Congestion Control for High-Bandwidth-Delay-Product Networks:
XCP vs. HighSpeed TCP and QuickStart,
ICIR Wednesday Lunch, September 11, 2002
Srikanth Sundarrajan added QuickStart to the NS simulator in 2002.
The initial validation test is
"./test-all-quickstart" in tcl/test.
Pasi Sarolahti updated the Quick-Start implementation in September 2004,
to conform to draft-amit-quick-start-03.txt.
The default values for
the Quick-Start parameters in ns-default.tcl were updated on 2/25/2005.
With the NS defaults from 2/25/2005, the router approves Quick-Start requests
when the link utilization will remain below 85%.
The router measures the current link utilization by measuring the
utilization over five 200-ms time slots, and taking the peak
- What do measurement studies show about underutilized end-to-end paths,
where QuickStart would be of the most benefit?
Are there a lot of underutilized paths? Only in Intranets?
Or only for not-at-home users with very good Internet connectivity?
Are there likely to be more underutilized paths in the future?
- What are the range of options for more precise algorithms in routers,
for those routers that are willing to do a little more work, or to keep
a little more state?
Other Proposals for Positive Feedback from Routers:
(Some of these proposals are rather different from QuickStart, in that
they allow more precise control and faster ramping-up than TCP, but they
don't enable a large initial window.)
