7.8.1 Dropping When Buffers Are Scarce
Summarizing the two examples of local dropping discussed earlier in this chapter:
If a queue is a delay-bounded queue, we have a multi-level WRED drop scheme, designed to control delay
and partition bandwidth in case of congestion.
If a queue is a WFQ-scheduled queue, we have a multi-level WRED drop scheme, designed to prevent
congestion.
In addition to these reasons for dropping, we also drop frames when global buffer space becomes scarce. The
function of buffer management is to make sure that such dropping causes as little blocking as possible.
