Congestion Control

Congestion control is a fundamental mechanism in TCP that prevents excessive data transmission from overwhelming the network, ensuring stable and efficient communication. In server-side game development, congestion control helps maintain smooth gameplay by dynamically adjusting the data flow based on network conditions. TCP employs various congestion control algorithms, such as Reno, CUBIC, and BBR, to detect congestion and reduce packet loss. These algorithms regulate the senders transmission rate using strategies like slow start, congestion avoidance, and fast recovery. Proper tuning of congestion control mechanisms is critical for minimizing lag, preventing packet drops, and optimizing multiplayer game performance, especially in high-traffic scenarios.
