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

1. Introduction
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].
Andersson & Pignataro Standards Track [Page 2]
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.
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.
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.
2. IANA Considerations
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.
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].

2.3. Consolidating G-ACh Registries
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.
o From the PWE Parameters Registry [IANA-PWE3]:
* MPLS Generalized Associated Channel (G-ACh) Types [RFC5586]
* CC/CV MEP-ID TLV Registry [RFC6428]
o From the MPLS LSP Ping Parameters Registry [IANA-LSP-Ping]:
* Measurement Timestamp Type [RFC6374]
* Loss/Delay Measurement Control Code: Query Codes [RFC6374]
* Loss/Delay Measurement Control Code: Response Codes [RFC6374]
* MPLS Loss/Delay Measurement TLV Object [RFC6374]
o From the MPLS OAM Parameters Registry [IANA-MPLS-OAM]:
* MPLS Fault OAM Message Type Registry [RFC6427]
* MPLS Fault OAM Flag Registry [RFC6427]
* MPLS Fault OAM TLV Registry [RFC6427]
* MPLS PSC Request Registry [RFC6378]
* MPLS PSC TLV Registry [RFC6378]
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.
3. RFC Updates
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)".
Andersson & Pignataro Standards Track [Page 4]
RFC 7214 Creating G-ACh registries May 2014
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.
4. Security Considerations
The IANA instructions in this document do not directly introduce any
new security issues.
5. Acknowledgements
