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-04.txt
Pages : 17
Date : 2006-10-25
This document specifies a new TCP option - the TCP User Timeout
Option - that allows a TCP to advertise its current user timeout for
a connection. Thus, the remote TCP may modify its local user timeout
based on knowledge of the peer's user timeout. 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. Increasing the user timeouts allows established TCP
connections to survive extended periods of disconnection. Decreasing
the 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-04.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.
