A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Path MTU Discovery Working Group of the IETF.
Title : Path MTU Discovery
Author(s) : M. Mathis, et. al.
Filename : draft-ietf-pmtud-method-00.txt
Pages : 20

[@@ To be rewritten]
This document describes Path MTU Discovery for the Internet. It is
largely derived from RFC 1191 and RFC 1981, which describe ICMP based
Path MTU Discovery for IP versions 4 and 6, plus a robust new
algorithm.
The general strategy of the new algorithm is to start with a small
MTU and probe upward, testing successively larger MTUs by probing
with single packets. If the probe is successfully delivered, then
the MTU is raised. If the probe is lost, it is treated as an MTU
limitation and not as a congestion signal.

In the body type:
"FILE /internet-drafts/draft-ietf-pmtud-method-00.txt".
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.
