 Explicit Congestion Notification

Explicit Congestion Notification (ECN) is a network protocol that helps manage traffic congestion in Internet Protocol (IP) networks. It is designed to provide feedback from routers to endpoints about network congestion without dropping packets, which can improve overall network performance. ### How ECN Works: 1. **ECN Marking**: - ECN enables routers to mark packets instead of discarding them when they experience congestion.
