Title : The IPv6 MTU Label
Author : Jeroen Massar
Filename : draft-massar-v6man-mtu-label-02.txt
Pages : 12
Date : 2014-11-13
Abstract:
This document redefines the use of the IPv6 Flow Label field to allow
specification of the lowest MTU on a path that the packet travels,
thus in most cases avoiding the need for performing Path MTU
Discovery and the round-trip penalty that that occurs for processing
the ICMPv6 PTB and retransmitting the packets involved.
This specification allows graceful decrease of MTU so that large and
non-standard MTU sizes can safely be used on the Internet.
[[A1: Obsoleting the IPv6 Flow Label and replacing it completely with
this field might be a better option than keeping it defined as an
IPv6 Flow Label field and allowing existing flows to exist. --JM]]
[[A2: A better name than "IPv6 MTU Label" is requested as it is not
really a "Label". --JM]]
