Reshaping Network Traffic with eBPF and XDP - An Interactive Tutorial
Dive into an interactive tutorial exploring how to reshape network traffic using eBPF and XDP technologies. Learn about the revolutionary eBPF technology and its impact on the network stack, enabling secure code execution within the kernel for instant metrics and network security policy application. Discover how eBPF powers various open-source projects in networking, from CNIs like Cilium to monitoring tools like Pixie. Explore the eXpress Data Path (XDP) system in the Linux kernel, which offers high-performance programmable packet processing. Through hands-on exercises, create an eBPF program and utilize XDP to reshape traffic and apply routing policies that affect traffic in environments such as Kubernetes clusters. Gain a deeper understanding of the underlying technology powering popular eBPF-based open-source projects and enhance your networking expertise in this comprehensive 1-hour 13-minute workshop.
