	Title		: Making TCP Robust Against Delay Spikes

We suggest a more conservative management of TCP's retransmit timer,
and a more careful response of the TCP sender to duplicate ACKs that
arrive after a timeout. The former reduces the risk of triggering
spurious timeouts, while the latter eliminates potentially
unnecessary retransmits. Although, we believe that these suggestions
are permitted (although not explicitly) by RFC2581 and RFC2988, they
do not seem to be widely known nor deployed in existing TCP
implementations. We therefore want to make implementers aware of
these choices.

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.
