TCP congestion control algorithms

TCP congestion control algorithms manage data flow over the internet to prevent network overloads. They dynamically adjust the rate at which data is sent based on current network conditions. When the network is clear, they increase the sending rate; if congestion or packet loss occurs, they reduce it to avoid causing delays or data loss. Techniques like slow start, congestion avoidance, and fast recovery help maintain efficient and reliable data transmission, ensuring that multiple users sharing the network experience smooth, fair, and stable connections.
