Title : Limited Slow-Start for TCP with Large Congestion
Author(s) : S. Floyd
Filename : draft-ietf-tsvwg-slowstart-00.txt
Pages : 7
Date : 2003-7-25
This note describes an optional modification for TCP's slow-start for
use with TCP connections with large congestion windows. For TCP
connections that are able to use congestion windows of thousands (or
tens of thousands) of MSS-sized segments (for MSS the sender's
MAXIMUM SEGMENT SIZE), the current slow-start procedure can result in
increasing the congestion window by thousands of segments in a single
round-trip time. Such an increase can easily result in thousands of
packets being dropped in one round-trip time. This is often counter-
productive for the TCP flow itself, and is also hard on the rest of
the traffic sharing the congested link. This note describes Limited
Slow-Start as an optional mechanism for limiting the number of
segments by which the congestion window is increased for one window
of data during slow-start, in order to improve performance for TCP
connections with large congestion windows.

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.
