Implementation Details (details)

Implementation of FQ-PIE was done in NS3

Files

• fq-pie-queue-disc.h (Click here)
  This file contains the basic definition of the the FqPieFlow class and FqPieQueueDisc class.

• fq-pie-queue-disc.cc (Click here)
  This file contains all the declarations of the functions in fq-pie-queue-disc.h

Steps to reproduce the results :

• For validation of fq-pie, it is compared to pie :
  • fq-pie-validation and pie-validation are compared
• For evaluation of fq-pie, it is compared with fq-codel :
  • fq-pie-light-tcp and fq-codel-light-tcp
  • fq-pie-mix-traffic and fq-codel-mix-traffic
  • fq-pie-heavy-tcp and fq-codel-heavy-tcp
• List of example-files :
  • fq-pie-light-tcp
  • fq-codel-light-tcp
  • fq-pie-mix-traffic
  • fq-codel-mix-traffic
  • fq-pie-heavy-tcp
  • fq-codel-heavy-tcp
  • fq-pie-validation
  • pie-validation

Steps to run :

• Clone the repository

• Run the following initialising code :

    cd ns3/
    ./waf configure --enable-examples
    ./waf build
  

• To run an simulation for example-file (Check the list of example files above) :
  

  ./waf –run example-file

• If a validation script is run you have a Validation folder in your ns3 which has your example-file’s sub folder containing simulation documents (cwnd traces, pcap files and queue traces) which can be analysed

• If a evaluation script is run you have a Evaluation folder in your ns3 which has your example-file’s sub folder containing simulation documents (cwnd traces, pcap files and queue traces) which can be analysed

(PS: For getting results in FQPIE, one must change the directory to desired examples directory in fq-pie-queuedisc.cc )
