A YANG Data Model for Retrieval Methods for the Management of Operations, Administration, and Maintenance (OAM) Protocols That Use Connectionless Communications
コネクションレス型通信を使用する運用、管理、および保守（OAM）プロトコルの管理のための検索方法のYANGデータモデル
Abstract
概要
This document presents a retrieval method YANG data model for connectionless Operations, Administration, and Maintenance (OAM) protocols. It provides technology-independent RPC operations for OAM protocols that use connectionless communication. The retrieval methods model herein presented can be extended to include technology-specific details. There are two key benefits of this approach: First, it leads to uniformity between OAM protocols. Second, it supports both nested OAM workflows (i.e., performing OAM functions at different or the same levels through a unified interface) as well as interactive OAM workflows (i.e., performing OAM functions at the same levels through a unified interface).
このドキュメントでは、コネクションレス型の運用、管理、および保守（OAM）プロトコルの検索方法YANGデータモデルについて説明します。コネクションレス型通信を使用するOAMプロトコルに対して、テクノロジーに依存しないRPC操作を提供します。ここで紹介する検索方法モデルは、テクノロジー固有の詳細を含めるように拡張できます。このアプローチには2つの重要な利点があります。1つ目は、OAMプロトコル間の均一性につながります。第2に、ネストされたOAMワークフロー（つまり、統一されたインターフェースを介して異なるまたは同じレベルでOAM機能を実行する）とインタラクティブなOAMワークフロー（つまり、統一されたインターフェースを介して同じレベルでOAM機能を実行する）の両方をサポートします。

Operations, Administration, and Maintenance (OAM) are important networking functions that allow operators to:
運用、管理、および保守（OAM）は、オペレーターが次のことを行えるようにする重要なネットワーク機能です。
1. monitor network communications (i.e., reachability verification and Continuity Check)
1. ネットワーク通信を監視する（つまり、到達可能性の検証と継続性チェック）
2. troubleshoot failures (i.e., fault verification and localization)
2. 障害のトラブルシューティング（障害の検証とローカリゼーションなど）
3. monitor service-level agreements and performance (i.e., performance management)
3. サービスレベルアグリーメントとパフォーマンス（つまり、パフォーマンス管理）を監視する
An overview of OAM tools is presented in [RFC7276].
OAMツールの概要は[RFC7276]に示されています。
Ping and Traceroute [RFC4443], as well as Bidirectional Forwarding Detection (BFD) [RFC5880], are well-known fault verification and isolation tools, respectively, for IP networks [RFC792]. Over the years, different technologies have developed similar toolsets for equivalent purposes.
PingとTraceroute [RFC4443]、および双方向転送検出（BFD）[RFC5880]は、それぞれIPネットワーク[RFC792]のよく知られた障害検証および分離ツールです。長年にわたり、さまざまなテクノロジーが同等の目的で同様のツールセットを開発してきました。
This document presents an on-demand retrieval method YANG data model for OAM protocols that use connectionless communication. This model provides technology-independent RPC operations for OAM protocols that use connectionless communication (i.e., connectionless OAM). It is separated from the generic YANG data model for connectionless OAM [RFC8532] and can avoid mixing the models for the retrieved data from the retrieval procedures. It is expected that retrieval procedures will evolve faster than the data model [RFC8532] and will allow new procedures to be defined for retrieval of the same data defined by the generic YANG data model for connectionless OAM.
このドキュメントでは、コネクションレス型通信を使用するOAMプロトコルのオンデマンド検索方式のYANGデータモデルについて説明します。このモデルは、コネクションレス型通信（つまり、コネクションレス型OAM）を使用するOAMプロトコルにテクノロジーに依存しないRPCオペレーションを提供します。これはコネクションレス型OAM [RFC8532]の一般的なYANGデータモデルから分離されており、取得手順から取得したデータのモデルが混在することを回避できます。検索手順はデータモデル[RFC8532]よりも速く進化し、コネクションレス型OAMの汎用YANGデータモデルで定義された同じデータを検索するための新しい手順を定義できるようになることが期待されます。

This document describes an on-demand retrieval method YANG data model for OAM protocols that use connectionless communication. This model provides technology-independent retrieval procedures (RPC operations) for connectionless OAM protocols. It provides a flexible way to retrieve the data that is defined by the "ietf-connectionless-oam.yang" module [RFC8532].
このドキュメントでは、コネクションレス型通信を使用するOAMプロトコルのオンデマンド検索方式YANGデータモデルについて説明します。このモデルは、コネクションレス型OAMプロトコルにテクノロジーに依存しない検索手順（RPC操作）を提供します。 「ietf-connectionless-oam.yang」モジュール[RFC8532]で定義されたデータを取得する柔軟な方法を提供します。
The RPC model facilitates issuing commands to a Network Configuration Protocol (NETCONF) server (in this case to the device that needs to execute the OAM command) and obtaining a response.
RPCモデルは、ネットワーク構成プロトコル（NETCONF）サーバー（この場合はOAMコマンドを実行する必要があるデバイス）へのコマンドの発行と応答の取得を容易にします。
Under the "connectionless-oam-methods" module, we summarize common OAM functions and define two generic RPC operations: 'continuity-check' and 'path-discovery'. In practice, these RPC operations are activated on demand and are supported by corresponding technology-specific OAM tools [RFC7276]. For example, for the IP OAM model, the Continuity Check RPC corresponds to the IP Ping [RFC792] [RFC4443], while the path discovery RPC operation corresponds to IP Traceroute [RFC792] [RFC4443].
「connectionless-oam-methods」モジュールの下で、一般的なOAM機能を要約し、2つの一般的なRPC操作を定義します： 'continuity-check'と 'path-discovery'。実際には、これらのRPC操作はオンデマンドでアクティブ化され、対応するテクノロジー固有のOAMツール[RFC7276]によってサポートされます。たとえば、IP OAMモデルの場合、Continuity Check RPCはIP Ping [RFC792] [RFC4443]に対応し、パス検出RPC操作はIP Traceroute [RFC792] [RFC4443]に対応します。
Note that the RPC operation presented in this document is the base building block, which is used to derive a model for a technology-specific OAM (i.e., ICMP Ping [RFC792] [RFC4443] and Label Switched Path (LSP) Ping [RFC8029]). This base building block should be extended with corresponding technology-specific parameters. To facilitate this for future enhancements to data retrieval methods, the RPCs are captured under a separate module.
このドキュメントに記載されているRPC操作は、技術固有のOAM（つまり、ICMP Ping [RFC792] [RFC4443]およびラベルスイッチドパス（LSP）Ping [RFC8029]のモデルを導出するために使用される基本構成要素です。 ）。この基本構成要素は、対応するテクノロジー固有のパラメーターで拡張する必要があります。データ取得メソッドの将来の機能強化のためにこれを容易にするために、RPCは別のモジュールの下にキャプチャされます。
The generic 'tp-address' grouping is used as data input from different RPCs described in this document. The generic 'path-discovery-data' and 'continuity-check-data' groupings defined by the "ietf-connectionless-oam.yang" module [RFC8532] are used as data outputs from different RPCs described in this document. Similar methods, including other RPCs, can retrieve the data using the same data model (i.e., the "ietf-connectionless-oam.yang" module).
一般的な「tp-address」グループは、このドキュメントで説明されているさまざまなRPCからのデータ入力として使用されます。 「ietf-connectionless-oam.yang」モジュール[RFC8532]によって定義された一般的な「path-discovery-data」および「continuity-check-data」グループは、このドキュメントで説明されているさまざまなRPCからのデータ出力として使用されます。他のRPCを含む同様のメソッドは、同じデータモデル（「ietf-connectionless-oam.yang」モジュール）を使用してデータを取得できます。

The YANG module specified in this document defines a schema 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するように設計されたデータのスキーマを定義します。最下位のNETCONFレイヤーはセキュアなトランスポートレイヤーであり、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）です[RFC6242]。最下位のRESTCONFレイヤーはHTTPSであり、実装に必須のセキュアなトランスポートはTLS [RFC8446]です。
The Network Configuration Access Control Model (NACM) [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.
ネットワーク構成アクセス制御モデル（NACM）[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プロトコル操作およびコンテンツの事前構成されたサブセットに制限する手段を提供します。
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：
o continuity-check: Generates Continuity Check.
o 導通チェック：導通チェックを生成します。
o path-discovery: Generates path discovery.
o path-discovery：パスディスカバリを生成します。
These operations are used to retrieve the data from the device that needs to execute the OAM command. Unauthorized source access to some sensitive information in the above data may be used for network reconnaissance or lead to denial-of-service attacks on both the local device and the network.
これらの操作は、OAMコマンドを実行する必要があるデバイスからデータを取得するために使用されます。上記のデータの機密情報への不正なソースアクセスは、ネットワークの偵察に使用されたり、ローカルデバイスとネットワークの両方でサービス拒否攻撃につながる可能性があります。

The following is an example of extensions possible to the "ietf-connectionless-oam-methods" YANG data model defined in this document.
以下は、このドキュメントで定義されている「ietf-connectionless-oam-methods」YANGデータモデルに可能な拡張の例です。
The snippet below depicts an example of augmenting the "ietf-connectionless-oam-methods" YANG data model with ICMP ping attributes:
以下のスニペットは、「ietf-connectionless-oam-methods」YANGデータモデルをICMP ping属性で拡張する例を示しています。

"This minimum ping round-trip-time (RTT) received.";

leaf avg-rtt{

As discussed in the Introduction section of this document, the new retrieval procedures can be defined for retrieval of the same data defined by the base YANG data model for connectionless OAM protocols. This appendix demonstrates how the base connectionless OAM data model can be extended to support persistent data retrieval besides on-demand retrieval procedures defined in Section 3, i.e., first retrieve a persistent-id based on the destination test point location information, and then retrieve the export details based on persistent-id. Internet Protocol Flow Information Export (IPFIX) [RFC7011] or YANG-Push [YANG-Push] are currently outlined here as data export options. Additional export options can be added in the future.
このドキュメントの「はじめに」セクションで説明したように、新しい検索手順は、コネクションレス型OAMプロトコルの基本YANGデータモデルによって定義された同じデータを検索するために定義できます。この付録では、基本的なコネクションレスOAMデータモデルを拡張して、セクション3で定義したオンデマンド検索手順に加えて永続データ検索をサポートする方法を示します。つまり、最初に宛先テストポイントの場所情報に基づいて永続IDを取得し、次に永続IDに基づいて詳細をエクスポートします。インターネットプロトコルフロー情報エクスポート（IPFIX）[RFC7011]またはYANG-Push [YANG-Push]は現在、データエクスポートオプションとしてここで概説されています。追加のエクスポートオプションを将来追加することができます。
The YANG module "example-cl-oam-persistent-methods" shown below is intended as an illustration rather than a real definition of an RPC operation model for persistent data retrieval. For the sake of brevity, this module does not obey all the guidelines specified in [RFC8407].
以下に示すYANGモジュール「example-cl-oam-persistent-methods」は、永続的なデータ検索のためのRPCオペレーションモデルの実際の定義ではなく、説明を目的としています。簡潔にするために、このモジュールは[RFC8407]で指定されているすべてのガイドラインには従いません。
