Simulations for the "Estimating Arrival Rates" paper

The page contains the tcl scripts used for running the simulations in the following paper:

[FFT98] Sally Floyd, Kevin Fall, and Kinh Tieu, Estimating Arrival Rates from the RED Packet Drop History , April 1998.

These scripts run with ns version 2.1b2, and should run with any later releases of ns-2.

Simulation 1:

The simulations for Figure 3-6, "Comparing drop metrics for forced and random packet drops", "The combined drop metric for all packet drops, for simulation 1", "The percent of packets dropped, number of drops in a sample, and length of each sample, for simulation 1", and "Statistics for the high-bandwidth flow from each sample, for simulation 1", can be run in ns-2 with FlowAllA.v2.com and supporting scripts Flow4A.v2.tcl, FlowsA.v2.tcl, Setred.v2.tcl, and bound.tcl.

The simulations for Figure 7, "Statistics for the high-bandwidth flow from each sample, for 100 runs of simulation 1", can be run with FlowAllA1.v2.com. The S-file for displaying the results is Dist.com.

Simulation 2:

The simulations for Figure 8-9, "The combined drop metric, percent of packets dropped, number of drops in a sample, and length of each sample, for simulation 2" and "Statistics for the high-bandwidth flow from each sample, for simulation 2", can be run in ns-2 with FlowAllB.v2.com and supporting scripts Flow4B.v2.tcl, FlowsA.v2.tcl, Setred.v2.tcl, and bound.tcl.

The simulations for Figure 10, "Statistics for the high-bandwidth flow from each sample, for 100 runs of simulation 2", can be run with FlowAllB1.v2.com. The S-file for displaying the results is Dist.com.

Simulation 3:

The simulations for Figure 11-12, "The combined drop metric, percent of packets dropped, number of drops in a sample, and length of each sample, for simulation 3" and "Statistics for the high-bandwidth flow from each sample, for simulation 3", can be run in ns-2 with FlowAllC.v2.com and supporting scripts Flow4C.v2.tcl, FlowsA.v2.tcl, Setred.v2.tcl, and bound.tcl.

The simulations for Figure 13, "Statistics for the high-bandwidth flow from each sample, for 100 runs of simulation 3", can be run with FlowAllC1.v2.com. The S-file for displaying the results is Dist.com.

Simulations in the appendix: The simulations in the appendix were done with an older version of the simulator.
