Moving Generic Associated Channel (G-ACh) IANA Registries to a New Registry

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. 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. Additionally, RFC 6374 , RFC 6378 , RFC 6427 , and RFC 6428 specify allocations within the G-ACh that are now moved into the new registry. With respect to where to find these IANA registries, the RFCs listed above are updated as indicated in ; 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.

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 and .

This document renames the "Pseudowire Associated Channel Types" registry 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 because any additional registries are dependent upon the Associated Channel Header Type. At the time of publishing this document and moving the registry, the following RFCs have G-ACh Types allocated: , , , , , , , , , , , and .

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 . From the PWE Parameters Registry : MPLS Generalized Associated Channel (G-ACh) Types CC/CV MEP-ID TLV Registry From the MPLS LSP Ping Parameters Registry : Measurement Timestamp Type Loss/Delay Measurement Control Code: Query Codes Loss/Delay Measurement Control Code: Response Codes MPLS Loss/Delay Measurement TLV Object From the MPLS OAM Parameters Registry : MPLS Fault OAM Message Type Registry MPLS Fault OAM Flag Registry MPLS Fault OAM TLV Registry MPLS PSC Request Registry MPLS PSC TLV Registry Note that all the sub-registries in 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.

This document updates renaming the "Pseudowire Associated Channel Types" to "MPLS Generalized Associated Channel (G-ACh) Types (including Pseudowire Associated Channel Types)". 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. 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.

The IANA instructions in this document do not directly introduce any new security issues.
