Accelerating Transparent Ingress Proxy with eBPF and Envoy
This lab teaches you how to use eBPF socket acceleration to speed up communication between processes on localhost and optimize a transparent Envoy proxy setup. You will implement techniques that bypass parts of the kernel networking stack, allowing data to be transferred more directly between sockets to improve throughput and reduce latency.

Transparent Ingress Proxy with eBPF and Envoy
This lab shows how to use eBPF to transparently redirect inbound traffic through an Envoy proxy on the server side, without modifying the application or client. You’ll learn how eBPF can intercept and restore connections so the service remains unaware of the proxy in the network path.

Transparent Egress Proxy with eBPF and Envoy
This lab teaches you how to use eBPF to transparently intercept and redirect a client's outgoing traffic to an Envoy proxy without requiring any changes to the application code. You will build a system that recovers original connection metadata via socket-level hooks and uses SO_MARK to prevent infinite routing loops, replacing traditional, complex iptables rules with a high-performance eBPF alternative.
