HPCC simulation

This is the simulator for HPCC, HPCC-PINT, HPCC-LINT, and HPCC-DINT, which are other versions of HPCC implementing PINT, LINT, and DINT protocols This simulator is modified from the HPCC-PINT repository, which is introduced in PINT: Probabilistic In-band Network Telemetry (ACM SIGCOMM 2020) and implements LINT and DINT based on the original DINT repository.

NS-3 simulation

The ns-3 simulation is under simulation/. Refer to the README.md under it for more details.

Traffic generator

The traffic generator is under traffic_gen/. Refer to the README.md under it for more details.

Analysis

We provide a few analysis scripts under analysis/ to view the packet-level events, and analyzing the fct in the same way as PINT Figure 7 and 8. Refer to the README.md under it for more details.

Generating the figures in the paper

1. Generate traffic workload at 50% load: bash gen_traffic_files.sh

2. Set error rate: python set_error_rate.py <new error rate>

• By default the error rate is set to 0

3. Run simulations:

• First enter the folder and configure: bash build.sh

• HPCC-PINT under web search: bash run_hpcc_pint1_wb.sh

• HPCC-PINT under Hadoop: bash run_hpcc_pint1_fb.sh

• HPCC-PINT with p=1/16 of packets carrying feedback under web search: bash run_hpcc_pint16_wb.sh

• HPCC-PINT with p=1/16 of packets carrying feedback under Hadoop: bash run_hpcc_pint16_fb.sh

• HPCC-PINT with p=1/256 of packets carrying feedback under web search: bash run_hpcc_pint256_wb.sh

• HPCC-PINT with p=1/256 of packets carrying feedback under Hadoop: bash run_hpcc_pint256_fb.sh

• HPCC under web search: bash run_hpcc_wb.sh

• HPCC under Hadoop: bash run_hpcc_fb.sh

• Each simulation will run for about 1 day.

4. Get the fct analysis result

• First enter the folder cd analysis

• Our plot script requires python-tk. So if you don't have it, please install it (e.g., sudo apt install python-tk).

• Fig 7: bash plotVsHPCC.sh. Figures are called web_search_95p.pdf and facebook_95p.pdf.

• Fig 8: bash plotProbHPCC.sh. Figures are called ProbHPCC_PINT_wb.pdf and ProbHPCC_PINT_fb.pdf.
