Additive Increase/Multiplicative Decrease (AIMD)

Additive Increase/Multiplicative Decrease (AIMD) is a control method used in network communication to manage data flow. When a connection is active, the system gradually increases the data transmission rate in small, fixed steps (additive increase) to find the maximum efficient speed. If congestion or packet loss occurs, it sharply reduces the rate by multiplying it by a smaller factor (multiplicative decrease) to prevent overloading the network. This balance helps optimize data transfer, preventing congestion while maintaining high throughput efficiently.
