Figure 11 - Buffer Partition Scheme Used to Implement MVTX2604 AG Buffer Management
7.9.1 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.
