As part of this thought exercise, I’ve been thinking about simplifying and optimizing process of sharing state between many nodes in a network which has led me to playing around with the UDP protocol. This post explores a na├»ve peer discovery implementation using UDP multicast. With all the modern languages and tools we use, it’s easy to forget how simple yet powerful some low-level protocols are.
