The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'Retiring TLVs from the Associated Channel Header of the MPLS Generic Associated Channel' <draft-ietf-mpls-retire-ach-tlv-02.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-07-31. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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 TLV constructs that can be carried in messages on the G-ACh by placing them in the ACH between the fixed header fields and the G-ACh message. These TLVs are called ACH TLVs No Associated Channel Type yet defined uses an ACH 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 ACH TLVs is undesirable. This document updates RFC 5586 by retiring ACH TLVs and removing the associated registry. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-mpls-retire-ach-tlv/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-mpls-retire-ach-tlv/ballot/ No IPR declarations have been submitted directly on this I-D.
