Packets, Protocols and PHP: Networking Fundamentals for Developers

Abstract

Whether you’re building APIs, deploying microservices, or just curious about what happens beneath the surface of your applications, understanding networking is essential. This talk explains the core concepts of networking – from the basics of TCP, UDP and the OSI model, to more advanced topics like routing, BGP and anycast.

You’ll gain a practical understanding of how data moves across the internet, how routing decisions are made, and why these concepts matter when building scalable, resilient applications. No prior networking experience required.
