Using eXpress Data Path (XDP) maps in RHEL 8: Part 2

This article, the second is a series about eXpress Data Path (XDP), explores maps--a more-advanced eBPF feature--and some common pitfalls and basic debugging techniques.

Achieving high-performance, low-latency networking with XDP: Part I

This article guides you through your first XDP program, building a working example from zero and allowing you to build a light-speed network application from there. With an XDP program, you can achieve unprecedented speed in packet filtering, because a modern driver with XDP support can easily handle more than 14 Mpps.
