Easy to configure.
Bandwidth guarantee for
packets from cooperative
(interactive) sources
(such as TCP packets).
Reduces jitter.
Reduces the delay for
interactive applications
with a small amount of
data.
Bandwidth assignment
based on traffic priority.
Automatic bandwidth
reassignment to increase
bandwidth for each class
when the number of traffic
classes decreases.
Flexible traffic
classification based on
rules and differentiated
queue scheduling
mechanisms for EF, AF
and BE services.
Highly precise bandwidth
guarantee and queue
scheduling on the basis of
AF service weights for
various AF services.
Absolute preferential
queue scheduling for the
EF service to meet the
delay requirement
real-time data.
Overcomes the PQ
disadvantage where some
low-priority queues are
not serviced by restricting
the high-priority traffic.
WFQ scheduling for
best-effort traffic (the
default class).
Provides preferential
treatment for real-time
applications.
Performs traffic policing
before enqueuing packets
to prevent other queues
from being starved.
64
Disadvantages
The processing speed is slower than
FIFO.
The system overheads are large.

Applicable only to delay-sensitive
applications, such as voice and
video.
