Explicit Congestion Notification

Explicit Congestion Notification (ECN) is a network feature that helps manage data traffic efficiently. When network devices experience congestion, instead of dropping data packets, they mark these packets to signal congestion to both sender and receiver. This allows the sender to slow down data transmission proactively, reducing delays and preventing packet loss. ECN improves overall network performance by responding to congestion dynamically, facilitating smoother data flow without the need for retransmissions or connection drops, ultimately leading to a more reliable and efficient internet experience.
