### Patricks Code

#### Patrick Review Notes

Everything in `dev` branch.

[picoquic](https://github.com/private-octopus/picoquic) is a minimalist QUIC
implementation Patrick used to conduct his experiments with QUIC.

The wedge is the P4 Switch Patrick used for testing on hardware.
It is pre-configured to run P4 Code.

Test nodes are:

- ncs-node3-tailscale
- ncs-node4-tailscale
- ncs-node5-tailscale
- ncs-node6-tailscale
- ncs-node7-tailscale

Three folders:

- `bqm`:
  - `bqm`: Implementation of bqm along with a compilation script
  - `config`: scripts to configure bfrt - automates interactions with bfshell
  - `taildrop`: Drop bqm control packets and if queue is full (INCOMPLETE EXPLANATION)
  - `test`: Testing scripted setup of a network namespace on one host
    - `clean_env.sh`: Delete all network namespaces
    - `setup_env.sh`: Setup NS `exp_server` and `exp_client`, add interfaces/IP/ARP
      entries
    - `start_tshark_1.sh`: Runs `tshark` in the network namespace
      `exp_server` on `eno1np0`
    - `test.py`: Use scapy to send 20 UDP packets
  - `test_switch`: P4 Script and BFRT configuration for testing
  - `copy_all.sh`: Script to copy bqm and config to the Wedge
- `experiment-scripts`:
  - `experiment_set_1`: Experiment. Explanation in `README.md`
  - `experiment_set_2`: Experiment. Explanation in `README.md`
  - `experiment_set_3`: Experiment. Explanation in `README.md`
  - `experiment_set_4`: Experiment. Explanation in `README.md`
  - `experiment_set_reno1`: Experiment. Explanation in `README.md`
  - `experiment_set_reno2`: Experiment. Explanation in `README.md`
  - `experiment_set_reno3`: Experiment. Explanation in `README.md`
  - `experiment_set_reno4`: Experiment. Explanation in `README.md`
  - `results`: Results of prior experiments.
  - `cleanup_network.sh`: Delete all namespaces on each test node
  - `configure_picoquic.sh`: Compile picoquic on each test node
  - `create_folders.sh`: Create experiment folders
  - `credentials`: Git credentials
  - `diagrams.ipynb`:
  - `old.ipynb`:
  - `run_sudo.sh`: Helper script to run sudo commands via ssh
  - `set_arp_entries.sh`: Set ARP entries of test setup
  - `setup_log_locations.sh`: Copy and execute `create_folders.sh`-script on
    each test node
  - `setup_network.sh`: Setup test network. Includes:
    - Namespaces
    - Interfaces/IPs
    - Routing
    - ARP Entries (with `set_arp_entries.sh`)
  - `setup_repositories.sh`: Setup git to get picoquic on each test node
  - `sync_time.sh`: Set time on each node
  - `update_repositories.sh`: Update picoquic on each test node
- `picoquic-sync`: Local copy of the picoquic library

### RECN Code

#### 04\_-_Projekte/14-run_rpecn_tests/codes/Big_Topo

- `README.md`:
  - Explains the setup and prerequisite steps to run an experiment
  - Prerequisite Steps:
    - Setup ARP on each host
    - (When first time) Install required tools
    - Run switch program on wedge
    - Prepare Ports on wedge
    - Configure touting tables on wedge
    - Do Portshaping
    - Run experiment-script
  - Reset of setup can be done by executing `reset.sh` on each test node

## Requirements

### Notes

- Testbed setup with alveo network cards to run on host and a switch
- Pluggable network traffic generation at the experimentation stage
- Xilinx FPGA Cards will be used
- Non static testbed - Make general first especially ARP/IP/Interface and go
  from there

### Whats needed

TODO

## Plan Project

### Rough Sketch

I start by creating a rough sketch in [./sketch.md](./sketch.md).

## Implement MVP

## Refine
