High Quality Content by WIKIPEDIA articles! Weighted random early detection (WRED) is a queue management algorithm with congestion avoidance capabilities. It is an extension to Random early detection (RED) where a single queue may have several different queue thresholds. Each queue threshold is associated to a particular IP precedence or DSCP (for DiffServ), etc.. For example: A queue may have lower thresholds for lower priority packet. A queue buildup will cause the lower priority packets to be dropped, hence protecting the higher priority packets in the same queue. In this way QoS prioritization is made possible for important packets from a pool of packets using the same buffer.
