Hi, I revived this draft and cut out a bunch of stuff that detracted from the main idea. The main idea is that a link that is suffering from link adaptation overload can send an advisory message to the original source asking that it reduce the size of the packets it sends - even if the size is less than 1280 bytes. This is an advisory message and does not necessarily indicate packet loss. The message is also backward compatible with legacy nodes.

Title : IPv6 Path MTU Interactions With Link Adaptation Author(s) : Fred L. Templin Filename : draft-templin-6man-linkadapt-00.txt Pages : 6 Date : 2013-09-09 Abstract: IPv6 intentionally deprecates fragmentation by routers in the network. Instead, links with restricting Maximum Transmission Units (MTUs) must either drop each too-large packet and return an ICMPv6 Packet Too Big (PTB) message or perform link-specific fragmentation and reassembly (also known as "link adaptation") at a layer below IPv6. This latter category of links is often performance-challenged to accommodate steady-state link adaptation. This document therefore proposes an update to the base IPv6 specification to better accommodate links that require link-specific adaptation to meet the IPv6 minimum MTU of 1280 bytes.
