This is an NS-3 simulator for HPCC: High Precision Congestion Control (SIGCOMM'19). It also includes the implementation of DCQCN, TIMELY, DCTCP, PFC, ECN and Broadcom shared buffer switch. The full paper can be found at: https://rmiao.github.io/publications/hpcc-li.pdf

It is based on NS-3 version 3.17.

If you have any questions, please contact Rui Miao ([email protected]).

./waf configure

Please note if gcc version > 5, compilation will fail due to some ns3 code style. If this what you encounter, please use:

CC='gcc-5' CXX='g++-5' ./waf configure

Please see mix/config.txt for example.

mix/config_doc.txt is a explanation of the example (texts in {..} are explanations).

The direct command to run is: ./waf --run 'scratch/third mix/config.txt'

We provide a run.py for automatically generating config and running experiment. Please python run.py -h for usage. Example usage: python run.py --cc hp --trace flow --bw 100 --topo topology --hpai 50
