TSNavig8 - Demo: Interactive Off-the-Shelf In-Car TSN Testbed

The described software is presented in the paper "Demo: Interactive Off-the-Shelf In-Car TSN Testbed", accepted for publication in the IEEE Vehicular Networking Conference (VNC 2024).

Abstract

TSNavig8 represents an interactive and affordable Time-Sensitive Networking (TSN) testbed built using off-the-shelf hardware. It provides a user-friendly interface for configuring an in-car TSN testbed and experiencing real-time interactions, such as assessing the impact of background noise traffic on automotive LiDAR sensor data, with support for configuring the IEEE 802.1Qbv standard.

Installation

Clone the repository

git clone ['link to git repository']

Install Dependencies npm install

Project setup

1. Run the Python server

cd backend
mkdir logs

Architecture

Project structure

• backend folder

  This folder contains the following Python files:

  • server.py - Python server that listens on UDP port 6699 where MSOP packets are sent from the LiDAR. This UDP listener processes the payload of the datagrams and converts the polar coordinates (angle and distance) to Cartesian coordinates. Once completed, the messages containing the ⟨x, y, z, distance⟩ are sent to the web client application. The distance measured in centimeters is used to compute the color of each point.

  • throughput_server.py - Python server responsible for computing the real-time bandwidth utilization every second and sending this data to the web client application.

  • config_server.py - Python server used to perform hardware configuration over the Secure Shell (SSH) protocol based on input parameters provided by the user.

• backend/tas_configs/bridge20 folder

  • This folder contains examples of Time-Aware Shaper configuration files for RELY-TSN-Bridge v20.1.11.

• backend/tas_configs/bridge22 folder

  • This folder contains examples of Time-Aware Shaper configuration files for RELY-TSN-Bridge v22.3.0.

• src/components folder This folder contins the following components:

  • PlotBandwidthComponent.vue - uses Chart.js to plot the bandwidth utilization measured in Mbit/s.

  • PlotLidarComponent.vue - uses Three.js library to render cloud points, allowing the user to visualize scanned data from the LiDAR sensor.

  • NoiseComponent.vue - enables the user to configure the size of the ethernet frame , Priority Code Point (PCP) and bandwidth usage in percentage units of the traffic sent by the RELY-TRAF-GEN v20.1.0.

  • TasComponent.vue - enables the user to configure the Time-Aware Shaper TAS configuration by specifying the number of slots,their duration, and which priority queues are enabled. Example of TAS configuration files are presented in backend/tas_configs/ folder.

  • FooterComponent.vue - this component represents the footer section of the application.

  • HeaderComponent.vue - this component represents the header section of the application.

  • MainComponent.vue - this component represents the main content area of the application.
