Weighted Random Early Detection (WRED) is a congestion management technique used in networking, particularly within routers and switches, to manage queue lengths and prevent congestion before it occurs. It builds upon the principles of Random Early Detection (RED), which is a method of packet dropping designed to minimize queuing delays and reduce the chances of congestion.
