Linux Interface Latency Testing

This is a general reference for introducing artificial network latency on Linux when testing how a protocol behaves as latency increases.

The standard tool is tc with the netem qdisc.

Overview

• Egress delay on an interface is straightforward with tc netem.
• Ingress delay is usually handled by redirecting ingress traffic to an ifb device and applying netem there.

How to Access a USB Device from WSL2

If you use Windows Subsystem for Linux 2 (WSL2), you've probably noticed that USB devices do not automatically appear inside your Linux environment. That's by design: WSL2 runs in a lightweight VM, so direct hardware access works differently than it does on a native Linux machine.

The supported way to pass a USB device from Windows into WSL2 is with usbipd-win, a Windows tool that exposes USB devices to WSL over USB/IP.

This guide walks through the setup and shows how to attach, verify, and detach a USB device from WSL2.
