A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the TCP Maintenance and Minor Extensions Working Group of the IETF.
Title : TCP User Timeout Option
Author(s) : L. Eggert, F. Gont
Filename : draft-ietf-tcpm-tcp-uto-01.txt
Pages : 14
Date : 2005-7-19
The TCP user timeout controls how long transmitted data may remain
unacknowledged before a connection is forcefully closed. It is a
local, per-connection parameter. The advisory TCP User Timeout
Option allows conforming TCP implementations to exchange their local
user timeouts. This exchange provides an in-protocol mechanism to
coordinate raising or lowering the two user timeouts of a connection.
Increase the user timeouts allows established TCP connections to
survive extended periods of disconnection. Decreasing user timeouts
allows busy servers to explicitly notify their clients that they will
maintain the connection state only across short periods of
disconnection.

In the body type:
"FILE /internet-drafts/draft-ietf-tcpm-tcp-uto-01.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.
