TCPBenchmarking

Checking on how different TCP variants perform in NS2 simulation.

Completely based on paper “Simulation-based Comparisons of Tahoe, Reno, and SACK TCP” by Kevin Fall & Sally Floyd.

Simulate the network topology used by Fall and Floyd in their paper:

alt

Running simulations: (scripts, simulator code and output are attached)

Example: <TCP_TYPE> TCP - packet loss <no% of packet loss>:

  1. Go in to tahoe folder and run ‘ns tcp_drop_tahoe.tcl <no% of packet loss>’
  2. Based on <no% of packet loss> the output files will be created in the appropriate folder
  3. Go in to the appropriate folder and run cat out.tr | ../../Utils/packageplot.pl <TCP_TYPE> . It must have created three output files (ack.tahoe, dropped.tahoe, sent.tahoe)
  4. Go into gnuplot terminal by running gnuplot
  5. Run the commands to plot the dropped packets, send packets and ack packets in graph and save as image
gnuplot
plot [0:6] "sent.tahoe" with points,"dropped.tahoe", "ack.tahoe" with dots 
set terminal pngcairo
set output 'output.png'
replot
unset output
  1. For calculating avg.throughput and number of packets run
    perl ../../Utils/throughputCalculator.pl out.tr 4 0.0 4.0 1.0 example
  2. For additional details, go to the site http://www.jgyan.com/analyzer/ and upload out.nam file
