Project page of HPCC includes latest news of HPCC and extensive evaluation results using this simulator.

This is the simulator for HPCC: High Precision Congestion Control (SIGCOMM' 2019). It also includes the implementation of DCQCN, TIMELY, DCTCP, PFC, ECN and Broadcom shared buffer switch.

We have update this simulator to support HPCC-PINT, which reduces the INT header overhead to 1 to 2 byte. This improves the long flow completion time. See PINT: Probabilistic In-band Network Telemetry (SIGCOMM' 2020).

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

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

We provide a few analysis scripts under analysis/ to view the packet-level events, and analyzing the fct in the same way as HPCC Figure 11. Refer to the README.md under it for more details.
