Moving Generic Associated Channel (G-ACh) IANA Registries to a New Registry
将通用关联通道（G-ACh）IANA注册表移动到新注册表
Abstract
摘要
RFC 5586 generalized the applicability of the pseudowire Associated Channel Header (PW-ACH) into the Generic Associated Channel G-ACh. However, registries and allocations of G-ACh parameters had been distributed throughout different, sometimes unrelated, registries. This document coalesces these into a new "Generic Associated Channel (G-ACh) Parameters" registry under the "Multiprotocol Label Switching Architecture (MPLS)" heading. This document updates RFC 5586.
RFC 5586将伪线相关信道头（PW-ACH）的适用性推广到通用相关信道G-ACH中。然而，G-ACh参数的登记和分配分布在不同的、有时是不相关的登记处。本文档将这些参数合并到“多协议标签交换体系结构（MPLS）”标题下的新“通用关联通道（G-ACh）参数”注册表中。本文档更新了RFC 5586。
This document also updates RFCs 6374, 6378, 6427, and 6428.

RFC 5586 generalized the PW-ACH into the G-ACh. However, registries and allocations of G-ACh namespaces had been distributed throughout different registries. This document coalesces these into a new "Generic Associated Channel (G-ACh) Parameters" registry in the "Multiprotocol Label Switching Architecture (MPLS)" name space. This reorganization achieves two purposes: it allocates the G-ACh registries in their natural place in the MPLS names space, and it provides a single view of the G-ACh registries, to simplify future assignments and avoid potential conflicts. This is an update to RFC 5586 [RFC5586].
RFC5586将PW-ACH推广到G-ACH。然而，G-ACh名称空间的注册和分配分布在不同的注册中心。本文档将这些参数合并到“多协议标签交换体系结构（MPLS）”名称空间中的新“通用关联通道（G-ACh）参数”注册表中。这种重组实现了两个目的：它在MPLS名称空间中的自然位置分配G-ACh注册表，并提供G-ACh注册表的单一视图，以简化未来的分配并避免潜在的冲突。这是对RFC 5586[RFC5586]的更新。
Further, the "Pseudowire Associated Channel Types" registry is renamed to "Generalized Associated Channel (G-ACh) Types (including Pseudowire Associated Channel Types)" to make its generalized status explicit, and it is moved into the newly created registry.
此外，将“伪线关联通道类型”注册表重命名为“广义关联通道（G-ACh）类型（包括伪线关联通道类型）”以使其广义状态显式，并将其移动到新创建的注册表中。
Additionally, RFC 6374 [RFC6374], RFC 6378 [RFC6378], RFC 6427 [RFC6427], and RFC 6428 [RFC6428] specify allocations within the G-ACh that are now moved into the new registry.
此外，RFC 6374[RFC6374]、RFC 6378[RFC6378]、RFC 6427[RFC6427]和RFC 6428[RFC6428]指定G-ACh中现在移动到新注册表中的分配。
With respect to where to find these IANA registries, the RFCs listed above are updated as indicated in Section 3; however, the registries themselves are not changed (with the exception of one being renamed). They are moved unchanged to the new registry.
关于在何处找到这些IANA登记处，上文所列的RFC如第3节所示进行了更新；但是，注册中心本身没有改变（只有一个被重命名）。它们将原封不动地移动到新的注册表中。
IANA has added this document as a reference for each registry that has been moved or renamed as a result of actions requested by this document.
IANA已添加本文档，作为由于本文档要求的操作而移动或重命名的每个注册表的参考。
IANA has replaced all the relocated registries with pointers to the new URL or with a redirect.
IANA用指向新URL的指针或重定向替换了所有重新定位的注册表。
2.1. Creation of a New Generic Associated Channel (G-ACh) Parameters IANA Registry
2.1. 在IANA注册表中创建新的通用关联通道（G-ACh）参数
IANA has created a new "Generic Associated Channel (G-ACh) Parameters" registry. This is the common registry that will include all the registries being moved in Sections 2.2 and 2.3.
IANA创建了一个新的“通用关联通道（G-ACh）参数”注册表。这是通用注册表，其中包括第2.2节和第2.3节中移动的所有注册表。
2.2. Renaming and Moving the Pseudowire Associated Channel Types Registry
2.2. 重命名和移动伪线关联通道类型注册表
This document renames the "Pseudowire Associated Channel Types" registry [IANA-PWE3] to "MPLS Generalized Associated Channel (G-ACh) Types (including Pseudowire Associated Channel Types)". This registry has been moved and included in the "Generic Associated Channel (G-ACh) Parameters" registry created in Section 2.1 because any additional registries are dependent upon the Associated Channel Header Type.
本文档将“伪线关联通道类型”注册表[IANA-PWE3]重命名为“MPLS通用关联通道（G-ACh）类型（包括伪线关联通道类型）”。此注册表已被移动并包含在第2.1节中创建的“通用关联通道（G-ACh）参数”注册表中，因为任何其他注册表都取决于关联的通道标头类型。
At the time of publishing this document and moving the registry, the following RFCs have G-ACh Types allocated: [RFC4385], [RFC5586], [RFC5718], [RFC5885], [RFC6374], [RFC6378], [RFC6426], [RFC6427], [RFC6428], [RFC6435], [RFC6478], and [RFC6671].
在发布本文档并移动注册表时，以下RFC分配了G-ACh类型：[RFC4385]、[RFC5586]、[RFC5718]、[RFC5885]、[RFC6374]、[RFC6378]、[RFC6426]、[RFC6427]、[RFC6428]、[RFC6435]、[RFC6478]和[RFC6671]。
This document further updates the following RFCs by moving the registries related to G-ACh to the common "Generic Associated Channel (G-ACh) Parameters" registry created in Section 2.1.
本文件通过将与G-ACh相关的注册表移至第2.1节中创建的通用“通用关联通道（G-ACh）参数”注册表，进一步更新了以下RFC。

* MPLS故障OAM消息类型注册表[RFC6427]
* MPLS Fault OAM Flag Registry [RFC6427]
* MPLS故障OAM标志注册表[RFC6427]

Note that all the sub-registries in [IANA-MPLS-OAM] have been removed from "Multiprotocol Label Switching (MPLS) Operations, Administration, and Management (OAM) Parameters" registry. Therefore, the IANA has removed the MPLS OAM registry, per this document.
请注意，[IANA-MPLS-OAM]中的所有子注册表已从“多协议标签交换（MPLS）操作、管理和管理（OAM）参数”注册表中删除。因此，IANA根据本文档删除了MPLS OAM注册表。
This document updates [RFC5586] renaming the "Pseudowire Associated Channel Types" [IANA-PWE3] to "MPLS Generalized Associated Channel (G-ACh) Types (including Pseudowire Associated Channel Types)".
本文档将[RFC5586]将“伪线相关信道类型”[IANA-PWE3]重命名为“MPLS通用相关信道（G-ACh）类型（包括伪线相关信道类型）”。
This document also updates the following RFCs by moving the G-ACh related registries to a common "MPLS Generic Associated Channel (G-ACh) Parameters" registry: RFCs 6374, 6378, 6427, and 6428.
本文档还通过将G-ACh相关注册表移动到公共“MPLS通用关联通道（G-ACh）参数”注册表来更新以下RFC：RFCs 6374、6378、6427和6428。
All the registries listed above are moved without any changes to their content. The reason to move them is to create on single place where it is possible to find all the G-ACh parameters.
移动上面列出的所有注册表时，不会对其内容进行任何更改。移动它们的原因是在一个地方创建，在那里可以找到所有G-ACh参数。
The IANA instructions in this document do not directly introduce any new security issues.
本文档中的IANA说明不会直接引入任何新的安全问题。
