このドキュメントで定義されているLMAPデータモデルは、ランタイムログ情報が、正式なデータモデルを必要としないプロトコル、たとえば[RFC5424]で定義されているsyslogプロトコルを使用して通信されることを前提としています。
o Capability and Status Information: Some of the Capability and Status Information is modeled in the /lmap/capability subtree. The list of supported Tasks is modeled in the /lmap/capabilities/ task list. Status Information about Schedules and Actions is included in the /lmap/schedules subtree. Information about network interfaces can be obtained from the ietf-interfaces YANG data model [RFC7223]. Information about the hardware and the firmware can be obtained from the ietf-system YANG data model [RFC7317]. A device identifier can be obtained from the ietf-hardware YANG data model [YANG-HARDWARE].
o 機能とステータス情報：一部の機能とステータス情報は、/ lmap / capabilityサブツリーでモデル化されています。サポートされているタスクのリストは、/ lmap / capabilities /タスクリストでモデル化されています。スケジュールとアクションに関するステータス情報は、/ lmap / schedulesサブツリーに含まれています。ネットワークインターフェイスに関する情報は、ietf-interfaces YANGデータモデル[RFC7223]から取得できます。ハードウェアとファームウェアに関する情報は、ietf-system YANGデータモデル[RFC7317]から取得できます。デバイス識別子は、ietf-hardware YANGデータモデル[YANG-HARDWARE]から取得できます。
o Reporting Information: This is modeled by the report data model to be implemented by the Collector. Measurement Agents send results to the Collector by invoking an RPC on the Collector.
o レポート情報：これは、コレクターによって実装されるレポートデータモデルによってモデル化されます。測定エージェントは、コレクターでRPCを呼び出すことにより、結果をコレクターに送信します。
These six Information Model aspects use a collection of common information objects. These common information objects are represented in the YANG data model as follows:
これらの6つの情報モデルの側面は、共通の情報オブジェクトのコレクションを使用します。これらの共通情報オブジェクトは、YANGデータモデルで次のように表されます。
o Schedules: Schedules are modeled in the /lmap/schedules subtree.
o スケジュール：スケジュールは/ lmap / schedulesサブツリーでモデル化されます。
o Channels: Channels are not modeled since the NETCONF server configuration data model [NETCONF-CLIENT-SERVER] already provides a mechanism to configure NETCONF server Channels.
o チャネル：NETCONFサーバー構成データモデル[NETCONF-CLIENT-SERVER]はすでにNETCONFサーバーチャネルを構成するメカニズムを提供しているため、チャネルはモデル化されていません。
o Task Configurations: Configured Tasks are modeled in the /lmap/ tasks subtree.
o タスク構成：構成されたタスクは、/ lmap / tasksサブツリーでモデル化されます。
o Event Information: Event definitions are modeled in the /lmap/ events subtree.
o イベント情報：イベント定義は、/ lmap /イベントサブツリーでモデル化されます。

The YANG module defined in this document 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 Transport Layer Security (TLS) [RFC5246].
このドキュメントで定義されている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できるように設計されています。最下層のNETCONF層はセキュアなトランスポート層であり、実装に必須のセキュアなトランスポートはセキュアシェル（SSH）[RFC6242]です。最下位のRESTCONF層はHTTPSであり、実装に必須のセキュアなトランスポートはトランスポート層セキュリティ（TLS）[RFC5246]です。
The NETCONF access control model [RFC6536] 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アクセス制御モデル[RFC6536]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プロトコル操作およびコンテンツの事前構成済みサブセットに制限する手段を提供します。
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 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:
このYANGモジュールには、書き込み可能/作成可能/削除可能なデータノードが多数定義されています（つまり、config true、デフォルトです）。これらのデータノードは、一部のネットワーク環境では機密または脆弱であると見なされる場合があります。適切な保護なしにこれらのデータノードに書き込み操作（edit-configなど）を行うと、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、およびそれらの機密性/脆弱性です。
/lmap/agent This subtree configures general properties of the Measurement Agent such as its identity, measurement point, or Controller timeout. This subtree should only have write access for the system responsible for configuring the Measurement Agent.
/ lmap / agentこのサブツリーは、ID、測定ポイント、コントローラのタイムアウトなど、測定エージェントの一般的なプロパティを設定します。このサブツリーには、測定エージェントの構成を担当するシステムへの書き込みアクセス権のみが必要です。
/lmap/tasks This subtree configures the Tasks that can be invoked by a Controller. This subtree should only have write access for the system responsible for configuring the Measurement Agent. Care must be taken to not expose Tasks to a Controller that can cause damage to the system or the network.
/ lmap / tasksこのサブツリーは、コントローラーによって呼び出すことができるタスクを構成します。このサブツリーには、測定エージェントの構成を担当するシステムへの書き込みアクセス権のみが必要です。システムまたはネットワークに損傷を与える可能性のあるタスクをコントローラーに公開しないように注意する必要があります。
/lmap/schedules This subtree is used by a Controller to define the Schedules and Actions that are executed when certain events occur. Unauthorized access can cause unwanted load on the device or network, or it might direct measurement traffic to targets that become victims of an attack.
/ lmap / schedulesこのサブツリーは、特定のイベントが発生したときに実行されるスケジュールとアクションを定義するためにコントローラーによって使用されます。不正アクセスは、デバイスまたはネットワークに不要な負荷をかける可能性があります。または、攻撃の犠牲になるターゲットに測定トラフィックを転送する可能性があります。
/lmap/suppressions This subtree is used by a Controller to define Suppressions that can temporarily disable the execution of Schedules or Actions. Unauthorized access can either disable measurements that should normally take place or cause measurements to take place during times when normally no measurements should take place.
/ lmap / suppressionsこのサブツリーは、スケジュールまたはアクションの実行を一時的に無効にできる抑制を定義するためにコントローラーによって使用されます。不正アクセスは、通常行われるはずの測定を無効にするか、通常は行われないはずの時間に測定を行わせる可能性があります。
/lmap/events This subtree is used by a Controller to define events that trigger the execution of Schedules and Actions. Unauthorized access can either disable measurements that should normally take place or cause measurements to take place during times when normally no measurements should take place or at a frequency that is higher than normally expected.
/ lmap / eventsこのサブツリーは、コントローラーがスケジュールとアクションの実行をトリガーするイベントを定義するために使用されます。不正アクセスにより、通常は行われるはずの測定が無効になるか、通常は測定が行われないはずの時間に、または通常予想されるよりも高い頻度で測定が行われる可能性があります。
Some of the readable data nodes in this YANG module may be considered sensitive or vulnerable in some network environments. It is thus important to control read access (e.g., via get, get-config, or notification) to these data nodes. These are the subtrees and data nodes and their sensitivity/vulnerability:
このYANGモジュールの一部の読み取り可能なデータノードは、一部のネットワーク環境では機密または脆弱であると見なされる場合があります。したがって、これらのデータノードへの読み取りアクセスを制御することが重要です（たとえば、get、get-config、または通知を介して）。これらは、サブツリーとデータノード、およびそれらの機密性/脆弱性です。
/lmap/agent This subtree provides information about the Measurement Agent. This information may be used to select specific targets for attacks.
/ lmap / agentこのサブツリーは、測定エージェントに関する情報を提供します。この情報は、攻撃の特定のターゲットを選択するために使用される可能性があります。
/lmap/capabilities This subtree provides information about the capabilities of the Measurement Agent, including its software version number and the Tasks that it supports. This information may be used to execute targeted attacks against specific implementations.
/ lmap / capabilitiesこのサブツリーは、ソフトウェアのバージョン番号やサポートされるタスクなど、測定エージェントの機能に関する情報を提供します。この情報は、特定の実装に対して標的型攻撃を実行するために使用される可能性があります。
/lmap/schedules This subtree provides information about the Schedules and their associated Actions executed on the Measurement Agent. This information may be used to check whether attacks against the implementation are effective.
/ lmap / schedulesこのサブツリーは、測定エージェントで実行されるスケジュールとそれに関連するアクションに関する情報を提供します。この情報は、実装に対する攻撃が有効かどうかを確認するために使用できます。
/lmap/suppressions This subtree provides information about the Suppressions that can be active on the Measurement Agent. This information may be used to predict time periods where measurements take place (or do not take place).
/ lmap / suppressionsこのサブツリーは、測定エージェントでアクティブにできる抑制に関する情報を提供します。この情報は、測定が行われる（または行われない）期間を予測するために使用できます。
Some of the RPC operations in this YANG module may be considered sensitive or vulnerable in some network environments. It is thus important to control access to these operations. These are the operations and their sensitivity/vulnerability:
このYANGモジュールの一部のRPC操作は、一部のネットワーク環境では機密または脆弱であると見なされる場合があります。したがって、これらの操作へのアクセスを制御することが重要です。これらは操作とその感度/脆弱性です：
/report The report operation is used to send locally collected measurement results to a remote Collector. Unauthorized access may leak measurement results, including those from passive measurements.
/report The report operation is used to send locally collected measurement results to a remote Collector. Unauthorized access may leak measurement results, including those from passive measurements.
The data model uses a number of identifiers that are set by the Controller. Implementors may find these identifiers useful for the identification of resources, e.g., to identify objects in a file system providing temporary storage. Since the identifiers used by the YANG data model may allow characters that may be given special interpretation in a specific context, implementations must ensure that identifiers are properly mapped into safe identifiers.

Since the identifiers used by the YANG data model may allow characters that may be given special interpretation in a specific context, implementations must ensure that identifiers are properly mapped into safe identifiers.
The data model allows specifying options in the form of name/value pairs that are passed to programs. Implementors ought to take care that option names and values are passed literally to programs. In particular, shell expansions that may alter option names and values must not be performed.
データモデルでは、プログラムに渡される名前と値のペアの形式でオプションを指定できます。実装者は、オプションの名前と値が文字通りプログラムに渡されるように注意する必要があります。特に、オプション名と値を変更する可能性のあるシェル展開は実行しないでください。

Sometimes Tasks may require complicated parameters that cannot easily be fit into options, i.e., a list of name/value pairs. In such a situation, it is possible to augment the ietf-lmap-control.yang and ietf-lmap-report.yang data models with definitions for more complex parameters. The following example module demonstrates this idea using the parameters of UDP latency metrics as an example (although UDP latency metric parameters do not really need such an extension module).
タスクには、オプションに簡単に適合できない複雑なパラメーター、つまり名前と値のペアのリストが必要になる場合があります。このような状況では、ietf-lmap-control.yangおよびietf-lmap-report.yangデータモデルに、より複雑なパラメーターの定義を追加することができます。次のサンプルモジュールは、UDPレイテンシメトリックのパラメータを例として使用してこのアイデアを示しています（ただし、UDPレイテンシメトリックパラメータは、このような拡張モジュールを実際には必要としません）。
