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-05.txt
Pages : 16
Date : 2007-3-8
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. This document specifies a new TCP
option - the TCP User Timeout Option - that allows one end of a TCP
connection to advertise its current user timeout value. This
information allows the other end to adapt its user timeout
accordingly. Increasing the user timeouts on both ends of a TCP
connection allows it to survive extended periods without end-to-end
connectivity. Decreasing the user timeouts allows busy servers to
explicitly notify their clients that they will maintain the
connection state only for a short time without connectivity.

In the body type:
"FILE /internet-drafts/draft-ietf-tcpm-tcp-uto-05.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.
