## README

# HPCC simulation
[Project page of HPCC](https://hpcc-group.github.io/) includes latest news of HPCC and extensive evaluation results using this simulator.

This is the simulator for [HPCC: High Precision Congestion Control (SIGCOMM' 2019)](https://rmiao.github.io/publications/hpcc-li.pdf). 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)](https://liyuliang001.github.io/publications/pint.pdf).

## 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 [HPCC](https://liyuliang001.github.io/publications/hpcc.pdf) Figure 11.
Refer to the README.md under it for more details.

## Extended
1. 这个simulator在HPCC的基础上实现了IRN transport logic以及我们的custom routing。
2. [k-shortest-path](simulation/ksp)算法。
## 运行
1. 建立相应的文件夹（配置文件存放、输出文件存放等等），命令如下：
`./gen_dir.sh`
2. 生成所需要的运行文件（流文件、拓扑文件、配置文件），命令如下：
`./gen-conf-files.sh`
3. 等待所有文件生成之后（就可以运行），命令如下：
`./waf --run "scratch/fat-tree mix/experiment/config/fat-tree/dcqcn/16pod/non-uniform/pfc/1G/70/config.txt"`
