Kubernetes networking has come a long way since the early days of kube-proxy and iptables. But as workloads become more latency-sensitive and network-intensive - particularly in edge, Telco, and private cloud environments - it's clear that traditional solutions like MetalLB or kube-proxy are hitting their limits.

In this talk, we'll dive into LoxiLB, a high-performance, cloud-native L4 load balancer built with eBPF. We'll show how it can replace or complement kube-proxy and MetalLB, especially in scenarios where:

- Load balancing needs to scale across thousands of Services
- Network throughput and latency become critical
- Multi-path routing, BGP, ECMP

Through a series of real-world benchmarks, we'll compare:

- MetalLB vs LoxiLB throughput under high connection load
- Latency distribution
- Scalability across nodes using ECMP

With LoxiLB and eBPF, we’re entering a new phase of Kubernetes networking: one where load balancing is programmable, observable, and built for scale.
