Augmented Traffic Control: A tool to simulate network conditions

What this post added

Introduced Augmented Traffic Control (ATC), a tool developed to simulate diverse network conditions (initially attempted with 2G, then pivoted to Wi-Fi based simulations) to allow engineers to test applications under realistic, often suboptimal, network environments. ATC enables simulation of 2G, Edge, 3G, and LTE networks, specifically targeting common connectivities in countries like Brazil, India, Indonesia, Kenya, Nigeria, and the Philippines. The tool was integrated into the campus Wi-Fi network and made available via APIs for automated testing, reducing the need for extensive A/B testing and improving development efficiency for features like Messenger and download functionality. ATC was open-sourced on GitHub.
