Hi Joe, I decided to revive the draft on sending soft PTBs (see below). The diffs show that there were some minimal but important changes from the previous version.
Like what is in both the GRE and AERO drafts, this is only part of the bigger picture ; multiple components need to come together to complete the big picture. Thanks - Fred [email protected] --- A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : IPv6 Path MTU Interactions With Link Adaptation Author : Fred L. Templin Filename : draft-templin-6man-linkadapt-02.txt Pages : 5 Date : 2015-02-27 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.
