Stewart, Adrian and all,
Late is better than never!
(I must admit that I never understood the need for generic TLVs preceding G-ACH messages.
Looks as I was not the only one, since, so far, nobody has defined any such...)
Hopefully the WG and the IESG will handle this I-D fast enough.
Regards,
Sasha

A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Retiring TLVs from the Associated Channel Header of the MPLS Generic Associated Channel
Author(s) : Adrian Farrel
Stewart Bryant
Filename : draft-farbryantrel-mpls-retire-ach-tlv-00.txt
Pages : 4
Date : 2013-05-07
Abstract:
The MPLS Generic Associated Channel (G-ACh) is a generalization of
the applicability of the Pseudowire (PW) Associated Channel Header
(ACH). RFC 5586 defines the concept of Type-Length-Variable (TLV)
constructs that can be carried in messages on the G-ACh by placing
them in the ACH.
No Associated Channel Type yet defined uses a TLV. Furthermore, it
is believed that handling TLVs in hardware introduces significant
problems to the fast-path, and since G-ACh messages are intended to
be processed substantially in hardware, the use of TLVs in
undesirable.
This document updates RFC 5586 by retiring ACH TLVs and removing the
associated registry.
