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

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.
