Network congestion control

Network congestion control is a set of techniques used to manage data flow on the internet, ensuring that no single network path becomes overwhelmed with too much information at once. When many devices send data simultaneously, it can cause delays or data loss. Congestion control algorithms detect these issues and adjust the rate of data transmission—slowing down when the network is busy and speeding up when it's clear. This helps maintain smooth, efficient data transfer, prevents network collapse, and ensures all users experience reliable connectivity.
