Explore low-latency, deterministic networking using XDP sockets in standard Linux through this 28-minute conference talk by Magnus Karlsson and Björn Töpel from Intel Corporation. Delve into the challenges of high-throughput, low-latency packet processing in time-sensitive networking applications and discover how XDP sockets, introduced in Linux 4.18, offer a solution that maintains Linux security properties while delivering sub-microsecond packet latencies. Learn about the user space implementation, kernel and driver architecture, and performance evaluation of XDP sockets. Gain insights into topics such as network interface cards, UDP sockets, XP descriptors, system calls, drivers, and benchmarking techniques for optimizing network performance.
