Bypassing Conntrack - Optimizing K8s Service by Enhancing IPVS with EBPF

Explore a conference talk that delves into optimizing Kubernetes Service performance through an innovative approach to load balancing. Learn about IPVS-eBPF, a novel load balancer developed by Tencent that enhances IPVS by bypassing Netfilter and utilizing eBPF for SNAT operations. Discover how this solution achieves significant throughput gains compared to traditional IPVS, with a 22% improvement for TCP persistent connections and a 64% boost for TCP short connections. Gain insights into the technical challenges faced during development, eBPF programming experiences, and a comparison with existing Kubernetes load balancers. This 26-minute presentation from CNCF's KubeCon + CloudNativeCon North America 2020 Virtual offers valuable knowledge for developers and end-users working with Kubernetes and related cloud-native technologies.
