Networks in C++ - What's Actually Changing?

Explore the evolving landscape of network programming in C++ through this comprehensive conference talk from CppCon 2025. Discover how network engineering is advancing beyond traditional abstractions, examining new protocols like QUIC that are being universally deployed and multiple attempts to define network interfaces beyond the historical POSIX API. Learn about the intersection of networking and C++ development, including new paradigms for signaling between applications and networks, performance considerations, and developments in asynchronous models for network interfacing. Understand why modern application requirements for performance and responsiveness demand practically usable asynchronous approaches, and gain insights into how network interfaces and operational modes are evolving beyond their traditionally assumed fixed nature. Benefit from the expertise of Ignas Bagdonas, a Principal Architect with Equinix who brings over two decades of network engineering experience covering operations, deployment, design, architecture, development, and standardization aspects across multiple large service provider and enterprise networks worldwide.
