	Title		: Evaluation of RFC 4138

    Forward-RTO recovery (F-RTO) specified in RFC 4138 is an algorithm
    for detecting a spurious retransmission timeout with TCP and SCTP.
    This document describes the advantages of F-RTO and summarizes the
    experience in its implementations and the experiments conducted with
    it. By analyzing the implications of the spurious retransmission
    timeouts on the regular RTO recovery and Forward-RTO recovery
    algorithm, including a detailed corner case analysis, it shows that
    F-RTO does not have negative impact on the network when used with an
    appropriate response algorithm even in the rare cases where F-RTO
    falsely declares a retransmission timeout spurious. It concludes
    with a recommendation that F-RTO is to be advanced to the standards
    track.

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.
