WRED
WRED is an acronym for Weighted Random Early Detection. It is an active queue management mechanism that
provides preferential treatment of higher priority frames when traffic builds up within a queue. A frame's DP level is
used as input to WRED. A higher DP level assigned to a frame results in a higher probability that the frame is dropped
during times of congestion.
WTR
WTR is an acronym for Wait To Restore. This is the time a fail on a resource has to be 'not active' before restoration
back to this (previously failing) resource is done.
