Explicit Congestion Notification (ECN)

Explicit Congestion Notification (ECN) is a network feature that helps reduce internet traffic congestion. When a network path is getting crowded, ECN signals to the sender and receiver that there's potential congestion, allowing them to slow down data transmission before packets are dropped. This proactive communication helps manage traffic smoothly, preventing delays and packet loss. ECN works by marking packets rather than discarding them, making the network more efficient and ensuring quicker, more reliable data delivery without noticeable interruptions.
