## Accelerate Istio-CNI with ebpf Xu Yizhou & Guo Ruijing ## Agenda • Istio-CNI • tcp/ip stack overhead between sidecar and service • Background knowledge of ebpf • Acceleration for Inbound/Outbound/Envoy Inbound/Outbound/Envoy to Envoy ## I stio-CNI - The Istio CNI plugin performs the Istio mesh pod traffic redirection in the Kubernetes pod life-cycle’s network setup phase. - Removing the requirement for the the NET_ADMIN and NET_RAW capabilities for users deploying pods into the Istio mesh. The Istio CNI plugin replaces the functionality provided by the istio-init container. ![Image](/uploads/documents/5/
