Envoy Mesh Acceleration: From Iptables to Fully BPF

Explore Envoy mesh acceleration techniques in this conference talk that transitions from iptables to fully BPF-based solutions. Delve into the challenges of transparent traffic hijacking and its impact on system performance. Examine current solutions, including Cilium and lightweight approaches, and understand how iptables redirections affect sockmap match results for inbound and outbound traffic. Discover a novel iptables-free solution that utilizes eBPF for traffic direction, provides transparent outbound traffic redirection, and offers an integrated control plane for Daemonset deployment. Learn about eBPF architecture, sockmap implementation, and performance improvements in this comprehensive exploration of service mesh acceleration techniques.
