TCP congestion control

TCP congestion control is a technique used in computer networks to manage data traffic flow and prevent network overload. When a device sends data over the internet, it gauges the available bandwidth by monitoring packet loss and delays. If the network becomes congested, TCP reduces the data transmission rate, like easing off the gas in a traffic jam. As conditions improve, it gradually increases the rate again. This dynamic adjustment helps ensure stable and efficient data transfer, avoiding disruptions, and maintaining reliable communication between devices.
