Building an eBPF/XDP NAT-Based (Weighted) Round Robin Load Balancer from Scratch

by Teodor Janez Podobnik

In this lab, you’ll build a NAT-based eBPF/XDP load balancer from scratch and implement both round-robin and weighted round-robin backend selection. Along the way, you’ll learn how to manage state in eBPF maps and distribute traffic across backends based on simple and capacity-aware scheduling strategies.

Building an eBPF/XDP NAT-Based (Weighted) Least Connection Load Balancer from Scratch

by Teodor Janez Podobnik

In this lab, you will extend the eBPF/XDP-based NAT load balancer implementation with the least-connections to a weighted least-connections algorithm that accounts for backend capacity.
