Moving Generic Associated Channel (G-ACh) IANA registries to a new
registry
draft-lcap-mpls-moving-iana-registries-00
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)" registry under the "Multiprotocol Label Switching
Architecture (MPLS)" heading. This is an update to RFC 5586
[RFC5586].
This document also updates RFC 6374, RFC 6428, RFC 6378, RFC 6427,
RFC-ietf-mpls-gach-adv-08, and
RFC-ietf-mpls-tp-ethernet-addressing-08.

Internet-Draft Creating G-ACh registries August 2013
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 registry" in the "Multiprotocol Label
Switching Architecture (MPLS)" name space. This is an update to RFC
RFC 5586 [RFC5586].
Further, the "Pseudowire Associated Channel Types" registry is
renamed to "MPLS Generalized Associated Channel (G-ACh) Types
(including Pseudowire Associated Channel Types)" to make its
generalized status explicit, and is moved into the newly created
registry.
Additionally, RFC 6374 [RFC6374], RFC 6428 [RFC6428], RFC 6378]
[RFC6378], RFC 6427 [RFC6427], RFC-ietf-mpls-gach-adv-08
[I-D.ietf-mpls-gach-adv], and RFC-ietf-mpls-tp-ethernet-addressing-08
[I-D.ietf-mpls-tp-ethernet-addressing] 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.
Editor's note:
Need to fix the references to RFC-ietf-mpls-gach-adv-08 and RFC-ietf-
mpls-tp-ethernet-addressing-08
2. IANA Considerations
2.1. Creation of a new Generic Associated Channel (G-ACh) IANA registry
IANA is requested to create a new "Generic Associated Channel
(G-ACh)" registry under the "Multiprotocol Label Switching
Architecture (MPLS)" heading.
2.2. Renaming the Pseudowire Associated Channel Types registry
This document renames the "Pseudowire Associated Channel Types" [PWE-
IANA] into "MPLS Generalized Associated Channel (G-ACh) Types
(including Pseudowire Associated Channel Types)". This registry is
included as the first registry because any additional registration is
dependent upon the Associated Channel Header Type.

Internet-Draft Creating G-ACh registries August 2013
2.3. Consolidating G-ACh registries
This document further updates the following RFCs by moving the G-ACh
related registrations to a common "MPLS Generic Associated Channel
Parameters" registry:
o From the PWE Registry [IANA-PWE3]:
* MPLS Generalized Associated Channel (G-ACh) Types [RFC5586]
* G-ACh Advertisement Protocol Application Registry
[I-D.ietf-mpls-gach-adv]
* G-ACh Advertisement Protocol TLV Registry
[I-D.ietf-mpls-gach-adv]
* G-ACh Advertisement Protocol: Ethernet Interface Parameters
[I-D.ietf-mpls-tp-ethernet-addressing]
* CC/CV MEP-ID TLV Registry [RFC6428]
o From the LSP Ping 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 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]
All the sub-registries are moved from "Multiprotocol Label
Switching (MPLS) Operations, Administration, and Management (OAM)
Parameters" registry. The IANA is therefore requested to remove
this registry.

3. RFC Updates
This document updates [RFC 5586] renaming the "Pseudowire Associated
Channel Types" [PWE-IANA] into "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 registrations to a common "MPLS Generic Associated Channel
(G-ACh)" registry: RFC 6374, RFC 6428, RFC 6378, RFC 6427, RFC-ietf-
mpls-gach-adv-08, and RFC-ietf-mpls-tp-ethernet-addressing-08.
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.
