7.13.12 Weighted Random Early Detection Configuration
Weighted random early detection (WRED) is a queueing discipline for a network
scheduler suited for congestion avoidance. 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 traffic class.
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 quality of
service prioritization is made possible for important packets from a pool of
packets using the same buffer.
It is more likely that standard traffic will be dropped instead of higher prioritized
traffic.
