Moving Generic Associated Channel (G-ACh) IANA Registries to a New
Registry
draft-ietf-mpls-moving-iana-registries-04
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 RFC 6374, RFC 6428, RFC 6378, RFC 6427,
RFC-ietf-mpls-gach-adv, and RFC-ietf-mpls-tp-ethernet-addressing.

Internet-Draft Creating G-ACh registries January 2014
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 is
needed to get a single view of the G-ACh registries, to simplify
future assignments, and to avoid potential conflicts. 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
[I-D.ietf-mpls-gach-adv], and RFC-ietf-mpls-tp-ethernet-addressing
[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 and RFC-ietf-
mpls-tp-ethernet-addressing
2. IANA Considerations
IANA is requested to add this document as a reference for any
registry that is moved or renamed as a result of actions requested by
this document.
IANA is also requested to replace 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 is requested to create a new "Generic Associated Channel (G-ACh)
Andersson & Pignataro Expires July 30, 2014 [Page 3]
Internet-Draft Creating G-ACh registries January 2014
Parameters" registry under the "Multiprotocol Label Switching
Architecture (MPLS)" heading. 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] into "MPLS Generalized Associated Channel
(G-ACh) Types (including Pseudowire Associated Channel Types)". This
registry is moved and included as the first registry 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: [I-D.ietf-mpls-gach-adv],
[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 G-ACh
related registries to the common "MPLS 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]
* 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 MPLS LSP Ping Parameters Registry [IANA-LSP-Ping]:
* Measurement Timestamp Type [RFC6374]
* Loss/Delay Measurement Control Code: Query Codes [RFC6374]
Andersson & Pignataro Expires July 30, 2014 [Page 4]
Internet-Draft Creating G-ACh registries January 2014
* 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] are moved from
"Multiprotocol Label Switching (MPLS) Operations, Administration,
and Management (OAM) Parameters" registry. The IANA is therefore
requested to remove the "MPLS OAM" registry.
3. RFC Updates
This document updates [RFC5586] renaming the "Pseudowire Associated
Channel Types" [IANA-PWE3] 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 registries to a common "MPLS Generic Associated Channel
(G-ACh) Parameters" registry: RFC 6374, RFC 6428, RFC 6378, RFC 6427,
RFC-ietf-mpls-gach-adv, and RFC-ietf-mpls-tp-ethernet-addressing.
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
The authors want to thank Amanda Barber and Scott Bradner for review
and valuable comments.
