How Linux XDP Transforms High-Speed Packet Processing

Episode 130 of The Linux Podcast dives into the eXpress Data Path (XDP), a technology that accelerates network packet processing by attaching eBPF programs directly to network drivers. Lucas explains how XDP bypasses the kernel's networking stack to achieve millions of packets per second with minimal latency, making it essential for DDoS mitigation, edge computing, and high-frequency trading. Luna asks about real-world use cases and the challenges of writing safe, efficient XDP programs. The episode also touches on why container orchestrators and cloud providers are adopting XDP for load balancing and security filtering. A must-listen for any Linux professional working with high-throughput networking or performance tuning.
