       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].

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.
