Patricks Code

Patrick Review Notes

Everything in dev branch.

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
