Enhanced Quality of Service (QOS)
Most networks are comprised of various types of real-time and non real-time services. With its
four prioritized output queues, the EEI can insure that higher priority traffic like voice and
network controls are not backed up behind low priority traffic such as bulk transfers and games.
In addition, EEI provides the operator with more control over how the QOS determination is
made and how the queues are processed. And in all cases, the QOS determinations and queuing
is performed at line speed.
Figure F-7 illustrates the prioritized queues and the traffic normally associated with those queues.
