The document specifies a common attachment circuits (ACs) YANG data model, which is designed to be reusable by other models. This design is meant to ensure consistent AC structures among models that manipulate ACs. For example, this common model can be reused by service models to expose ACs as a service, service models that require binding a service to a set of ACs, network and device models to provision ACs, etc.
このドキュメントは、他のモデルが再利用できるように設計された共通のアタッチメントサーキット（ACS）Yangデータモデルを指定します。この設計は、ACを操作するモデル間で一貫したAC構造を確保することを目的としています。たとえば、この共通モデルをサービスモデルで再利用して、ACSをサービスとして公開することができます。これは、ACS、ネットワーク、デバイスモデルのセットにサービスをバインドする必要があるサービスモデルを必要とします。

Connectivity services are provided by networks to customers via dedicated terminating points (e.g., Service Functions (SFs), Customer Premises Equipment (CPE), Autonomous System Border Routers (ASBRs), data center gateways, or Internet Exchange Points (IXPs)). A connectivity service ensures data transfer from (or destined to) a given terminating point to (or originating from) other terminating points. Objectives for such a connectivity service may be negotiated and agreed upon between a customer and a network provider.
接続サービスは、専用の終端ポイント（サービス関数（SFS）、顧客施設機器（CPE）、自律システムボーダールーター（ASBR）、データセンターゲートウェイ、またはインターネット交換ポイント（IXPS））を介して顧客にネットワークによって提供されます。接続サービスは、特定の終端ポイントから他の終端ポイントから（または発信する）ポイントからデータ転送を保証します。このような接続サービスの目的は、顧客とネットワークプロバイダーの間で交渉され、合意される場合があります。
For that data transfer to take place within the provider network, it is assumed that adequate setup is provisioned over the links connecting the customer's terminating points to the provider network (typically, a Provider Edge (PE)), thereby enabling successful data exchange. This necessary provisioning is referred to in this document as an "attachment circuit" (AC), while the underlying link is referred to as the "bearer".
プロバイダーネットワーク内でそのデータ転送が行われると、顧客の終了ポイントをプロバイダーネットワーク（通常、プロバイダーエッジ（PE））に接続するリンクに適切なセットアップがプロビジョニングされ、それによりデータ交換が成功することが想定されています。この必要なプロビジョニングは、このドキュメントでは「アタッチメント回路」（AC）と呼ばれ、基礎となるリンクは「ベアラー」と呼ばれます。
When a customer requests a new service, that service can be associated with existing ACs or may require the instantiation of new ACs. Whether these ACs are dedicated to a particular service or shared among multiple services depends on the specific deployment.
顧客が新しいサービスを要求する場合、そのサービスは既存のACSに関連付けられるか、新しいACSのインスタンス化が必要になる場合があります。これらのACが特定のサービスに専念するか、複数のサービス間で共有されているかは、特定の展開に依存します。
Examples of ACs are depicted in Figure 1. A Customer Edge (CE) may be realized as a physical node or a logical entity. From the network's perspective, a CE is treated as a peer Service Attachment Point (SAP) [RFC9408]. CEs can be dedicated to a single service (e.g., Layer 3 Virtual Private Network (VPN) or Layer 2 VPN) or can host multiple services (e.g., SFs [RFC7665]). A single AC, as viewed by the network provider, may be bound to one or more peer SAPs (e.g., "CE1" and "CE2"). For instance, as discussed in [RFC4364], multiple CEs can attach to a PE over the same AC. This approach is typically deployed when the Layer 2 infrastructure between the CE and the network supports a multipoint service. A single CE may also terminate multiple ACs (e.g., "CE3" and "CE4"), which may be carried over the same or distinct bearers.
ACSの例を図1に示します。顧客エッジ（CE）は、物理ノードまたは論理エンティティとして実現される場合があります。ネットワークの観点から見ると、CEはピアサービスアタッチメントポイント（SAP）[RFC9408]として扱われます。CESは、単一のサービス（レイヤー3仮想プライベートネットワーク（VPN）またはレイヤー2 VPNなど）に専念するか、複数のサービス（SFS [RFC7665]など）をホストすることができます。ネットワークプロバイダーによって表示される単一のACは、1つ以上のピアSAP（「CE1」および「CE2」など）にバインドされる場合があります。たとえば、[RFC4364]で説明したように、複数のCESが同じACを介してPEに付着できます。このアプローチは通常、CEとネットワークの間のレイヤー2インフラストラクチャがマルチポイントサービスをサポートするときに展開されます。単一のCEは、複数のACS（「CE3」および「CE4」など）を終了する場合があります。

This document specifies a common module ("ietf-ac-common") for ACs (Section 5). The module is designed to be reusable by other models, thereby ensuring consistent AC structures among modules that manipulate ACs. For example, the common module can be reused by service models to expose AC as a Service (ACaaS) (e.g., [RFC9834]) or by service models that require binding a service to a set of ACs (e.g., RFC 9543 Network Slice Service [YANG-NSS])). It can also be used by network models to provision ACs (e.g., [RFC9835]) and device models, among others.
このドキュメントは、ACS（セクション5）の共通モジュール（「IETF-AC-Common」）を指定します。このモジュールは、他のモデルで再利用可能になるように設計されているため、ACSを操作するモジュール間の一貫したAC構造を保証します。たとえば、一般的なモジュールは、サービスモデル（ACAAS）（例えば[RFC9834]）としてACを露出させるサービスモデルによって再利用できます。または、サービスをACSのセット（RFC 9543ネットワークスライスサービス[YANG-NSS]など）にバインドする必要があるサービスモデルが必要です。また、ネットワークモデルで使用して、ACS（[RFC9835]など）やデバイスモデルなどをプロビジョニングすることもできます。
The common AC module eases data inheritance between modules (e.g., from service to network models as per [RFC8969]).
一般的なACモジュールは、モジュール間のデータ継承を容易にします（たとえば、[RFC8969]に従ってサービスからネットワークモデルまで）。
The YANG data model in this document conforms to the Network Management Datastore Architecture (NMDA) defined in [RFC8342].
このドキュメントのYangデータモデルは、[RFC8342]で定義されているネットワーク管理データストアアーキテクチャ（NMDA）に準拠しています。
The meanings of the symbols in the YANG tree diagrams are defined in [RFC8340].
ヤンツリー図のシンボルの意味は、[RFC8340]で定義されています。
LxSM refers to both the L2VPN Service Model (L2SM) [RFC8466] and the L3VPN Service Model (L3SM) [RFC8299].
LXSMは、L2VPNサービスモデル（L2SM）[RFC8466]とL3VPNサービスモデル（L3SM）[RFC8299]の両方を指します。
LxNM refers to both the L2VPN Network Model (L2NM) [RFC9291] and the L3VPN Network Model (L3NM) [RFC9182].
LXNMは、L2VPNネットワークモデル（L2NM）[RFC9291]とL3VPNネットワークモデル（L3NM）[RFC9182]の両方を指します。
This document uses the following term:
このドキュメントでは、次の用語を使用しています。
Bearer:
ベアラー：
A physical or logical link that connects a CE (or site) to a provider network.
CE（またはサイト）をプロバイダーネットワークに接続する物理的または論理的なリンク。
A bearer can be a wireless or wired link. One or multiple technologies can be used to build a bearer. The bearer type can be specified by a customer.
ベアラーは、ワイヤレスまたは有線リンクにすることができます。1つまたは複数のテクノロジーを使用して、担い手を構築できます。ベアラーのタイプは、顧客が指定できます。
The operator allocates a unique bearer reference to identify a bearer within its network (e.g., customer line identifier). Such a reference can be retrieved by a customer and then used in subsequent service placement requests to unambiguously identify where a service is to be bound.
オペレーターは、ネットワーク内のベアラーを識別するためのユニークなベアラーの参照を割り当てます（例：カスタマーライン識別子）。このようなリファレンスは、顧客が取得し、その後のサービス配置リクエストで使用して、サービスがどこにバインドされるかを明確に識別できます。
The concept of bearer can be generalized to refer to the required underlying connection for the provisioning of an AC.
ベアラーの概念は、ACのプロビジョニングに必要な根本接続を参照するために一般化できます。
One or multiple ACs may be hosted over the same bearer (e.g., multiple Virtual Local Area Networks (VLANs) on the same bearer that is provided by a physical link).
1 つまたは複数の AC は、同じベアラ (たとえば、物理リンクによって提供される同じベアラ上の複数の仮想ローカル エリア ネットワーク (VLAN)) 上でホストされる場合があります。
The names of data nodes are prefixed using the prefix associated with the corresponding imported YANG module as shown in Table 1.

The "ietf-ac-common" module is imported by the "ietf-bearer-svc", "ietf-ac-svc", and "ietf-ac-ntw" modules. Bearers managed using the "ietf-bearer-svc" module may be referenced by service ACs managed using the "ietf-ac-svc" module. Similarly, a bearer managed using the "ietf-bearer-svc" module may list the set of ACs that use that bearer. To facilitate correlation between an AC service request and the actual AC provisioned in the network, "ietf-ac-ntw" leverages the AC references exposed by the "ietf-ac-svc" module. Furthermore, to bind Layer 2 VPN or Layer 3 VPN services with ACs, the "ietf-ac-glue" module augments the LxSM and LxNM with AC service references exposed by the "ietf-ac-svc" module and AC network references exposed by the "ietf-ac-ntw" module.
「IETF-AC-Common」モジュールは、「IETF-Bearer-SVC」、「IETF-AC-SVC」、および「IETF-AC-NTW」モジュールによってインポートされます。「IETF-BEARER-SVC」モジュールを使用して管理されたベアラーは、「IETF-AC-SVC」モジュールを使用して管理されたサービスACSによって参照できます。同様に、「IETF-BEARER-SVC」モジュールを使用して管理したベアラーは、そのベアラーを使用するACSのセットをリストできます。ACサービスリクエストとネットワークでプロビジョニングされた実際のACとの相関を促進するために、「IETF-AC-NTW」が「IETF-AC-SVC」モジュールによって公開されたAC参照を活用します。さらに、ACSを使用したレイヤー2 VPNまたはレイヤー3 VPNサービスをバインドするために、「IETF-AC-GLUE」モジュールは、「IETF-AC-SVC」モジュールとACネットワーク参照によって「IETF-AC-SVC」モジュールとACネットワーク参照が「IETF-AC-NTW」モジュールによって公開されたACサービス参照を使用してLXSMとLXNMを増強します。

Routing parameters & Operations, Administration, and Maintenance (OAM) (Figure 6):
ルーティングパラメーターと操作、管理、およびメンテナンス（OAM）（図6）：
In addition to static routing, the module supports the following routing protocols: BGP [RFC4271], OSPF [RFC4577] [RFC6565], IS-IS [ISO10589][RFC1195][RFC5308], and RIP [RFC2453]. For all supported routing protocols, 'address-family' indicates whether IPv4, IPv6, or both address families are to be activated. For example, this parameter is used to determine whether RIPv2 [RFC2453], RIP Next Generation (RIPng), or both are to be enabled [RFC2080]. More details about supported routing groupings are provided hereafter:
静的ルーティングに加えて、モジュールは次のルーティング プロトコルをサポートします: BGP [RFC4271]、OSPF [RFC4577] [RFC6565]、IS-IS [ISO10589][RFC1195][RFC5308]、および RIP [RFC2453]。サポートされているすべてのルーティング プロトコルについて、「address-family」は、IPv4、IPv6、または両方のアドレス ファミリをアクティブにするかどうかを示します。たとえば、このパラメータは、RIPv2 [RFC2453]、RIP Next Generation (RIPng)、またはその両方を有効にするかどうかを決定するために使用されます [RFC2080]。サポートされているルーティング グループの詳細については、以下で説明します。
Authentication:
認証：
These groupings include the required information to manage the authentication of OSPF, IS-IS, BGP, and RIP. The groupings support local specification of authentication keys and the associated authentication algorithm to accommodate legacy implementations that do not support key chains [RFC8177].
これらのグループには、OSPF、IS-IS、BGP、およびRIPの認証を管理するために必要な情報が含まれます。グループは、認証キーと関連する認証アルゴリズムのローカル仕様をサポートして、キーチェーン[RFC8177]をサポートしないレガシーの実装に対応します。
Note that this version of the common AC model covers authentication options that are common to both OSPFv2 [RFC4577] and OSPFv3 [RFC6565]; as such, the model does not support [RFC4552].
一般的なACモデルのこのバージョンは、OSPFV2 [RFC4577]とOSPFV3 [RFC6565]の両方に共通の認証オプションをカバーしていることに注意してください。そのため、モデルは[RFC4552]をサポートしていません。
Similar to [RFC9182], this version of the common AC model assumes that parameters specific to the TCP Authentication Option (TCP-AO) are preconfigured as part of the key chain that is referenced in the model. No assumption is made about how such a key chain is preconfigured. However, the structure of the key chain should cover data nodes beyond those in [RFC8177], mainly SendID and RecvID (Section 3.1 of [RFC5925]).
[RFC9182]と同様に、このバージョンの共通ACモデルは、TCP認証オプション（TCP-AO）に固有のパラメーターが、モデルで参照されているキーチェーンの一部として事前に設定されていると仮定しています。このようなキーチェーンがどのように事前に構成されているかについての仮定はありません。ただし、キーチェーンの構造は、[RFC8177]の構造を超えてデータノードをカバーする必要があります。
BGP peer groups ('bgp-peer-group-without-name' and 'bgp-peer-group-with-name'):
BGPピアグループ（ 'BGP-PEER-GROUP-WithOut-Name'および 'BGP-PEER-GROUP-WITH-NAME'）：
Includes a set of parameters to identify a BGP peer group. Such a group can be defined by providing a local Autonomous System Number (ASN), a customer's ASN, and the address families to be activated for this group. BGP peer groups can be identified by a name ('bgp-peer-group-with-name').
BGPピアグループを識別するパラメーターのセットが含まれています。このようなグループは、ローカル自律システム番号（ASN）、顧客のASN、およびこのグループのアクティブ化される住所ファミリを提供することにより定義できます。BGPピアグループは、名前（「BGP-PEER-GROUP WITH-NAME」）で識別できます。
Basic OSPF and IS-IS parameters ('ospf-basic' and 'isis-basic'):
基本的なOSPFおよびIS-ISパラメーター（「OSPF-Basic」および「ISIS-Basic」）：
These groupings include the minimal set of routing configuration that is required for the activation of OSPF and IS-IS.
これらのグループには、OSPFおよびIS-ISのアクティブ化に必要なルーティング構成の最小セットが含まれます。
Static routing:
静的ルーティング：
Parameters to configure an entry or a list of IP static routing entries.
エントリまたはIP staticルーティングエントリのリストを構成するパラメーター。
The 'redundancy-group' grouping lists the groups to which an AC belongs [RFC9181]. For example, the 'group-id' is used to associate redundancy or protection constraints of ACs.
「冗長グループ」グループには、ACが属するグループ[RFC9181]がリストされています。たとえば、「Group-ID」は、ACSの冗長性または保護の制約を関連付けるために使用されます。

Bandwidth parameters (Figure 7):
帯域幅パラメーター（図7）：
Bandwidth parameters can be represented using the Committed Information Rate (CIR), the Excess Information Rate (EIR), or the Peak Information Rate (PIR).
帯域幅パラメータは、認定情報レート (CIR)、超過情報レート (EIR)、またはピーク情報レート (PIR) を使用して表すことができます。
These parameters can be provided per bandwidth type. Type values are taken from [RFC9181]. For example, the following values can be used:
これらのパラメーターは、帯域幅タイプごとに提供できます。タイプ値は[RFC9181]から取得されます。たとえば、次の値を使用できます。
'bw-per-cos':
'BW-Per-Cos'：
The bandwidth is per Class of Service (CoS).
帯域幅はサービス クラス (CoS) ごとに異なります。
'bw-per-site':
「bw-per-site」：
The bandwidth is for all ACs that belong to the same site.

The "ietf-ac-common" YANG module defines a data model that is designed to be accessed via YANG-based management protocols, such as NETCONF [RFC6241] and RESTCONF [RFC8040]. These protocols have to use a secure transport layer (e.g., SSH [RFC4252], TLS [RFC8446], and QUIC [RFC9000]) and have to use mutual authentication.
「IETF-AC-Common」Yangモジュールは、NetConf [RFC6241]やRestConf [RFC8040]などのYangベースの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たデータモデルを定義します。これらのプロトコルは、安全な輸送層（例：SSH [RFC4252]、TLS [RFC8446]、およびQUIC [RFC9000]）を使用し、相互認証を使用する必要があります。
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、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特定のNetConfまたはRestConfユーザーのアクセスを制限する手段を提供します。
The YANG module defines a set of identities, types, and groupings. These nodes are intended to be reused by other YANG modules. The module by itself does not expose any data nodes that are writable, data nodes that contain read-only state, or RPCs. As such, there are no additional security issues related to the YANG module that need to be considered.
Yangモジュールは、一連のアイデンティティ、タイプ、およびグループ化を定義します。これらのノードは、他のヤンモジュールによって再利用されることを目的としています。モジュール自体は、書き込み可能なデータノード、読み取り専用状態を含むデータノード、またはRPCを公開しません。そのため、検討する必要があるYangモジュールに関連する追加のセキュリティ問題はありません。
Modules that use the groupings that are defined in this document should identify the corresponding security considerations. For example, reusing some of these groupings will expose privacy-related information (e.g., 'ipv6-lan-prefixes' or 'ipv4-lan-prefixes'). Disclosing such information may be considered a violation of the customer-provider trust relationship.
このドキュメントで定義されているグループを使用するモジュールは、対応するセキュリティ上の考慮事項を識別する必要があります。たとえば、これらのグループ化の一部を再利用すると、プライバシー関連の情報が公開されます（たとえば、「IPv6-Lan-Prefixes」または「IPv4-Lan-Prefixes」）。そのような情報の開示は、顧客プロバイダーの信頼関係の違反と見なされる場合があります。
Several groupings ('bgp-authentication', 'ospf-authentication', 'isis-authentication', and 'rip-authentication') rely upon [RFC8177] for authentication purposes. As such, modules that will reuse these groupings will inherit the security considerations discussed in Section 5 of [RFC8177]. Also, these groupings support supplying explicit keys as strings in ASCII format. The use of keys in hexadecimal string format would afford greater key entropy with the same number of key-string octets. However, such a format is not included in this version of the common AC model, because it is not supported by the underlying device modules (e.g., [RFC8695]).
いくつかのグループ（「bgp-authentication」、「ospf-authentication」、「isis-authentication」、および 'rip-authentication'）は、認証を目的として[RFC8177]に依存しています。そのため、これらのグループ化を再利用するモジュールは、[RFC8177]のセクション5で説明されているセキュリティ上の考慮事項を継承します。また、これらのグループ化は、ASCII形式の文字列として明示的なキーを提供することをサポートします。ヘキサデシマルストリング形式でキーを使用すると、同じ数のキーストリングオクテットでより大きなキーエントロピーが得られます。ただし、このような形式は、基礎となるデバイスモジュール（[RFC8695]など）によってサポートされていないため、このバージョンの一般的なACモデルには含まれていません。
