AVB/TSN Integration and Validation for Real-Time Camera Networks

Verified AVB/TSN (IEEE 1722 / 802.1AS) compliance and deterministic data flow for real-time in-vehicle camera systems, ensuring reliable synchronization and bandwidth management across the network.

Project Overview

This project focused on validating and integrating Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) protocols for Magna’s distributed camera architecture.
The goal was to guarantee synchronized, low-latency video and control traffic across multi-node Ethernet networks, supporting real-time perception and surround-view applications.

I implemented and verified TSN features such as time synchronization (IEEE 802.1AS), traffic shaping, and stream reservation (IEEE 802.1Qat), ensuring deterministic delivery even under heavy bus load.
As part of the effort, I updated register configurations for the Marvell Ethernet switch and integrated custom switch bring-up scripts into the embedded Linux system.

This work provided the foundational network timing and reliability required for distributed camera pipelines and sensor fusion frameworks across future zonal vehicle architectures.

Key Details / Outcomes

Protocol Compliance: Validated end-to-end AVB/TSN stack for IEEE 1722 (streaming) and 802.1AS (timing).

Integrated Switch Configuration: Automated register setup and switch initialization through custom Linux scripts.

Stream Reservation: Implemented SRP-based bandwidth allocation ensuring deterministic throughput for surround-view video streams.

Improved Reliability: Reduced frame jitter and stream interruptions under concurrent camera loads.

Challenges & Learnings

Understanding and debugging precise timing interactions between PTP synchronization and TSN traffic classes.
Verifying deterministic latency behavior across heterogeneous endpoints.
Integrating switch-level QoS, VLAN, and SRP configurations with Linux network stack scripting.
Establishing automated validation scripts to continuously monitor stream reservation and timestamp drift.
