Internet Engineering Task Force (IETF) L. Andersson Request for Comments: 7214 Huawei Updates: 5586, 6374, 6378, 6427, 6428 C. Pignataro Category: Standards Track Cisco ISSN: 2070-1721 May 2014
Moving Generic Associated Channel (G-ACh) IANA Registries to a New Registry
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.
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].

RFC 7214 Creating G-ACh registries May 2014
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.
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.
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 has replaced all the relocated registries with pointers to the new URL or with a redirect.
2.1. Creation of a New Generic Associated Channel (G-ACh) Parameters IANA Registry
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.
2.2. Renaming and Moving the Pseudowire Associated Channel Types Registry
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.
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.
