Title : PMTU-Options: Path MTU Discovery Using Options
Author(s) : M. Welzl
Filename : draft-welzl-pmtud-options-00.txt
Pages : 20
Date : 2003-11-24
This document describes an experimental enhancement of Path MTU
Discovery that has the potential of reducing loss, speeding up
convergence, reducing load in routers which would otherwise need to
generate a large amount of ICMP messages, and alleviating certain
additional problems (interactions with tunnels, Black Hole
Detection). The idea is to use an IP Option which queries routers for
their MTU before starting a Path MTU Discovery process. The result
retrieved in this is used as an upper limit for Path MTU Discovery.
To this end, it is fed back to the source either at the packetization
layer (recommended) or at the IP layer.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
