	Title		: HighSpeed TCP for Large Congestion Windows
	Author(s)	: S. Floyd
	Filename	: draft-ietf-tsvwg-highspeed-00.txt
	Pages		: 36
	Date		: 2003-7-25
This document proposes HighSpeed TCP, a modification to TCP's
congestion control mechanism for use with TCP connections with
large congestion windows.  The congestion control mechanisms
of the current Standard TCP constrains the congestion windows
that can be achieved by TCP in realistic environments.  For
example, for a Standard TCP connection with 1500-byte packets
and a 100 ms round-trip time, achieving a steady-state
throughput of 10 Gbps would require an average congestion
window of 83,333 segments, and a packet drop rate of at most
one congestion event every 5,000,000,000 packets (or
equivalently, at most one congestion event every 1 2/3 hours).
This is widely acknowledged as an unrealistic constraint.  To
address this limitation of TCP, this document proposes
HighSpeed TCP, and solicits experimentation and feedback from
the wider community.

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.
