The Random Early Detection (RED) algorithm works by proactively dropping more and more input packets as the queue occupancy builds up. When the queue is full or almost full, RED effectively works as Tail Drop. The Weighted RED (WRED) -algorithm uses a separate set of RED thresholds for each packet color and uses -separate set of RED thresholds for each packet color. +algorithm uses a separate set of RED thresholds for each packet color. Each hierarchy leaf node with WRED enabled as its congestion management mode has zero or one private WRED context (only one leaf node using it) and/or zero, -- 2.51.0
