Facebook releases Augmented Traffic Control, an open source tool for simulating network conditions

Augmented Traffic Control (ATC) is a tool to simulate network conditions. It allows controlling the connection that a device has to the internet. Aspects of the connection that can be controlled include:

bandwidth, latency, packet loss, corrupted packets, packets ordering

In order to be able to shape the network traffic, ATC must be running on a device that routes the traffic and sees the real IP address of the device, like your network gateway for instance.

This tool should be useful to anyone building an app on the network. CALI could use this to test behavior of Lessons on a bad connection, something we’ve been thinking about recently.
