Network Traffic Rate Limiting with eBPF/XDP Coding Lab Now Available

Last week, I released the first eBPF tutorial about XDP, focusing on fundamentals like the attachment point, capturing packets, and parsing them.

That was a good starting point, but building useful programs also requires other eBPF features such as maps and helper functions.

The complexity of real applications naturally depends on the problem, but one of the simplest—and also one of the first—examples I built early on was packet rate limiting.

So here comes the new coding lab: https://labs.iximiuz.com/tutorials/ebpf-ratelimiting-dbc12915

I’ve received countless nice messages from people following the labs, and I’m really happy about the positive impact they’re having on the eBPF community.

Still, I’m curious what you think about this:
