A new Request for Comments is now available in online RFC libraries. RFC 7026 Title: Retiring TLVs from the Associated Channel Header of the MPLS Generic Associated Channel Author: A. Farrel, S. Bryant Status: Standards Track Stream: IETF Date: September 2013 Mailbox: adrian@olddog.co.uk, stbryant@cisco.com Pages: 5 Characters: 9297 Updates: RFC 5586 I-D Tag: draft-ietf-mpls-retire-ach-tlv-03.txt URL: http://www.rfc-editor.org/rfc/rfc7026.txt 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. This document is a product of the Multiprotocol Label Switching Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements.
