The blog discusses the engineering intricacies of building a low-latency peer discovery system for autonomous vehicles.The architecture is designed with three core layers and carefully chosen tools, protocols, and techniques for resilience, scalability, and efficiency.The system separates on-car components for real-time tasks from server-side components for centralized control functions.Key components include mDNS/DNS-SD for local discovery, Kademlia DHT for peer discovery, and Delta Compression for bandwidth efficiency.
