Distributed Computing System for Autonomous Driving System

I designed a distributed computing system to distribute the load of the autonomous driving system and increase stability. Considering cost optimization and equipment supply, I used multiple network switches with appropriate performance instead of using a single high-performance network switch. To ensure stability, I isolated the network according to the type of sensor instead of stacking network switches, and the computing units are connected to multiple networks using two or more NICs. I used network interface bonding if necessary to meet performance requirements. For installation convenience, I used Ansible, and to reduce internet access costs during installation, I used a single computer as a proxy to cache the necessary data. I also set up a network file system accessible from all computing units for debugging and building on-site. I synchronized the time of all network devices, including sensors, using PTP.
