Handling of Traffic Classes

For the handling of traffic classes, the device provides:
Strict Priority
Description of Strict Priority
With the Strict Priority setting, the device first transmits all data packets
that have a higher traffic class before transmitting a data packet with the
next highest traffic class. The device transmits a data packet with the
lowest traffic class only when there are no other data packets remaining
in the queue. In some cases, a high level of data traffic can prevent
packets with lower traffic classes from being sent.
In applications that are time- or latency-critical, such as VoIP or video, this
method ensures that high-priority data is sent immediately..
