Reproducing UPS Results for the default scenario

Instructions for reproducing UPS results on the default scenario (Internet2 1Gbps-10Gbps topology, 70% link utilization)

General:

  1. Clone the UPS repository.
  2. cd ns-allinone-2.35
  3. sudo apt-get install xorg-dev (if needed)
  4. sudo apt-get install gcc-4.4 g++-4.4 (if needed)
  5. export CC=gcc-4.4 CXX=g++-4.4
  6. ./install
  7. cd ns-2.35
  8. Open Makefile and replace "queue/sfq.o queue/fq.o queue/drr.o queue/srr.o queue/cbq.o" with "queue/sfq.o queue/fq.o queue/drr.o queue/srr.o queue/cbq.o queue/sfqcodel.o queue/random-dequeue.o queue/lifo.o queue/lstf.o queue/edge-replay.o queue/edge-tail-pkt-delay-lstf.o queue/fine-priorities.o queue/srpt.o queue/edge-fq-lstf.o"
  9. make clean; make
  10. Scripts to run various experiments can be found in ns-allinone-2.35/ns-2.35/tcl/ex/ups/scripts. All scripts should be run from this directory.
  11. Results for various experiments get stored in specific directories in ns-allinone-2.35/ns-2.35/tcl/ex/ups/

The scripts and results directories for various experiments are listed below. Specific details about result format can be found in the README files in the specific result directory. The total time taken to run each script (on a machine with 2.6GHz processor and atleast 5GB memory) has also been reported.
