Westwood congestion control algorithm

Westwood congestion control is a method used to manage how data is sent over a network, especially in high-speed connections. It adjusts the sending rate based on feedback from the network, specifically by estimating the current network capacity through acknowledgments received from the receiver. If the network is congested, it reduces the data rate; if it's clear, it increases. Unlike simpler methods, Westwood uses real-time measurements to better match the sending pace with available bandwidth, leading to improved performance, fewer delays, and more efficient data transfer.
