Simulations for Stateful TCP Congestion Control
This page has pointers to the simulation scripts for the following paper. These simulation scripts are also available from a tar file . The README file describes the procedures for running these simulations.Standard Disclaimer:THIS SOFTWARE IS PROVIDED BY THE REGENTS AND CONTRIBUTORS ``AS IS'' AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

ACKNOLEDGEMENT: Many of the simulation scripts come from Sally Floyd's work . Thus, to obtain the figures in our papers, you have to download and install her package (the tar file ) from the same website.
These scripts may look ugly and should not be used as examples in a programming style class :(. The ns code is given in patched form.

This page will be updated constantly, should we receive any bug reports .
Some of these simulations must be run with SBSIZE in scoreboard.h set to 2048 instead of to 1024, to allow larger TCP congestion windows.
ns-2 patch for the spectrum of TCP congestion window update algorithms explored in the paper [JGMB:TR01], SIMD is also included. This patch should work for ns2.1b7&ns2.1b8a or later.
Many of the simulation scripts (specifically, for TCP compatibility and smoothness experiments) are courtesy of Sally Folyd . Thus, to obtain the figures in our papers, you have to download and install package (the tar file ) from the same website.
We now describe how to generate individual plots. We also have a integrated package (in the form of a tar file ) for ease of downloading.
Figure 8-17 require Floyd's package, so copy all the files to the directory /aimdscripts and do the following:
All the figures refer to our technical report (the extended version).
The simulation for Figure 8,9,10,11,12,13 on "TCP competing with SIMD(1/16) /AIAD" can be run with:
poly12.com , with supporting files poly12.run , poly12.run1 , poly12.tcl , bwcnt2 (compiled from bwcnt2.c) . AIAD scripts are similar and the description is omitted here.
Figure 14,15,16,17 on "Traffic smoothness" can be run with:
simd.com , with supporting files simd.run0 , simd.run1 , simd.run2 , tfrm12-poly-stoptime.tcl . Note that all of the scripts here only generate plots for SIMD.
The scripts for generating other figures are under the directory /transient , so you need to do the following:
Figure 18(a) and 18(b) (responsiveness and aggressiveness) can be generated by running resp.com and aggr.com , respectively. Related files are tcp-bin-aggr.tcl, tcp-bin-resp.tcl , topology.tcl , plot-aggr.mf , plot-resp.mf .
Figure 21 (convergence, case 1) and Figure 22 (convergence, case 2) are generated by converge.com and catchup.com , respectively. Related files are converge.tcl , catchup.tcl , and plot commands under directory /plot_cmd.
